100Gbps QSFP28 ZR4

Optech's QSFP28 ZR4 is for 100 Gbps Ethernet applications. It is intended for use between data centers between switches, routers, trasmission equipment etc, and the optical distance is up to 80km over a SingleMode (SM) fiber.

The transceiver integrates the receiver and transmit path on one module. On the transmit side, four lanes of serial data (NRZ) are recovered by a CDR and passed to four laser drivers, which control four lasers with center wavelengths of 1296 nm,1300nm,1305nm and 1309nm. The optical signals are multiplexed to a single mode fiber through an standard LC connector. On the receiver side ,four lanes of optical data streams are amplified by an SOA, then the optical signal are de-multiplexed by an integrated optical demultiplexer. Each data stream is recovered by a PIN detector, then through the transimpedance amplifier and CDR pass to a CAUI-4 compliant output driver.
