The 400G QSFP-DD to 2xQSFP56 active optical splitter cable connects a single 400G QSFP-DD port to two independent 200G QSFP56 ports, carrying 8 lanes of 50Gb/s PAM4 (26.5625G Baud/lane) over OM3/OM4/OM5 multimode fiber. It supports link distances of up to 70m on OM3 and 100m on OM4 or OM5, making it well suited for connecting newer 400G switch uplinks down to existing 200G server, NIC, or storage infrastructure.

The cable is compliant with QSFP-DD MSA, 400GBASE-SR8, and 200GBASE-SR4 (IEEE 802.3cd), and provides digital diagnostics over I2C per CMIS V4.0 — covering per-lane transmit/receive optical power monitoring alongside module-level voltage and temperature. Both ends use uncooled 850nm VCSEL arrays and PIN photodetector arrays, and the cable is rated for a minimum fiber bend radius of 30mm to protect signal integrity during rack cabling.
