The HG Genuine MQD-12F1C Transceiver is a high performance, cost effective module for serial optical data communication applications to 400Gbps, The MQD-12F1C is designed to Datacenter, accept 400G Ethernet protocol traffic for 70m links.

The module mainly consists of two parts: the transmitter part and the receiver part. The transmitter part consists of 8chs 850nm VCSEL array and driver. The receiver part consists of 8chs trans-impedance amplifier (TIA) and PIN photodiode array.

The high-speed electrical interface is based on low-voltage logic, with nominal 100ohm differential impedance, AC coupled inter of module.

Users can access to a series of registers to monitor and configurate data through two wire serial interface.
