In the context of the continuous progress of Internet technology and the increasing demand for network transmission speed, 400G FR4 optical module came into being and has become the key to meet the needs of high-speed network transmission in the future. This article describes the features, advantages, and application scenarios of the 400G FR4 optical module in detail.

I. Working principles of the 400G QSFP-DD FR4 optical module

The 400G QSFP-DD FR4 optical module is an optical transceiver module designed for 2km optical communication applications and complies with the 100G Lambda MSA standard. The module can convert 8 53.125Gb/s electrical signals into 4 106.25Gb/s optical signals, and reuse them into one optical signal for 425Gb/s optical transmission.

Similarly, it can optically demultiplexed 425Gb/s input to a 4-channel signal, converting it to 8-channel output electronic data at the receiving end. It is designed to meet the harshest external operating conditions, including temperature, humidity and electromagnetic interference. The module uses a duplex LC interface that provides a very high level of functionality and functional integration, accessible via a two-wire serial interface.
