NVIDIA Mellanox MFS1S50-H030E 200Gb/s HDR Active Optical Splitter Cable, QSFP56 to 2×QSFP56, 30m, LSZH: This is a 30-meter active optical splitter cable (AOC) engineered for InfiniBand HDR fabrics. The MFS1S50-H030E (NVIDIA P/N 980-9I45C-00H030) splits a single 200Gb/s HDR QSFP56 link into two 100Gb/s HDR100 QSFP56 links. The cable is a fixed-length integrated assembly with VCSEL optics and is not a transceiver with a detachable patch cord. The jacket is LSZH for data center fire-safety compliance. This is a new (factory-sealed) unit.
Engineering Context
The MFS1S50-H030E enables a 1:2 fan-out from a single HDR-200 switch port to two HDR100 host adapters, doubling the effective port count of an HDR switch when paired with HDR100-class hosts. Active optical construction provides full EMI immunity and lower port-side weight than copper alternatives at this reach. The 30m length sits well above passive copper DAC budget, making AOC the practical choice for cross-row and inter-rack runs. The LSZH jacket emits minimal smoke and no halogens during a fire event, satisfying strict data-center cable regulations.
Deployment & Use Cases
1:2 port splitting from HDR Quantum switches (QM8700, QM8790) to HDR100 ConnectX-6 host adapters in HPC clusters. AI training fabrics where doubling effective port count reduces per-host fabric cost. Cross-row and inter-rack HDR connectivity exceeding passive copper reach. Storage-fabric interconnects in InfiniBand HDR-based parallel file system deployments.

Compatibility & Constraints
Compatible with NVIDIA Mellanox Quantum HDR switches (QM8700, QM8790) on the 200Gb/s side and ConnectX-6 HDR100 host adapters on the 2× 100Gb/s legs. Splitter mode must be configured on the switch port; some switch firmware levels require explicit per-port HDR→HDR100 split configuration. Not compatible with NDR (400Gb/s, QSFP56-DD or OSFP) or EDR-only (100Gb/s NRZ-only) ports. Not compatible with Ethernet-only switch SKUs without VPI / IB licensing. Fixed 30m length; not field-terminable or shortenable.
