1310nm 40km DOM LC SMF Optical Transceiver Module
Functional Description
Olinkcom’ OLSQXXTXM-CD40 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
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.
