10G SFP+ Transceiver Modules and Patch Cords Selection Guide

by www.fiber-mart.com

10G connection in telecommunication network is gradually moving from the backbone to layer 2 and layer 3. Both technology and market of 10G SFP+ transceiver modules are mature: the 10G transceiver modules have advanced from XENPAK which is the first generation of 10G transceiver to SFP+ which is now the most popular 10G optics. In addition, the price of 10G modules is getting lower. 10G modules are becoming affordable. Some genius guys even buy 10 SFP+ modules online to DIY private point to point 10G network. This article will offer basic information about 10G SFP+ transceiver modules and their connection instructions.

Basic of 10G SFP+ Transceiver Module

10G SFP+ transceiver has the same form factor of Gigabit SFP transceiver. Thus, many 10G modules can support 1/10G data rate to increase its flexibility during practical using. A SFP+ transceiver usually has two LC ports (as shown in the following picture). While 10G BiDi SFP+ transceiver, which transmitting and receiving signals from the same fiber optic cable, only has one LC port.

10G SFP+ transceiver and duplex patch cable

Except fiber optical transceivers, there are also various factory terminated copper-based or fiber optic based cables which are terminated with a SFP+ module on each end of the cable. There are mainly three types of these 10G cables: 10G SFP+ passive direct attached copper cable, 10G active direct attached copper cable and 10G SFP+ active optical cable. These 10G SFP+ cables eliminate the used of additional patch cable and can be directly plugged into the 10G SFP+ ports on switches. It is acceptable that these cables are an cost-effective and reliable solutions for 10G connections in short distance.

Optical Standards of 10G SFP+ Transceiver

According to IEEE standards, there are a variety 10GBASE SFP+ transceivers. For short distance transmission, 10GBASE-SR SFP+ and 10GBASE-LRM SFP+ can support transmission distance up to 300 meters and 220 meters over multimode fiber optic cables separately. 10GBASE-SR SFP+ modules is the most commonly used transceiver for short distance. It is suggested to work over wavelength of 850 nm.

There are a lot of 10G SFP+ transceivers that support long distance, like 10GBASE-LR SFP+, 10GBASE-ER SFP+, 10GBASE-ZR SFP+, CWDM SFP+, DWDM SFP+, BiDi SFP+, etc. These transceivers can support transmission distances ranging from 10 km to 120 km over single-mode fiber optic cables.

There is another special type of 10G transceivers which has been mentioned in this post, which is known as dual-rate SFP+. For example, dual-rate 1000BASE-LX and 10GBASE-LR SFP+ transceiver can be adjusted to support both 1G and 10G data rate up to 10 km over wavelength of 1310 nm.

10G BiDi SFP+ and simplex patch cable

Fiber Patch Cable Selection Guide for 10G SFP+ Transceivers

As 10G SFP+ DAC and AOC eliminate the using of additional patch cords. This part will introduce the selection guide for 10G SFP+ transceivers. During the selection of fiber optic patch cables for 10G SFP+ transceivers, the transmission distance is the first element to be considered. Single-mode patch cable is used for long distance transmission and multimode is designed for short distance transmission. Then the ports on the transceiver for receiving and transmitting should be considered. As mentioned, most 10G transceiver use duplex LC port, while BiDi SFP+ use simplex port (as shown in the above picture). Thus, simplex LC patch cords or duplex LC patch cords are used according to the port type on the transceiver. The following chart introduces detailed cabling information for 10G SFP+ transceivers.

Do You Know about SMF&MMF 40G QSFP+ Transceiver?

by Fiber-MART.COM

There is a growing need in the data center for upgrading from 10G to 40G switch connections due to server consolidation, virtualization, and performance improvements. However, for many data center operators this upgrade and conversion is more challenging based on two primary factors. First, the potential for a reconfiguration of the physical layer of the network based on the reduced reach of the OM3/OM4 multimode optics from 10GBASE-SR (300/400 m) to 40GBASE-SR4 (100/150 m) and second, the existing fiber optic cabling plant may need to be upgraded based on the additional fiber count needed to support the IEEE-defined 40GBASE-SR4 parallel optics. These two factors bring the SMF&MMF 40G QSFP+ transceiver to market.

What Is SMF&MMF 40G QSFP+ Transceiver?

As we all know, a fiber optic transceiver may either operate on multimode fiber (MMF) or single-mode fiber (SMF). However, a SMF&MMF 40G QSFP+ transceiver can be used with both MMF and SMF without the need for any software/hardware changes to the transceiver module or any additional hardware in the network. Usually, this transceiver is based on IEEE defined 40GBASE-LR4 specifications and operates in the 1310 nm band. It uses a duplex LC connector and supports distances up to 150 m over OM3 or OM4 multimode fiber and up to 500 m over single-mode fiber (different vendor may have different specifications). This is usually accomplished by combining four 10G optical channels at different wavelengths (1270, 1290, 1310, and 1330 nm) inside the transceiver module to transmit and receive an aggregate 40G signal over a single pair of multimode or single-mode fibers. At present, there are two main SMF&MMF 40G QSFP+ transceiver in the market. One is the Arista QSFP-40G-UNIV universal QSFP+ transceiver, and the other is the Juniper JNP-QSFP-40G-LX4 40GBASE-LX4 QSFP+ transceiver. These two types QSFP+ for both MMF and SMF are widely installed and used for upgrading from 10G to 40G networks without modification or expansion.

Advantages of SMF&MMF 40G QSFP+ Transceiver

With the increase in data center bandwidth requirements, migration to 40G for switch to switch connections is in higher demand. SMF&MMF 40G QSFP+ transceiver is designed to allow for seamless migrations from existing 10 to 40GbE networking without requiring a redesign or expansion of the fiber network. Besides, this transceiver also provides a cost-effective solution to migrate from multimode to single-mode fiber, allows a single-mode fiber infrastructure for distances up to 500m. The advantages of SMF&MMF 40G QSFP+ are as following.

Cabling Migrating from 10G to 40G

Existing 40G transceivers for short reach, QSFP+ SR4 and the extended reach QSFP+ CSR4, utilize four independent 10G transmitters and receivers for an aggregate 40G link, which use an MPO-12 connector and require 8-fiber parallel multimode fiber (OM3 or OM4). However, a SMF&MMF QSFP+ uses duplex LC connector, which is consistent with the existing 10G connections, which are also commonly MMF cables with duplex LC connectors. Therefore, a SMF&MMF QSFP+ allows the same cables to be used for direct 10G connections to direct 40G connections, resulting in zero-cost cabling migration.

Increase Number of 40G Links in the Network

As existing MMF 40G solutions need the use of 8 fibers for a 40G link, customers have to add additional fiber to increase the number of 40G links. By deploying the SMF&MMF 40G QSFP+ transceiver, customers increase the number of 40G links by 4 times without making any changes to their fiber infrastructure, which greatly expand network scale and performance.

Migrate from Multimode to Single-mode Fiber

As data rates increase from 40G to 100G and beyond to 400G, there is a strong desire for data centers to move to single-mode fiber for cost effectiveness. Due to the limitations of multimode transceivers to support existing distances with ever increasing data rates, migrating to 100G and 400G in the future will be simpler with single-mode fiber. However, the single-mode transceivers typically cost up to 4 times more compared to multimode transceivers. As SMF&MMF QSFP+ interoperates with 10km QSFP-LR4 optics, it s a cost effective solution for SM fiber infrastructure for distances up to 500 m.

Simplify the Data Centers with a Mix of MMF and SMF Deployments

The SMF&MMF 40G QSFP+ transceiver offers the unique advantage of operating on both multimode and single-mode fiber without any requirement for additional hardware or software. Customers can consolidate their optics and use SMF&MMF QSFP +in their network irrespective of the fiber type, which makes full use of the existing cabling systems, reduces the cost of deployment and of support, and simplify purchasing and deployments.

Conclusion

The SMF&MMF 40G QSFP+ transceiver enables data centers running at 10G today to seamlessly upgrade to 40G without having to re-design or modify the cable infrastructure, which allows organizations to migrate their existing 10G infrastructure to 40G at zero cost of fiber and to expand the infrastructure with low capital investment. It also offers a transition path for customer planning migrations to single-mode fiber in data centers with a single transceiver that bridges the gap between multi-mode and single-mode optics. With high-density 40G switches on hand, Fiberstore SMF&MMF 40G QSFP+ transceiver provides a cost-effective solution for migrating to next-generation 40G data center deployments.
