100Gb/s QSFP 28 ER4 40KM 1296/1300/1305/1309 nm Optical Transceiver Module

Short Description:

BD-QSFP28-CD40 100G optical transceiver integrates the transmit and receive path onto one module. On the transmit side, four lanes of serial data streams are recovered, retimed,and passed on to four laser drivers, which control four lasers (Lan-WDM) 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 optical data streams are optically demultiplexed by an integrated optical demultiplexer. Each data steam is recovered by a APD photodetector and transimpedance amplifier, retimed, and passed on to an output driver. This module features…
