QSFP56 200Gb/s LR4 Transceiver

The QF56-QG200-10 optical transceiver integrates the transmit and receive path onto one module. On the transmit side, four lanes of PAM-4 data streams are passed on to four laser drivers, which control four DFB lasers with 1296, 1300, 1305, and 1309 nm center wavelengths. The optical signals are then multiplexed into a single-mode fiber through an industry-standard LC connector. On the receive side, four lanes of PAM-4 optical data streams are optically demultiplexed by an integrated optical demultiplexer. Each data steam is recovered by a PIN photodetector and transimpedance amplifier, retimed and passed on to an output driver. This module features a hot-pluggable electrical interface, low power consumption, and 2-wire serial interface.
