by Fiber-MART.COM

In the last paper we discuss the "FAQ we need to know about Gigabit Ethernet Transceiver Modules", and in this paper we are going to talk atout 10Gigabit Ethernet fiber optic transceiver.

 

Q:What are the main types of Transceiver Module?

 

A:Transceiver modules are available in various form factors, and can be optical (fibre optic) or designed for copper wiring. Different transceiver modules support different data rates, from 100Base (100 Mbit/s) up to 100GbE (100 Gbit/s). There are some common types of transceiver modules as the following:

 

 

Gigabit interface converter (GBIC) : 1 Gigabit EthernetTypes of Transceiver Module

 

XENPAK : 10 Gigabit Ethernet

 

X2 : 10 Gigabit Ethernet

 

Small form-factor plable (SFP) : 1 Gigabit Ethernet, also known as the Mini-GBIC

 

Small form-factor plable (SFP+) : 10 Gigabit Small Form Factor Plable

 

XFP : 10 Gigabit Small Form Factor Plable (slightly larger than the SFP+)

 

Quad Small Form-factor Plable Plus (QSFP+) : 40 Gigabit Ethernet

 

C Form-Factor Plable (CFP) : 40 – 100 Gigabit Ethernet

 

 

Q:What tools do I need when installing a Transceiver Module?

 

A:The following is a list of the tools which are recommended when installing a Transceiver module:

 

 

A Wrist strap or similar personal grounding device designed to stop ESD occurrences.

 

An Antistatic mat or similar which the transceiver can be placed on.

 

Fibre-optic end-face cleaning tools and inspection equipment.

 

A flat head screw driver is require to install a XENPAK transceiver module.

 

 

Q:What are CWDM and DWDM Transceiver Modules?

 

A:Wavelength-division multiplexing (WDM) is a technology which multiplexes a number of optical carrier signals onto a single optical fiber by using different wavelengths (i.e., colors) of laser light. WDM is divided into different wavelength patterns, conventional/coarse wavelength-division multiplexing (CWDM) and dense wavelength-division multiplexing (DWDM). In general, a CWDM (coarse WDM) MUX/DEMUX deals with small numbers of wavelengths, typically eight, but with large spans between wavelengths (spaced typically at around 20nm). A DWDM (dense WDM) MUX/DEMUX deals with narrower wavelength spans (as small as 0.8nm, 0.4nm or even 0.2nm), and can accommodate 40, 80, or even 160 wavelengths. CWDM and DWDM transceiver modules are the transceiver modules which are combined the CWDM or DWDM technology. The main advantage of both CWDM and DWDM is that they allow you to expand your networks capacity without the need for physical fibre optic cabling. Click and see 1GB DWDM transceiver price.

 

Q:What is DOM support?

 

A:DOM, short for Digital optical monitoring, is a feature which allows you to monitor many parameters of the transceiver module in real-time. DOM allows you to monitor the TX (transmit) and RX (receive) of the module, as well as input/output power, temperature, and voltage. Network administrators can then check and ensure that the module is functioning correctly.

 

Q:What is a ‘Red’ (RGD) Transceiver Module?

 

A:You may be interested in the “-RGD” in the product number of some transceiver module. In fact, these are enhanced transceiver modules which have been designed for greater durability, and can operate under more extreme conditions. Red transceivers may feature enhanced ESD protection, and extended operating temperature range.

 

Q:What are the main types of 10 Gigabit Ethernet SFP+ Modules?

 

A:10 Gigabit Ethernet is 10 times faster than gigabit Ethernet, with a data rate of 10 Gbit/s which is defined by the IEEE 802.3ae-2002 standard. The following list shows us fibre SFP module 10G types.

How to Use Field Assembly Connector?

by Fiber-MART.COM

The expansion of FTTH application has brought prosperity to the manufacturing of field assembly connectors for fast field termination. This type of connector gains its popularity due to the applicability to cable wiring and compact bodies which are easily stored in optical fiber housings. With excellent features of stability and low loss, field assembly connector has now become a reliable and durable solution for fiber optic systems. However, do you really know the field assembly process of the connector? This article provides an easy guide to show you the way of using field assembly connector.

Introduction to Field Assembly Connector

Before getting to know the instruction process, let’s have a look at the basic knowledge about field assembly connector. Field assembly connector or fast connector is an innovative field installable optical fiber connector designed for simple and fast field termination of single fibers. Without using additional assembling tools, field assembly connector can be quickly and easily connected to the drop cable and indoor cable, which saves a lot of required termination time. It is specially designed with the patented mechanical splice body that includes a factory-mounted fiber stub and a pre-polished ceramic ferrule. Field assembly connector is usually available for 250 µm, 900 µm, 2.0 mm and 3.0 mm diameter single-mode and multimode fiber types. The whole installation process only takes about 2 minutes which greatly improves the working efficiency.

Internal Structure of Field Assembly Connector

From the following figure, we can see the specific internal structure of field assembly connector. The ferrule end face of the connector is pre-polished in a factory for later connection with the fiber. A mechanical splice is also formed at the end of the ferrule for mechanical fixation of optical fiber. The mechanical splice consists two plates, one with a V groove, another with flat surface above the V groove, and a clamp for the insertion of the two plates. When inserting the fiber, a wedge clip will keep the V groove open for easier installation. After the fiber insertion, the wedge clip can be extracted from the V groove.

Field Assembly Instruction Guide

Although it is an simple way to use field assembly connector, the right operation process is also important. Here will introduce some basic steps for connector installation.

Step 1, prepare the field assembly connector parts and related tools required during the process. There is no need for special tools, but fiber cleaver and jacket stripper are still necessary.

Step 2, insert the connector boot into the fiber cable.

Step 3, cut and reserve 10mm bare fiber by fiber cleaver and then make sure the total fiber length of 30 mm.

Step 4, insert the fiber from bottom until the stopper and make fiber present micro bend.

Step 5, press the press cover to tight the bare fiber.

Step 6, lock the boot with yarn.

Step 7, cut the yarn.

Step 8, screw the boot and put on housing to complete assembly.

Precautions

Here are some precautions for you to notice during the process:

Point 1, the product is sensitive to dirt and dust. Keeping it away from any possible contamination is necessary.

Point 2, the performance will be influenced by the fiber cutting surface condition. Use a cutter with a sharp blade for the best results.

Point 3, insert the fiber into the connector slowly. If the fiber is roughly inserted, it might be damaged or broken, leading to failure of connector installation. Broken fiber could scatter in all directions.

Point 4, do not remove the dust cap until the connector has been completely assembled in order not to cause a high insertion loss.

Point 5, a proper amount of index matching gel is applied in the connector. Do not insert fiber more than once into connector.

Conclusion

Fiber assembly connector enables quick termination to improve reliable and high connector performance in FTTH wiring and LAN cabling systems. All the above solutions provided by fiber-mart.COM are available to meet your requirements. Please visit the website for more information.

THE DIFFERENCES BETWEEN CABLE AND FIBER OPTIC BROADBAND

When it comes to broadband internet connections, most people value speed. They want to be able to access the internet and transmit data as quickly as possible. Moreover, in order to do this, people typically rely on either cable or fiber optic broadband service. However, what many people don’t realize is that there are notable differences between the two:

 

CABLE VS. FIBER OPTIC BROADBAND

Fiber optic broadband relies on fiber optic cables to move data around. Fiber optics cables are known for being capable of moving information very quickly, and they are much more reliable than other types of cables. Cable broadband, despite its name, also relies on fiber optic cables to move data around. This can be a little bit confusing for some people to understand, but cable broadband is quite similar to fiber optic broadband in this way.

 

What sets the two broadband services apart is how they actually connect to your home. There are some fiber optic broadband providers that do it with fiber optic cables, but for the most part, fiber optic broadband companies use copper phone lines to connect to your home. Fiber optic cables run to street cabinets and carry data there before copper phone lines finish the job. Cable broadband, on the other hand, utilizes coaxial cables to create a connection between the cabinet and your home rather than copper phone lines. Coaxial cables are known to be a lot faster than copper phone lines when it comes to transmitting data.

 

Cable and fiber optic broadband are both incredibly fast, but before you choose one over the other, it’s important to understand how they work. It’s also important to remember that they both use fiber optic cables for the most part, which proves just how vital fiber optic cables are to communications today.

Les principaux connecteurs

Le connecteur SC est le plus employé actuellement. On le retrouve sur un grand nombre d’équipements actifs quelle que soit l’application (Ethernet, Fiberchannel…). Il présente de nombreux avantages par rapport aux connecteurs ST : dépassement moindre de l’embout donc pas de risque de pollution, conception “pull-proof” donc pas de risque de déconnexion lors d’une traction sur le câble, section rectangulaire pour une meilleure prise en main et un guidage amélioré à l’intérieur du raccord. Il répond à la norme CEI 60874-14 et porte la dénomination SC (“Subscriber connector”).

 

Le connecteur bi-fibre LC dispose d’embouts de céramique de 1,25 mm et de corps plastique. Les fibres sont espacées de 6,25 mm. Développé par AVAYA, il permet de réduire de moitié la taille des connecteurs existants, tout en conservant des technologies éprouvées. Il répond à la norme CEI 61754-20 et porte la dénomination LC.

 

MPO signifie « Multiple-fiber Push On/Push Off ». C’est une solution permettant d’augmenter la densité du câblage fibre optique en s’appuyant sur un connecteur multi-fibre standardisé.Chaque connecteur intègre 12 fibres optiques et est assemblé sur un câble fibre optique pour former une jarretière MPO qui peut remplacer avantageusement les liaisons pré-connectorisées classiques ou les pigtails.

 

Le MPO est une solution plug-and-play qui permet un déploiement rapide, et ne nécessite pas d’outils d’assemblage.

Le connecteur ST rappelle les fiches BNC ; le verrouillage s’effectue par quart de tour de la bague externe. Proposé par tous, le connecteur ST est devenu un standard. Il répond à la norme CEI 60874-10 et porte la dénomination BFOC 2.5.
