A Brief Introduction To 100G Optical Modules

- Sep 19, 2019-

100G optical transceiver is a product to adapt the network market that develope from 10G to 40G and 100G. Transmission rate is 100Gbps. It plays a vital role in 100G network system constructing.

The types of 100G optical transceiver curentlly available on the market mainly include CXP, CFP, CFP2, CFP4 and QSFP28 transceiver.

100G Optical Transceiver


1. CFP optical transceiver supports full C-band wavelength adjustment, it can complete link detection. The CFP selects optical dual binary modulation pattern (ODB) for convenient deploying, power consumption is lower than 24W.

2. CFP2 optical transceiver is one-half size of CFP, which integration is twice times of CFP. It can achieve stable receiving sensitivity in a wide dynamic input range according to SOA. Power consumption is lower than 9W.

3. CFP4 transceiver is one-half size of CFP2, which integration is twice times of CFP2 and front panel port density is double compared with CFP2. CFP4 transceiver transmisson power is significantly imporved than CFP and CFP2, but power consumption has dropped significantly, which only about half of CFP2.

In addition, CFP4 transceivers complete 100G transmission by using four 25G channels, which has higher transmissisn power and strong stability.

4. QSFP28 transceivers is smaller than CFP4. Power consumption is less than 3.5W. 100G QSFP28 transceiver can be directly upgraded from 25G to 100G, and cost is more lower. 

Application of 100G optical transceivers

100G optical transceivers are used in Ethernet, synchronous fiber, optical transmission network, infinite broadband, etc..
