NVIDIA Mellanox InfiniBand HDR 200Gb/s to 2x100Gb/s QSFP56 Active Optical Splitter Cable 10m - MFS1S50-H010E
This active optical splitter cable is the NVIDIA Mellanox MFS1S50-H010E, a QSFP56-to-2xQSFP56 breakout AOC that splits a single 200 Gb/s InfiniBand HDR link into two independent 100 Gb/s HDR100 channels over a 10-meter reach. This is a refurbished unit, professionally tested and validated by T.E.S IT-SOLUTIONS. It is NOT a 1-to-1 cable, and it is NOT rated for Ethernet-only use (it is primarily an InfiniBand HDR cable).
Engineering Context
The MFS1S50-H010E uses VCSEL-based (850 nm) optics with PAM4 modulation across 4 multimode fiber (MMF) pairs on the single QSFP56 end, splitting to dual pairs on each of the two QSFP56 multiport ends. The aggregate 200 Gb/s HDR signal uses 4x50 Gb/s PAM4 lanes, which split into 2x(2x50 Gb/s) HDR100 channels. The cable is compliant with SFF-8665 for QSFP56 pluggable solutions. Each QSFP56 connector includes an EEPROM for product identification and status monitoring readable by the host system. The jacket is LSZH (Low Smoke Zero Halogen) for compliance with data center fire safety standards.
Deployment and Use Cases
The MFS1S50-H010E is deployed in InfiniBand HDR fabrics where a single 200 Gb/s switch port (such as on the NVIDIA Quantum QM8700 or QM8790) must connect to two separate HDR100 host channel adapters (such as the ConnectX-6 HDR100 MCX653105A-HDAT). This is the standard topology for 2:1 oversubscription in HPC clusters running MPI-based distributed computing and AI training workloads. The 10-meter reach covers rack-to-rack distances in structured cabling environments within compute pods.

Compatibility and Hard Constraints
The MFS1S50-H010E is designed for InfiniBand HDR infrastructure. It connects one 200 Gb/s HDR port to two 100 Gb/s HDR100 ports. It is NOT a 1-to-1 cable and cannot be used as a standard point-to-point link. It is NOT backward compatible with InfiniBand EDR (100 Gb/s) or FDR (56 Gb/s) equipment without explicit vendor validation. It requires QSFP56 ports on all three ends. The MFS1S50-H003E is the 3-meter variant, and the MFS1S50-H005E is the 5-meter variant. Compatible switches include the NVIDIA Quantum QM8700 and QM8790. Compatible adapters include the ConnectX-6 HDR100 series (MCX653105A-HDAT, MCX653106A-ECAT).
