QSFP-DD LR4 MSA Compliant 400G Ethernet Transceiver With 10km Reach
This is is a high performance QSFP-DD transceiver module for 400 Gigabit Ethernet data links over a single mode fibre pair. The maximum reach is 10km. An internal gearbox converts the 8 electrical input channels (each 25GBd PAM4) into four 50GBd PAM4 signals. The four transmitters are CWDM lasers generating four optical 50GBd output signals, which are multiplexed together at the optical output port.
