400-Gbps QSFP-DD SR8 Optical Transceiver Module with Quad Small Form-Factor Pluggable Double Density (QSFP-DD) form-factor is of high performance in bi-directional signal transmission and aggregate 400Gbps bandwidth, which design to follow QSFP DD MSA.

With integrated drivers, 400G QSFP-DD SR8 minimizes the IC count, allowing the optical chip to be positioned further from high-temperature, high-power ICs. This ensures that the optical chip can be up to 33.56mm away from the DSP center, reducing the LD chip temperature by 10-20 degrees during extended use in high-temperature conditions. This not only guarantees a longer service life but also enhances the reliability of optical chips and 400G QSFP-DD SR8 optical transceivers.
