Q2B91040500F is a high performance QSFP28 transceiver module for 50 Gigabit Ethernet data links over a single mode fibre. The maximum reach is 40km. An internal DSP-based gearbox converts the 2 electrical input channels (each 25Gbbps NRZ) into one 25GBd PAM4 signal. The transmitter is a 1294nm laser generating the optical 25GBd output signal. The receiver is a 1308nm Avalanche Photodiode (APD) which detect the 25GBd PAM4 optical input signal. This 25GBd data stream is converted into two 25Gbps electrical output signals by the DSP. Consequently, a module with a 1308nm transmitter and a 1294nm receiver is required at the opposite side of the link. The recommended counterpart is Q2B19040500F. This transceiver module is compliant with the QSFP28 Multisource Agreement (MSA) and hot pluggable.
