Product Overview
The optical signals are multiplexed to a single-mode fiber through an industry standard LC connector. In the receive side, the four lanes of optical data streams are optically de-multiplexed by the integrated optical de-multiplexer. Each data stream is recovered by a APD and trans-impedance amplifier, retimed.
This QSFP28 100G ER4 module features a hot-pluggable electrical interface, low power consumption and MDIO management interface. It is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA) and compliant to IEEE 802.3bm.
