NVIDIA Mellanox MFS1S90-H003E Active Fiber Splitter Cable, HDR InfiniBand, 200Gb/s to 2x 200Gb/s, QSFP56, 3m, LSZH: This enterprise networking cable is a 3-meter active optical splitter cable that breaks out a single HDR 200Gb/s InfiniBand QSFP56 port into two independent HDR 200Gb/s QSFP56 connections, part number MFS1S90-H003E. The cable uses active fiber optics and LSZH (Low Smoke Zero Halogen) jacket material. This is a new unit.
Engineering Context
The MFS1S90-H003E enables HDR InfiniBand breakout from a single 200Gb/s port to two 200Gb/s links, effectively doubling port utilization on HDR switches that support breakout mode. As an active optical cable, it contains laser transceivers at each end, requiring power from the QSFP56 ports (typically 3.5W per connector). The active design supports longer distances than passive copper while maintaining signal integrity at HDR data rates of 50 Gb/s per lane (4 lanes per 200Gb/s link). The LSZH jacket meets datacenter fire safety requirements (IEC 60332-1) by producing minimal smoke and no halogen compounds if exposed to flame. The 3-meter length supports intra-rack and adjacent-rack connections in HPC clusters.
Deployment & Use Cases
HDR InfiniBand fabric breakout in HPC and AI training clusters running NCCL or MPI workloads. Connecting HDR switches (e.g., NVIDIA QM8790 series) to dual HDR host channel adapters. Maximizing port utilization on HDR InfiniBand leaf switches with breakout capability. GPU-to-GPU interconnect in NVIDIA DGX or HGX systems with HDR InfiniBand fabric. Datacenter environments requiring LSZH-rated cabling for fire safety compliance (EN 50575 / IEC 60332).

Compatibility & Hard Constraints
InfiniBand HDR Only: This is an HDR InfiniBand cable. It does not support Ethernet. For Ethernet breakout cables, different part numbers are required. QSFP56 Ports Required: All three connectors are QSFP56. Not compatible with QSFP28, QSFP-DD, or OSFP ports. Active Cable: Requires power from the host QSFP56 port (~3.5W). Will not function if the port does not supply adequate power. HDR Speed Tier: Designed for HDR (200Gb/s). Not backward-compatible with EDR (100Gb/s) or FDR (56Gb/s) fabrics. Splitter Cable: This is a 1-to-2 breakout. The switch port must support breakout mode configuration in subnet manager.
