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

The integrated GearBox 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.

• Supports 425Gbps data rate
• Single 3.3V Power Supply
• Up to 10km transmission over Single Mode Fiber with KP4 FEC
• Duplex LC connector
• 8x53.125Gbps (PAM4) electrical interface
• PIN and TIA array on the receiver side
• Power dissipation < 8W
• Case temperature range: 0°C to 70°C (commercial)

• 400G Ethernet networks
• 400G-LR4 applications
• Data center infrastructure
• InfiniBand systems

The four transmitter/receiver units operate on the ITU G.694.2 CWDM grid near 1300nm. The transmitter path incorporates a bi-directional PAM4 re-timer ASIC integrated with a 4-channel 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 includes a built-in 4-channel TIA array. The electrical interface is compliant with the 400GAUI-8 interface as defined by IEEE 802.3bs and OSFP MSA standards.
