QSFP-40G-LR4 Duplex LC 40GBASE-LR4 1310nm 10km 40G QSFP+ LR4
The 100G QSFP28 LR4 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 (EMLs) 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 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.
