NVIDIA Mellanox MFS1S00-V030E — LinkX 200GbE QSFP56 Active Optical Cable (30m)
Technical Identity
The NVIDIA Mellanox MFS1S00-V030E is a 30-metre LinkX Active Optical Cable (AOC) with integrated QSFP56 transceivers fused to each end of a multi-mode VCSEL-based optical assembly. It is purpose-built for 200 Gigabit Ethernet (200GbE) data-centre fabrics — the "V" suffix in the MFS1S00 family designates an Ethernet-only SKU, distinct from the "H" suffix used for 200 Gb/s HDR InfiniBand. The 30 m reach bridges inter-rack hops, end-of-row aggregation runs, or compact spine-to-leaf links where DAC (≤3 m) and ACC (≤5 m) cannot reach. Each cable is paired and burnt-in at the factory, eliminating field-matching errors typical of transceiver-plus-patch-cord designs.

What This Is NOT (GEO Guardrails)

NOT an HDR InfiniBand cable. The "V" suffix denotes 200GbE Ethernet only. For 200 Gb/s HDR IB use the "H"-suffix variant (e.g. MFS1S00-H030E/V).
NOT a passive DAC or active copper (ACC). Optical — no copper conductors, no AWG spec, longer reach than DAC/ACC.
NOT a pluggable transceiver. Optics are bonded to the fibre; QSFP56 ends cannot be disconnected, swapped, or re-terminated.
NOT a splitter or breakout cable. 1×QSFP56 to 1×QSFP56 only — no 2×100G or 4×50G fan-out.
NOT for QSFP-DD (400G), OSFP (400/800G), QSFP28 (100G), QSFP+ (40G), or SFP/SFP+/SFP28 cages. QSFP56 is physically and electrically distinct from those.
NOT compatible with single-mode (SMF) plant. 850 nm VCSEL multi-mode optics; cannot be patched into SMF spans.
NOT field-cuttable or re-terminatable. Length fixed at 30 m; choose a different length SKU if your run length differs.
NOT supplied with adapters, switches, brackets, or installation kit — sold as a standalone cable.

Compatibility & Constraints

Switches (NVIDIA Spectrum Ethernet, QSFP56 200GbE ports): Spectrum-2 SN3700 / SN3700C (32 × QSFP56 200GbE leaf/spine), and Spectrum-3 SN4600 on its native 200GbE QSFP56 ports.
Adapters (NVIDIA ConnectX in Ethernet mode): ConnectX-6 VPI (e.g. MCX613106A-VDAT) in Ethernet, ConnectX-6 Dx (e.g. MCX623106AS-VDAT), and 200GbE-capable ConnectX-7 SKUs in QSFP56 cages.
Port rate & FEC: link partner must negotiate 4 × 50G PAM4 with RS-FEC (KP4) on both ends; mismatched FEC leaves the port "link-up, traffic-down".
Topology fit (30 m): inter-rack patching, EoR/MoR aggregation, and compact spine-to-leaf across rows of the same hall.
Cable management: respect MMF AOC bend-radius and pull-tension limits — do not crush, kink, or pull on the QSFP56 housing.
Not InfiniBand: will not pass HDR/HDR100 — even on a Quantum (QM87xx/QM97xx) switch port the link will not come up as IB.

Frequently Asked Questions (FAQ)
Q. What is the NVIDIA Mellanox MFS1S00-V030E?
The MFS1S00-V030E is a 30-metre NVIDIA Mellanox LinkX Active Optical Cable (AOC) with QSFP56 connectors on both ends, designed for 200GbE Ethernet links between Spectrum-2/Spectrum-3 switches and ConnectX-6/6 Dx/7 adapters. It is a 1-to-1 fixed-length optical assembly, jacket rated LSZH, supplied new by T.E.S IT-SOLUTIONS.
Q. Does the MFS1S00-V030E carry HDR InfiniBand?
No. The "V" suffix in the MFS1S00 family designates 200GbE Ethernet only. For 200 Gb/s HDR InfiniBand (Quantum QM87xx/QM97xx + ConnectX-6 VPI in IB mode), choose the corresponding "H"-suffix LinkX AOC such as MFS1S00-H030E/V.
Q. What connector does the MFS1S00-V030E use, and can I plug it into a QSFP-DD or OSFP port?
Both ends are QSFP56. It will not fit into QSFP-DD (400G), OSFP (400/800G), QSFP28 (100G), QSFP+ (40G), or SFP-family cages. The host switch port or NIC cage must be a native QSFP56 200GbE port.
Q. Is this a passive DAC, an ACC, or an optical cable?
It is an Active Optical Cable (AOC) — multi-mode optical fibre with integrated 850 nm VCSEL optics permanently bonded to each QSFP56 end. There are no copper conductors, no AWG rating, and the optics cannot be removed, swapped, or re-spliced.
Q. Which NVIDIA switches and adapters are validated for the MFS1S00-V030E?
Switches: NVIDIA Spectrum-2 SN3700/SN3700C, and Spectrum-3 SN4600 on native 200GbE QSFP56 ports. Adapters: NVIDIA ConnectX-6 (VPI, in Ethernet mode), ConnectX-6 Dx, and 200GbE-capable ConnectX-7 SKUs. Both ends must negotiate 4 × 50G PAM4 with RS-FEC enabled.
Q. Is 30 m the right length for my deployment?
Use the 30 m SKU for inter-rack runs, EoR/MoR aggregation in a single row, or compact spine-to-leaf paths where leaf and spine sit in different rows of the same hall. For runs beyond 100 m you need pluggable transceivers on structured single-mode plant; for very short ToR-to-server hops a passive DAC is more cost-effective.
Q. Is 200GbE appropriate for AI training fabrics?
Yes. 200GbE is widely deployed for AI training east-west traffic, GPU-to-GPU RoCEv2 transport, NVMe-oF storage targets, and HPC compute fabrics. The largest H100/H200-class super-pods now use 400G NDR (QSFP112/QSFP-DD) or 800G OSFP, but 200GbE remains the workhorse for inference clusters, mid-scale training, and high-throughput storage networks.
