Network operators are constantly faced with the challenge of optimizing the existing infrastructure of their network to meet the needs of their customers by offering more bandwidth. This scenario is true for every type of network, from FTTx networks to long-haul and transoceanic networks. Depending on bandwidth requirements and the amount of subscribers sharing the network costs, coarse wavelength division multiplexing (CWDM) has proven to be cost-effective for the ever-increasing mobile backhaul bandwidth and FTTx enterprise.

Today is Monday. And a new week began again. I am glad to be here and share some information about fiber optic transceivers. Recently, an old topic about compatible transceiver modules has been brought forward again in my community. Many users are still unsure that whether they should use the 3rd-party fiber optic transceiver modules in their switches. As we mentioned before, the 3rd-party compatible fiber optic transceiver modules cost much less than the origin brands’ which will help save much more on the their item budget. Thus, in general, out of consideration of saving cost, they would like to use. However, if you have the experience of using 3rd-party compatible fiber optic transceiver modules, you may find that sometimes it did not work as you expected. How to get out of this dilemma? How can we both save money and ensure the proper operation of work? In my opinion, to choose the right compatible fiber optic transceivers for your needs is the necessary precondition.

The ever-increasing need for higher data rate in mobile data traffic, data centers and cloud services has pushed the access streams from 2.5Gb/s to 100Gb/s, and is demanding for 100Gb/s beyond without a stop. In today’s core network that has deployed 100G rates, there are QSFP28 optical transceivers including SR4, PSM4, CWDM4, LR4, ER4, etc., serving for a maximum 25km transmission distance. And there are 100G AOC, DAC and breakout cables generally for applications of tens of meters. 100G CFP/CFP2 modules including SR10, LR4 and ER4 support transmission distances of 150m to 40km.

This hot-pluggable transceiver with SFP+ (Small Form Factor Pluggable Plus) footprint features duplex LC connector and provides up to 1.25 Gbps bi-directional data transfer rate. It supports transmission distances of up to 300 m (984.25 ft) for 62.5/125μm MMF and 500 m (1640.42 ft) for 50/125μm MMF fiber cabling.
