Sky Optics 400G QSFP-DD SR4.2 BiDi optical transceiver complies with official 400GBASE-SR4.2 industrial standard with unique Tx850nm/Rx908nm bidirectional VCSEL design. The module outputs total 425Gbps bandwidth and supports 70m(OM3)/100m(OM4)/150m(OM5) transmission via MPO12 connector, and supports electrical fan-out into 4 independent 100G SR1.2 channels.

Optimized circuit design keeps its power consumption under 8.5W, supporting stable operation at 0℃-70℃. It is equipped with full DDM monitoring and CMIS4.0 compatibility, and the innovative BiDi dual-wavelength design halves on-site fiber usage, greatly reducing project costs and cabinet space occupation. All products undergo strict aging tests to ensure stable performance.

Tailored for 100G-to-400G hybrid network upgrade, this module adapts to IDC renovation, cloud campus cabling and HPC cluster interconnection scenarios. It avoids large-scale fiber replacement, serving as an efficient and cost-effective upgrade solution for global data center networking projects.
