This optical transceiver is based on 25G Ethernet IEEE 802.3cc standard. They are compliant with SFF-8402, SFF-8432, and SFF-8472, providing a fast and reliable interface for 25G Ethernet applications. The product implements digital diagnostics via a 2-wire serial bus and is compliant with the SFF-8472 standard.

The module consists of a microcontroller, inte- grated dual-clock data recovery function (CDR) laser drive and limiting amplifier, and a Transmitter and a Receiver. The microcontroller communicates with the host via a 2-wire serial communication interface, providing module control, status reporting and monitoring functions (DOM).

The laser driver amplifies the high-speed differential signal recovered from the TX CDR, and drives the laser to generate an optical signal, and maintains the stability of the transmitted optical power through an automatic optical power control feedback loop.
