NVIDIA Mellanox® MFS1S50-H010V — HDR 200G → 2× HDR100 QSFP56 Active Optical Splitter, 10m
Technical Identity
The NVIDIA Mellanox® MFS1S50-H010V is a 10-meter LinkX Active Optical Cable (AOC) splitter from the MFS1S50 family. It is a hybrid breakout assembly: the switch end is 1× QSFP56 carrying 200Gb/s HDR, and the adapter side is 2× QSFP56 each carrying 100Gb/s HDR100. The cable is rated for InfiniBand HDR / HDR100 and for 200GbE / 100GbE Ethernet on supported NVIDIA Quantum-1 and Spectrum-2 platforms. Integrated 850 nm VCSEL optics over multi-mode fiber, permanently molded — no removable transceivers. Condition: New, factory-sealed.

What This Is NOT
NOT a 1-to-1 straight AOC. The MFS1S50-H010V is a hybrid splitter — 1× QSFP56 200G on the switch end fans out to 2× QSFP56 100G HDR100 on the adapter side. For 1-to-1 200G HDR, use the MFS1S00-Hxxx series.
NOT a passive copper DAC. Active optical cable with permanently integrated 850 nm VCSEL optics on each end; reaches farther than copper but cannot be re-terminated.
NOT a transceiver pair with a separate fiber jumper. Single molded cable assembly — optics are fixed at the factory.
NOT NDR / 400G / 800G capable. Maximum aggregate speed is 200Gb/s (HDR). For NDR 400G use the MFA7U series; for 800G NDR use OSFP cables.
NOT compatible with OSFP, QSFP-DD, QSFP112, or SFP cages. Both ends require QSFP56 (HDR / 200GbE) ports.
NOT a port-doubler on its own. The single 200G switch port must be placed in 2× HDR100 (HDR2X) split mode by the switch OS / subnet manager.
NOT bundled with adapters, switches, or rail kits — sold as a standalone cable.
Compatibility & Constraints
200G switch end — InfiniBand: NVIDIA Quantum-1 QM8700 / QM8790 HDR switches with the QSFP56 port configured in HDR2X (2× HDR100) split mode under the UFM / subnet manager.
200G switch end — Ethernet: NVIDIA Spectrum-2 SN3700 / SN3700C with the QSFP56 port set to 200GbE-to-2× 100GbE breakout in Cumulus / Onyx / SONiC.
100G adapter ends: NVIDIA ConnectX-5 Ex (VPI HDR100), ConnectX-6 (VPI HDR100), ConnectX-6 Dx (100GbE), or ConnectX-6 Lx (100GbE only) with QSFP56 cages. Each split tail occupies one adapter port on a separate or shared host.
Reach: 10m fixed length — intra-rack fan-out and adjacent-rack runs (e.g., ToR HDR switch → two HDR100 servers in the same or neighboring rack).
Power / thermals: Bus-powered through the QSFP56 cage; no external power. Lower copper loss and lighter cable bundle than DAC for dense ToR layouts.
Verify before deploying: switch firmware, port-split mode, subnet manager (for IB) or NOS profile (for Ethernet), and adapter firmware must all support HDR2X breakout. Mismatch typically results in only one of the two split tails linking.
Frequently Asked Questions (FAQ)
Q. What is the MFS1S50-H010V?
The MFS1S50-H010V is a 10-meter NVIDIA LinkX Active Optical Cable (AOC) splitter. It is a hybrid cable: the switch end is 1× QSFP56 at 200Gb/s HDR; the adapter side is 2× QSFP56 each at 100Gb/s HDR100. Rated for InfiniBand HDR / HDR100 and for 200GbE / 100GbE Ethernet on supported NVIDIA Quantum and Spectrum platforms.
Q. How does the MFS1S50-H010V splitter physically connect — what is on each end?
This is a hybrid splitter cable with 1× QSFP56 (200G HDR) on the switch side and 2× QSFP56 (100G HDR100) on the adapter side. Both ends use the QSFP56 form factor, but the single switch port is operated in 2× HDR100 (HDR2X) breakout mode and each of the two tails links one HDR100 / 100GbE endpoint.
Q. Which switches support 1× 200G to 2× 100G breakout with the MFS1S50-H010V?
For InfiniBand: NVIDIA Quantum-1 QM8700 / QM8790 HDR switches with HDR2X split enabled on the QSFP56 port. For Ethernet: NVIDIA Spectrum-2 SN3700 / SN3700C with the port configured at 200GbE → 2× 100GbE breakout. The split mode must be set in the switch OS or fabric manager before the cable will bring up both legs.
Q. Which adapters work on the two 100G split ends?
Any QSFP56-capable HDR100 or 100GbE adapter — NVIDIA ConnectX-5 Ex, ConnectX-6, ConnectX-6 Dx, or ConnectX-6 Lx (100GbE only) with a QSFP56 cage. Each split tail connects to one adapter port on a separate or shared host.
Q. Is the MFS1S50-H010V a passive DAC or an active optical cable?
Active Optical Cable (AOC). It uses 850 nm VCSEL optics over multi-mode fiber with permanently molded transceivers on each end. Reach is longer than passive copper DAC and the cable bundle is lighter, but the optics are fixed and not field-serviceable.
Q. What workloads is the 10m MFS1S50-H010V used for?
Typical uses: HPC compute fan-out from a 200G HDR top-of-rack switch port to two HDR100 servers, AI training cluster east-west fabric where 200G switch radix is doubled into 100G GPU servers, and high-density NVMe-oF storage links at 100GbE per server. The 10m length covers intra-rack fan-out and adjacent-rack runs.
