Q2C31040500F is a high performance QSFP28 transceiver module for 50 Gigabit Ethernet data links over a single mode fibre pair. The maximum reach is 40km. An internal DSP-based gearbox converts the 2 electrical input channels (each 25Gbps NRZ) into one 25GBd PAM4 signal. The transmitter is a CWDM laser generating the optical 25GBd output signal.
The receiver is an Avalanche Photodiode (APD) which detects the 25GBd PAM4 optical input signal. This 25GBd data stream is converted into two 25Gbps electrical output signals by the DSP.
This transceiver module is compliant with the QSFP28 Multisource Agreement (MSA) and hot pluggable.
