100G QSFP28 Optical Fiber Transceiver Duplex Lc 1310NM 10KM DDM
100G-QSFP28-LR4
Description
The 100G QSFP28 LR4 optical receiver integrates receive path onto one module. The receiver four lanes of 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.
