QSFP28-100G-LR4 Duplex LC 100GBASE-LR4 1310nm 20km 100G QSFP28 LR4
The 100G QSFP28 20km optical transceiver integrates the transmit and receive path onto one . 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 features a
-pluggable electrical interface, low power consumption, and 2-wire serial interface.
