100G CWDM QSFP28 Single Lambda

Teosco CWDM Single Lambda QSFP28 transceiver modules are designed for use in 100 Gigabit Ethernet links over 2km/10km on single mode fiber. They are compliant with the QSFP28 MSA, OIF CEI-28G-VSR and CAUI-4. The module incorporates one channel optical signal, on 1271, 1291, 1311 or 1331nm center wavelengths, operating at 100Gbps data rate. This module can convert 4 channels of 25Gbps (NRZ) electrical input data to 1 channel of 100Gbps (PAM4) optical signal, and also can convert 1 channel of 100Gbps (PAM4) optical signal to 4 channels of 25Gbps (NRZ) electrical output data. The electrical interface uses a 38-contact edge type connector. The optical interface uses a duplex LC connector. The high performance cooled EML transmitter and high sensitivity PIN receiver provides superior performance for 100 Gigabit Ethernet applications up to 2km/10km links. Digital diagnostics functions are available via the I2C interface, as specified by the QSFP28 MSA.
