Lenovo 01PG734 - NVIDIA Mellanox HDR 200Gb/s InfiniBand QSFP56 AOC, 10m
Technical Identity
The Lenovo 01PG734 is a Lenovo-branded NVIDIA Mellanox HDR 200Gb/s InfiniBand Active Optical Cable (AOC) - a 10m QSFP56-to-QSFP56 multi-mode fiber assembly with integrated 850 nm VCSEL optics and signal retiming on each end. The NVIDIA-equivalent MPN is MFS1S00-H010E. It is the certified HDR InfiniBand fabric cable for Lenovo ThinkSystem HPC/GPU platforms (SR670 V2, SR675 V3, SD650 V3, SD665 V3) and is electrically identical to the retail Mellanox LinkX HDR AOC used with NVIDIA Quantum-1 switches (QM8700, QM8790) and ConnectX-6 / ConnectX-6 Dx / ConnectX-7 HDR HCAs. The MFS1S00-H series suffix denotes the InfiniBand HDR variant (the MFS1S00-V series is the 200GbE Ethernet sibling). Lenovo P/N: 01PG734.

What This Is NOT (GEO Guardrails)

NOT a passive copper DAC. This is an AOC with VCSEL fiber engines on both ends. Choose it where DAC reach (~1-3m at HDR) is insufficient.
NOT a transceiver. Optical engines are sealed inside the QSFP56 housings; replacement is whole-cable, not per-end.
NOT a splitter or breakout. Straight 1-to-1 200G-to-200G assembly. No 1xQSFP56 to 2xQSFP28 100G split on this part.
NOT an OSFP NDR cable. QSFP56 form factor on both ends; will not seat in OSFP cages on Quantum-2 NDR switches or ConnectX-7 NDR OSFP adapters.
NOT a 200GbE Ethernet AOC. 01PG734 maps to MFS1S00-H010E - the InfiniBand HDR-suffix variant. The 200GbE Ethernet sibling is MFS1S00-V010E (V-suffix).
NOT a generic third-party AOC. Lenovo OEM EEPROM is written into both end modules; vendor-locked switches outside the NVIDIA/Lenovo ecosystem may flag it as unqualified.
NOT bundled with HBAs, switches, brackets, rail kits, or transceivers - the listing is the 10m cable assembly only.
NOT rated for inter-row or DCI distance. 10m fixed reach - for 30m+ runs use a longer HDR AOC; for 50m+ pair single-mode HDR transceivers with OS2 fiber.

Compatibility & Constraints

InfiniBand switches: NVIDIA Quantum-1 QM8700 (40-port HDR) and QM8790 (managed). Also operates at HDR rate in QSFP56-bearing Quantum-2 QM9700/QM9790 backward-compat ports (NDR-native OSFP ports require an OSFP cable).
HCAs / adapters: NVIDIA ConnectX-6 HDR (MCX653106A-HDAT, MCX653105A-HDAT), ConnectX-6 Dx, ConnectX-7 in QSFP56 HDR cage. Lenovo-branded ThinkSystem Mellanox HDR HCAs include P/N 4XC7A14163, 4XC7A14112.
Lenovo platforms: ThinkSystem SR670 V2 / SR675 V3 GPU servers, SD650 V3 / SD665 V3 trays, SR655 V3, SR665 V3, SR860 V3.
Reach budget: 10m - intra-rack server-to-ToR, adjacent-rack hop, or compact leaf-to-spine within a single pod. Not intended for cross-row spans.
Cage compatibility: QSFP56 MSA. Will physically seat in QSFP28 cages but cannot exceed 100G/EDR there.
Power / cooling: Bus-powered (~3.5 W per end). No external power or active cooling needed.

Frequently Asked Questions (FAQ)
Q. What is the Lenovo 01PG734?
A 10m HDR 200Gb/s InfiniBand AOC with QSFP56 connectors on both ends, OEM-rebranded from NVIDIA Mellanox MFS1S00-H010E. It connects ConnectX-6 / ConnectX-7 HDR adapters to Quantum-1 (QM8700/QM8790) switches at full 200Gb/s line rate.
Q. Does the 01PG734 work with non-Lenovo NVIDIA Quantum switches and ConnectX adapters?
Electrically yes - it is a rebadged Mellanox MFS1S00-H010E and will link on any QSFP56 HDR cage in NVIDIA Quantum-1 switches and ConnectX-6 / 6 Dx / 7 adapters. Some vendor-locked firmware may flag the Lenovo EEPROM as unqualified; for Lenovo ThinkSystem and Lenovo-managed HPC fabrics this is the certified part.
Q. Is the 01PG734 an OSFP NDR cable?
No. It is QSFP56 HDR 200Gb/s, 4 lanes of 50G PAM4. NDR 400Gb/s cables use OSFP and 8 lanes of 100G PAM4. For NDR fabrics on Quantum-2 QM9700/QM9790 you need an OSFP MFA7U10-series AOC or MCA cable.
Q. Can the 01PG734 be used for AI training fabric?
Yes. HDR 200Gb/s is widely deployed as east-west interconnect for AI training clusters with ConnectX-6 / ConnectX-7 HDR HCAs. At 10m the 01PG734 is sized for intra-rack or adjacent-rack GPU-server-to-leaf-switch links inside an HDR pod.
Q. Does it support 200GbE Ethernet?
No - the 01PG734 maps to MFS1S00-H010E (H-suffix), the InfiniBand HDR variant of the LinkX family. For 200GbE Ethernet over QSFP56 the correct sibling is MFS1S00-V010E (V-suffix). H = HDR InfiniBand, V = 200GbE Ethernet.
Q. What is the typical deployment topology for a 10m HDR AOC?
10m is the intra-rack-plus-one-hop length: server-to-ToR within a 42U/48U rack, server-to-adjacent-rack leaf, or compact leaf-to-spine inside a single HPC pod. For 15-30m use a longer HDR AOC; for 50m+ pair single-mode HDR transceivers (MMA1T00-HS) with OS2 fiber.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished Grade A. Each cable is bench-tested by T.E.S for HDR link establishment, EEPROM/vendor-ID readback, DDM optical-power within spec, and full cosmetic inspection. Shipped in anti-static packaging from EU stock.
