25G SFP28 Module BIDI 20km 1270nm/1330nm LC DDM compatible with Cisco Switches
The SFP28 BIDI optical Transceiver integrates receiver and transmitter path on one module. In the transmit side,one of serial data streams are recovered, retimed and passed to laser driver. In the receive side, the optical data streams is recovered by a PIN and trans-impedance amplifier,retimed. This module features a hot-pluggable electrical interface, low power consumption.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the SFP28 and compliant to IEEE 802.3cc.
