Why should Data Centers Deploy QSFP-DD 400G FR4?

With the development of optical communication technology, the market size of optical modules continues to grow. 400G QSFP-DD packaging has become one of the most popular optical modules for hyperscale data centers due to its advantages of low power consumption, small size and high speed.

At present, the types of 400G QSFP-DD optical modules on the market include 400G SR8, 400G DR4, 400G FR4, 400G LR4, 400G LR8, etc.

Today we introduce YXFiber's YXF-QDD-400G-FR4. It is a transceiver module designed for 2 km optical communication applications and complies with the 100G Lambda MSA standard. The module can convert 8 channels of 53.125 Gbps electrical data into 4 channels of 106.25 Gbps optical signals and multiplex them into a single channel for 425 Gbps optical transmission. Likewise, it optically demultiplexes the 425 Gbps input into 4-channel signals and converts them into 8-channel output electrical data at the receiver end. It is designed to meet the most severe external operating conditions, including temperature, humidity, and EMI interference. The module offers very high functionality and feature integration, which can be accessed through an I2C interface.
