400G Base SMF LR4 OSFP Module Duplex LC Transmission on 10km for 5G Data Center

OSFP transceiver module is designed for use in 400 Gigabit Ethernet links over 10km single mode fiber. The module has 8 independent electrical input/output channels operating up to 53.125Gbps per channel.

The integrated GearBox in module converts the 8 channels of 53.125Gbps (PAM4) electrical input data to 4 channels of parallel optical signals, each capable of 106.25Gbps (PAM4) operation for an aggregate data rate of 400Gb/s. The four transmitter/receiver units operate on the ITU G.694.2 CWDM grid near 1300nm.

The transmitter path of the module incorporates a bi-directional PAM4 re-timer ASIC integrated with a 4-channels modulator driver, 4 externally modulated lasers and one optical multiplexer. On the receiver path, an optical de-multiplexer is coupled to 4 photodiodes, along with the PAM4 re-timer that built-in 4-channel TIA array.

The electrical interface of the module is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs, and compliant with OSFP MSA.
