40G QSFP+ SR4 100M MPO Optical Transceiver

Product Overview EQP294X-60D(I) is designed for 60km optical communication applications. 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 electric-absorption modulated 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 De multiplexed by an integrated optical De multiplexer. And passed on to an output driver, the receiver adopts APD. This module features a hot-pluggable electrical interface, low power consumption, and 2-wire serial interface.
