Understand 100G Transceivers Transmission Principles

Changes to transmission speeds and expansion in data center capacities have driven the 100 Gigabit Ethernet. IHS Infonetics reports that by 2019, 100G Ethernet will make up more than 50 percent of data center optical transceiver transmissions. For 100G transceivers, there are 100GBASE-SR4, SR10 and PSM4 for short-distance transmission and 100GBASE-CWDM4, LR4 and ER4 for long-distance transmission.
 
100G Transceivers Transmission Principles
100GBASE-SR4 QSFP28 transceiver uses a 12-fiber MMF strand MTP/MPO cable for 100m connectivity (4 Tx and 4 Rx, each lane providing 25 Gbps of throughput over 850nm wavelength).

100GBASE-SR10 CFP optics use a 2×12-fiber or 24-fiber MMF strand MPO/MTP cable for 150m connectivity (10 Tx and 10 Rx, each lane providing 10 Gbps of throughput over 850nm wavelength).
 
100GBASE-PSM4 QSFP28 transceiver uses a 12-fiber SMF strand MTP/MPO cable for 500m connectivity (4 Tx and 4 Rx, each lane providing 25 Gbps of throughput over 1310nm wavelength).
 
100GBASE-CWDM4 QSFP28 transceiver provides aggregated 100G data rate over 2 km on SMF. The four optical signals from the four wavelengths are multiplexed and coupled to SMF through an industry-standard LC connector, and on the receive side, the demultiplexer splits the four wavelengths apart.
 
100GBASE-LR4 transceivers provide 100G data rate over 10 km on SMF. The four optical signals from the four wavelengths are multiplexed and coupled to SMF through an industry-standard LC connector, and on the receive side, the demultiplexer splits the four wavelengths apart.
 
Note: fiber-mart also provides Juniper compatible CFP LR4 modules with duplex SC interface.
 
100GBASE-ER4 transceivers provide 100G data rate over 40 km on SMF. The four optical signals from the four wavelengths are multiplexed and coupled to SMF through an industry-standard LC connector, and on the receive side, the demultiplexer splits the four wavelengths apart.
