Difference Between Twisted Pair Cable and Coaxial Cable

by Fiber-MART.COM

A wire or cable is an indispensable element in communication system for connecting optical devices like optical transceivers, router and switch. Recently the most common cable types deployed in communication system are fiber optic cable, twisted pair cable and coaxial cable. Both twisted pair cable and coaxial cable are copper cables, so what’s the difference between them? This article may help you sort it out.

 

Twisted Pair

 

Twisted pair cables as the names implies, consists of a pair of cables twisted together, which has been utilized in telecommunication field for a long time. The twisting can avoid noise from outside sources and crosstalk on multi-pair cables, so this cable is best suited for carrying signals. Basically, twisted pair cable can be divided into two types: unshielded twisted-pair (UTP) and shielded twisted-pair (STP).

 

twisted-pair

 

UTP is for UNshielded, twisted pair, while STP is for shielded, twisted pair. UTP is what's typically installed by phone companies and data communication (though this is often not of high enough quality for high-speed network use) and is what 10BaseT Ethernet runs over. However, STP distinguishes itself from UTP in that it consists of a foil jacket which helps to prevent crosstalk and noise from outside source. It is typically used to eliminate inductive and capacitive coupling, so it can be applied between equipment, racks and buildings.

 

Coaxial Cables

 

Coaxial cable is composed of an inner solid conductor surrounded by a paralleled outer foil conductor that is protected by an insulating layer. A coaxial cable has over 80 times the transmission capability of the twisted-pair. Coaxial cable has also been the mainstay of high speed communication and has also been applied to network with 10 Gigabit links data centers, because it is proved to be cost efficient for short links within 10 m and for residential network.

Comparison Between Twisted Cable and Coaxial Cable

 

Most people now are quite familiar with what coaxial cables are, as they are used in almost every home for cable television connections. These data cables are also popular in local area networks (LAN) because they are highly resistant to signal interference, which also gives coax cables the ability to support longer cable lengths between two devices.

 

The biggest advantage of twisted cables is in installation, as it is often thinner than coaxial cables and two conductors are twisted together. However, because they are thinner, they can not support very long runs. These tightly twisted designs cost less than coaxial cables and provide high data transmission rates. They connect with the RJ45 connector, which looks similar to a telephone jack but is designed for twisted pair pins.

 

In the end, twisted pair cabling is better suited when cost and installation are an issue and if EMI and crosstalk are not too much of a problem. But for coaxial cable, it supports greater cable lengths, and can be shielded in a variety of ways—with a foil shield on each conductor, a foil or braid inside the jacket or a combination of individual conductor and jacket shielding.

 

Additional Information About Fiber Optic Cables

 

Besides Twisted and coaxial cables, here comes a new generation of transmission media—fiber jumper. Fiber optic cables have a much greater bandwidth than metal cables, which means they can carry more data. They are also less susceptible to interference. For these two reasons, fiber optic cables are increasingly being used instead of traditional copper cables despite that they are expensive. Nowadays, two types of fiber optic cables are widely adopted in the field of data transfer—single mode fiber optic cables and multimode fiber optic cables.

 

LC-SC fiber patch cable

 

Single mode optical fiber is generally adapted to high speed, long-distance applications. While a multimode optical fiber is designed to carry multiple light rays, or modes at the same time, which is mostly used for communication over short distances. Optical fiber cables are also available in various optical connectors, such as LC to SC patch cord, LC to ST fiber cable, SC FC patch cord, etc. The picture above shows a LC to SC patch cord.

 

Conclusion

 

Some engineers confirm that fiber optic cables is sure to be the dominant transmission media in telecommunication field, while others hold that copper cables will not be out of the stage. Thus, whether to choose fiber optic cables, twisted cables or coaxial cables, it is advisable for you to have a full understanding of your application before selecting these data cables.

Benefits of Fiber Optic and Passive Optical LAN Test

by Fiber-MART.COM

In recent years, passive optical LANs have gained significant popularity as an alternative to horizontal copper structured cabling in a variety of enterprise spaces.

 

The technology brings fiber out of the riser backbone and data center, and with that comes the need for fiber technicians to test these systems out in the horizontal space.

 

Let’s take a closer look at these passive optical deployments.

 

 

Passive optical LANs are a point-to-multipoint fiber architecture that use passive optical splitters to divide the signal from one singlemode fiber into multiple fiber signals.The signals are transmitted simultaneously in both directions over separate wavelengths using wavelength division multiplexing (WDM) technology—1310nm for upstream data and 1490nm for downstream data.

 

Available in a variety of split ratios such as 1:8, 1:16, and 1:32, optical splitters basically serve the same purpose as a network switch, but they are not electrically powered—that’s why the technology is referred to as “passive.”

 

The singlemode fiber that arrives at the splitter originates at an optical line terminal (OLT) typically located in a data center or main equipment room.

 

From the splitter, multiple fibers connect to optical network terminals (ONTs) that convert the optical signal into multiple balanced signals for transmission over twisted-pair copper cabling to end devices.

 

What are the Benefits?

 

Because passive optical LANs use singlemode fiber, they are not limited by the 100-meter channel distance of copper but instead can reach distances of 20 kilometers.This is ideal for large facilities, or really any facility where 100 meters is not feasible.

 

In addition to eliminating the distance limitation, the primary cost-saving benefits of passive optical LANs include the ability to eliminate telecommunications rooms and the associated power and cooling infrastructure.The smaller, lighter singlemode fiber cables used in these systems also reduces pathway and space requirements.

 

Other benefits touted by proponents of passive optical LANs, and of fiber systems in general, include improved security and eliminating the crosstalk and EMI/RFI concerns associated with copper cabling.

 

 

How are they Tested?

 

Just like any fiber optic system, a passive optical LAN requires insertion loss testing.And just like any fiber system, the overall channel loss is based on the end-to-end path between application specific equipment—the OLT and ONT in the case of the passive optical LAN.That means that everything in between—cable, connectors, splitters, and splices—attributes to loss.And just like any fiber optic system, connector cleanliness remains vital.That means the connectors should be inspected for contamination.

 

For passive optical LANs, the acceptable insertion loss is a minimum of 13dB and a maximum of 28dB at a 20km distance.The singlemode fiber used in a passive optical LAN should also be tested at both the 1310nm and 1490nm wavelengths.And test reference cords must include the angled polish contact (APC) style connector to match those used in passive optical LANs.

 

Best practices for passive optical LAN testing will be included in the upcoming international standard IEC 61280-4-3, which in keeping with existing TIA and ISO/IEC standards, specifies a light source/power meter for Tier 1 testing and an OTDR for Tier 2 testing in the upstream direction.

How to Clean the Dirt and Dust In Data Center

by Fiber-MART.COM

Wipe your finger on a distribution cabinet or a patch panel in a data center. Then watch your finger, can you see the scene shown in the picture on the right side? Your finger is attached with dust or dirt. This situation is so familiar to most telecom engineers working in data centers. However, how many people really care about it? You might recognize that the data center needs cleaning, but you might just think about it. This is the contaminant that can be seen and checked directly by eyes or touching. How about those dust or dirt inside the equipment? Over time, without timely cleaning, the accumulation of dirt and dust will lead to problems like overheating and various network failures. This is just the start of troubles, more are there to be deal with, if no proper action was taken.

 

Why Clean the Data Center?

What would happen, if there is no regular cleaning in data center? As mentioned, the most direct result of contaminant is overheating. Why? Dust and pollutants in the data center are usually light-weight. If there is air flow, dust or dirt will move with it. The cooling system of the data center is largely depending on server fan which can bring the dust and dirt into the cooling system. The accumulation of these contaminant can cause fan failure or static discharge inside equipment. The heat dissipation will need more time and heat emission efficiency is limited. The following picture which shows the contaminant at a server fan air intake, answers this question intuitively.

 

With the cooling system being affected by the dust and dirt, the risk of the data center will be increased largely. Contaminants won’t stop at cooling system, they will capture every possible place where they can get to. In addition, today’s data center is largely depend on electronic equipment and fiber optic components like fiber optic connectors, which are very sensitive to contaminants. Problems like power failures, loss of data and short circuit might be happened if the contaminants were not cleaned. What’s worse, short circuit might cause fire in data center, which could lead to irreparable damage.

 

Dust and dirt can also largely affect the life span of data center equipment as well as their operation. Cleaning and uptime usually run hand-in-hand. The uptime of a data center will be reduced if there are too many contaminants. Cleaning the data center regularly would be a good deal to reduce data center downtime and extend the life span of data center infrastructure equipment, comparing the cost of restarting the data center and repairing or replacement of the equipment.

 

Last but not least, Data center cleaning can offer an aesthetic appeal of a clean and dust-free environment. Although it is not the main purpose, but a clean data center can present a more desirable working environment for telecom engineers, especially for those who need to install cable under a raised floor or working overhead racks and cabinet. No one would reject the cleaning data center.

 

Contaminants Sources of Data Center

It is clear that data center cleaning is necessary. But how to keep the data center clean? Before take action, source of contaminants of data center should be considered. Generally, there are two main sources, one is inside the data center, and the other is from outside of the data center. The internal contaminants are usually particles from air conditioning unit fan belt wear, toner dust, packaging and construction materials, human hair and clothing, and zinc whiskers from electroplated steel floor plates. The external sources of contamination include cars, electricity generation, sea salt, natural and artificial fibers, plant pollen and wind-blown dust.

 

Data Center Cleaning and Contaminants Prevention

Knowing where the dust and dirt come from, here offers some suggestions and Tip to reduce the contaminants.

 

Reduce the data center access. It is recommended that limit access to only necessary personnel can reduce the external contaminants.

Sticky mats should be used at the entrances to the raised floor, which can eliminate the contaminants from shoes largely.

Never unpack new equipment inside the data center, establish a staging area outside the data center for unpacking and assembling equipment.

No food, drink or smoking in the data center.

Typically all sites are required to have fresh air make-up to the data center, remember to replace on a regular basis.

Cleaning frequency depends on activity in the data center. Floor vacuuming should be more often is the traffic in the data center increased.

Inspect and clean the fiber optic components regularly, especially, fiber optic connector and interface of switched and transceivers.

The inside and outside of racks and cabinets should be cleaning.

 

Conclusion

Data center is the information factory today. It deals with numerous information and data. Data center cleaning is necessary. On one hand, If the “factory” is polluted by dust and dirt, how could it provide reliable and high quality services. On the other hand, data center cleaning can extend the life span of equipment and saving cost for both cooling and maintenance.

What is fiber to the x (FTTx)?

Fiber to the x (FTTx) is a collective term for various optical fiber delivery topologies that are categorized according to where the fiber terminates.

 

Optical fiber is already used for long-distance parts of the network, but metal cabling has traditionally been used for the stretches from the telecom facilities to the customer. FTTx deployments cover varying amounts of that last distance.

 

In an FTTN (fiber to the node or fiber to the neighbourhood) deployment, the optical fiber terminates in a cabinet which may be as much as a few miles from the customer premises. The cabling from the street cabinet to customer premises is usually copper.

 

 

In an FTTC (fiber to the curb or fiber to the cabinet) deployment, optical cabling usually terminates within 300 yards of the customer premises.

 

 

In an FTTB (fiber to the building or fiber to the basement) deployment, optical cabling terminates at the building, which is typically multi-unit. Delivery of service to individual units from the terminus may be through any of a number of methods.

 

 

In an FTTH (fiber to the home) deployment, optical cabling terminates at the individual home or business.

 

 

FTTP (fiber to the premises) is used to encompass both FTTH and FTTB deployments or is sometimes used to indicate that a particular fiber network includes both homes and businesses.

The FTTH Councils of Europe, North America and Asia-Pacific have agreed upon definitions for FTTH and FTTB. Standard definitions of the other terms have not yet been established.

Understanding Video SFP Transceivers

Video SFP transceivers are also referred to as digital video transceivers or SDI (short for Serial Digital Interface) video transceivers. They are designed to support SDI video pathological signal for SDI devices. Unlike SFP transceivers, video SFP transceivers are unfamiliar to many of us. Thus, this post will introduce video SFP transceivers in details for those who want to know this kind of transceiver.

 

Video SFP Transceivers VS SFP Transceivers?

Similar to SFP transceivers, Video SFP transceivers are small, hot-pluggable optics. The main difference of them is SFP transceivers are created to be used in data communication applications while video SFP transceivers are used to provide video transmission. As we all know, video transmission is different from data communication, one fundamental difference is that the video is transported in a uni-directional way. It means that the video link could be simply a signal fiber or coax signal transported. This reason has been the main driver to create different pinouts for the video SFP (as shown below). Thus, video SFP transceivers can have either two optical transmitters, two optical receivers or an optical transmitter and an optical receiver.

 

What Are the Categories of Video SFP Transceiver?

 

Video SFP transceivers can be classified into various categories according to different factors. For example, by operating wavelength, they can be divided into 1310nm, 1490nm, 1550nm and CWDM wavelengths video SFP transceivers; by operating rate, there are usually 3G-SDI, 6G-SDI and 12G-SDI video SFP transceivers.

 

3G-SDI video SFP transceivers has a data rate up to 3Gbps, which are specifically designed for robust performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates. They are generally used for television broadcasting. However, as technology advances, they are now also widely applied in global security applications such as high-end surveillance or unmanned systems, allowing simple designs or upgrades with full HD cameras.

 

6G-SDI video SFP transceivers’ data rate is intended to be twice as fast as 3G-SDI transceivers, which means it is supposed to deliver a payload of 6 Gbps. Therefore, they are not only designed for SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M and SMPTE 424M serial rates but also for SMPTE 2081. 6G-SDI video SFP transceivers are often used in camera, video, security monitoring applications and 4K /HDTV/SDTV service interfaces.

 

Speed up to 12Gbps, 12G-SDI video SFP transceivers are specifically designed for robust performance in the presence of SDI pathological patterns for SMPTE 259M, SMPTE 344M, SMPTE 292M, SMPTE 424M, ST2081 and ST-2082 serial rates. They are mainly used for SMPTE ST-297-2006, ST2081 and ST-2082 compatible electrical-to-optical interfaces and UHDTV/HDTV/SDTV service interfaces.

 

Conclusion

 

As 3G-SDI, 6G-SDI and 12G-SDI are all digital baseband signals, long-distance transmission on copper cable will definitely be limited. Thus, optic-fiber cables and 3G-SDI, 6G-SDI and 12G-SDI video SFP transceivers are perfect for long-distance video transmission.

Small Bend Radius Indoor Fiber Optic Cable

http://www.fiber-mart.com/special-fiber-patch-cables-polarization-maintainingpm-fiber-patch-cable-c-112_630_720.htmlWith the fast development of fiber optic communication technology and the trend of FTTX, indoor fiber optic cables are more and more required to be installed between and inside buildings. Typical indoor fiber optic cable types include GJFJV, GJFJZY, GJFJBV, GJFJBZY, GJFDBV and GJFDBZY. Compared with outdoor use fiber cable, indoor fiber optic cable experience less temperature and mechanical stress, but they have to be fire retardant, emit a low level of smoke in case of burning. And indoor fiber cables allow a small bend radius to make them be amendable to vertical installation and handle easily.

Most indoor fiber optic cables are tight buffer design, usually they consist of the following components inside the cable, the FRP which is non-metallic strengthen member, the tight buffer optical fiber, the Kevlar which is used to further strength the cable structure, making it resist high tension, and the cable outer jacket. The trend is to use LSZH or other RoHS compliant PVC materials to make the cable jacket; this will help protect the environment and the health of the end users. Usually the single mode indoor fiber optic cables are installed between the buildings where the distance is more than 100 meters, while multimode indoor fiber optic cables are used shorter distance connections. We supply SMF and MMF indoor fiber cables with various structures for different applications.

BASIC CABLE DESIGN

1 - Two basic cable designs are:

 

Loose-tube cable, used in the majority of outside-plant installations in North America, and tight-buffered cable, primarily used inside buildings.

 

The modular design of loose-tube cables typically holds up to 12 fibers per buffer tube with a maximum per cable fiber count of more than 200 fibers. Loose-tube cables can be all-dielectric or optionally armored. The modular buffer-tube design permits easy drop-off of groups of fibers at intermediate points, without interfering with other protected buffer tubes being routed to other locations. The loose-tube design also helps in the identification and administration of fibers in the system.

Single-fiber tight-buffered cables are used as pigtails, patch cords and jumpers to terminate loose-tube cables directly into opto-electronic transmitters, receivers and other active and passive components.

 

Multi-fiber tight-buffered cables also are available and are used primarily for alternative routing and handling flexibility and ease within buildings.

 

2 - Loose-Tube Cable

 

In a loose-tube cable design, color-coded plastic buffer tubes house and protect optical fibers. A gel filling compound impedes water penetration. Excess fiber length (relative to buffer tube length) insulates fibers from stresses of installation and environmental loading. Buffer tubes are stranded around a dielectric or steel central member, which serves as an anti-buckling element.

 

The cable core, typically uses aramid yarn, as the primary tensile strength member. The outer polyethylene jacket is extruded over the core. If armoring is required, a corrugated steel tape is formed around a single jacketed cable with an additional jacket extruded over the armor.

 

Loose-tube cables typically are used for outside-plant installation in aerial, duct and direct-buried applications.

 

 

 

3 - Tight-Buffered Cable

 

With tight-buffered cable designs, the buffering material is in direct contact with the fiber. This design is suited for "jumper cables" which connect outside plant cables to terminal equipment, and also for linking various devices in a premises network.

 

Multi-fiber, tight-buffered cables often are used for intra-building, risers, general building and plenum applications.

The tight-buffered design provides a rugged cable structure to protect individual fibers during handling, routing and connectorization. Yarn strength members keep the tensile load away from the fiber.

 

As with loose-tube cables, optical specifications for tight-buffered cables also should include the maximum performance of all fibers over the operating temperature range and life of the cable. Averages should not be acceptable.

Multimedia Modular Panel–Flexible Solution for Mixing Fiber and Copper Cabling

No matter we are constructing a copper network or a fiber optic network, inline coupler or fiber adapter always plays an important role in terminating or connecting between two lines. Now both copper networking and fiber optic networking technologies are being developed to meet the continuously increased bandwidth needs. And there are cases where we have to implement mixing fiber and copper link, such as link aggregation through EtherChannel or IEEE 802.3ad standards. Then how to effectively and efficiently couple both copper keystone jacks and fiber optic connectors on one panel? This post will provide the solution by using the multimedia modular panel, which can manage and organize a wide variety of fiber cabling and copper cabling.

 

Why Mixed Fiber and Copper Link?

At first, let’s have a glance at why there is a need for mixing fiber cables and copper cables. Ten years ago, people were asking if it was possible to have copper and fiber as part of the same port-channel group. And now, the term link aggregation is no longer new in constructing network architecture. And EtherChannel technology or IEEE 802.3ad both serves for link aggregation. Link aggregation combines multiple network connections in parallel in order to increase throughput beyond what a single connection could sustain, and to provide redundancy in case one of the links should fail. It groups a number of physical Ethernet links to create a single high-bandwidth data path. It can provide fault-tolerance and high-speed links between switches, routers and servers, and enhance the connection reliability and resilience. It is possible to aggregate copper ports for one link and fiber ports for the second link, but the important thing is to keep the two links at the same speed and as full-duplex. Under this circumstance, multimedia modular panel is designed to achieve the purpose.

 

Benefits of Blank Multimedia Modular Panel

When one link consists of both copper Ethernet patch cables and fiber optic patch cables, the blank multimedia modular panel makes a difference. For standard adapter panels with fixed ports, the patch cable that can be used is limited to one type. For example, every keystone patch panel can hold only one category style Ethernet patch cord, whether it is for Cat5e or Cat6 patch cables; and every preloaded fiber adapter panel can hold only one type of connector, such as single-mode LC APC duplex, LC UPC duplex, multimode SC APC duplex, etc. However, our blank multimedia patch panel is much flexible in copper and fiber mixed implementations. It allows users to aggregate up to six different types of ports at one time. These ports can be either copper or fiber. The inserted keystone jacks or inline couplers can be Cat6a, Cat6, Cat5e or Cat5. And the fiber optic adapters can be standard LC duplex, SC simplex and MTP/MPO. Users can install various port types on demand.

 

 

Moreover, it is very cost-effective as it may avoid port wasting. There are six blank ports on the panel. Generally, users can make use of all of them or deploy suitable number of adapters on it, so as to avoid waste of loaded ports.

 

 

In addition to these two major benefits to the users, multimedia modular panel also has some other good features. It has a two-tier design, and the cover plate on the rear can add mounting stability. Also plastic clips are optional for fiber adapter installation. It will be very easy to configure the snap-in modules on the panel. One bonus this modular panel can bring is that it is fitted with fiber-mart FHD fiber enclosures and cable management panels, which provides a clean, flexible and tidy cable managing for your network.

 

Conclusion

Blank multimedia modular patch panel allows customization of installation for multimedia applications requiring integration of fiber optic cables and copper cables. It is an ideal solution for a mixing copper and fiber link in some implementations. The flexible configuration it brings and cost-effectiveness it owns will no doubt make it a favorite in applications that require multiple port types. Every move, add, or change of coupler on it will be effortless. fiber-mart designed this multimedia modular panel for your convenience in fiber patching and cable management.
