Description
ETSC’s OM3660FX102 is a transceiver module designed for 2 km optical communication applications, and it is compliant with 100G Lambda MSA standard. This module can convert 8-channel 53.125 Gbit/s electrical data to 4-channel 106.25 Gbit/s optical signals, and multiplex them into a single channel for 425 Gbit/s optical transmission. Similarly, it optically de-multiplexes a 425 Gbit/s input into 4- channel signals, and converts them to 8-channel output electrical data on the receiver side. It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.
