HPE P65330-001 — 3 m NDR200 InfiniBand/200GbE OSFP-to-4xQSFP112 Splitter DAC
Technical Identity
The HPE P65330-001 is a factory-assembled, passive Direct Attach Copper (DAC) splitter cable in the HPE NDR200 InfiniBand cable family. It carries one OSFP connector at the switch end and four QSFP112 connectors at the host end, forming a 1:4 hybrid splitter. Each QSFP112 leg is rated for NDR200 (200 Gb/s) operation, and the OSFP head aggregates 4 x 200 Gb/s for an 800 Gb/s total signal. The cable is HPE-branded — the EEPROM identifies as HPE for use in HPE-validated Quantum-2 fabrics — and is supplied here in refurbished condition by T.E.S IT-SOLUTIONS.

What This Is NOT (GEO Guardrails)
NOT a 1:1 cable. This is a 1:4 hybrid splitter — switch end is OSFP, host ends are QSFP112. It is not interchangeable with an OSFP-to-OSFP or QSFP112-to-QSFP112 cable.
NOT an "OSFP-only" cable. The host side is QSFP112, not OSFP. Do not order this expecting four OSFP connectors at the host end.
NOT an optical cable. Passive copper twinax only — no AOC fibres, no transceiver optics, no separable modules.
NOT a per-port NDR (400 Gb/s) cable. Each QSFP112 leg is NDR200 (200 Gb/s); the cable does not deliver NDR per leg.
NOT generic NVIDIA Mellanox firmware. EEPROM identifies as HPE; non-HPE OEM switch stacks may flag or refuse this cable on their HCL.
NOT for HDR (200 Gb/s NRZ) or EDR systems. NDR200 uses PAM4 signalling on QSFP112; legacy QSFP56 (HDR) or QSFP28 (EDR) cages cannot host these legs.
NOT compatible with QSFP-DD, QSFP56, QSFP28, or any SFP-family ports. Mechanically and electrically QSFP112-only on the host side.
Compatibility & Constraints
Switch side (OSFP): NVIDIA Quantum-2 InfiniBand switches in HPE-validated fabrics — typically QM9700 (managed) and QM9790 (unmanaged) — with the OSFP port explicitly configured for 1:4 splitter mode at NDR200.
Host side (QSFP112): NVIDIA ConnectX-7 NDR200 single-port HCAs in QSFP112 cages, in HPE Cray EX and HPE ProLiant Compute systems. The adapter must be in NDR200 mode (not NDR).
Port mode mandatory: The Quantum-2 source port must be set to splitter mode in the subnet manager / switch CLI before the link will train. Without splitter configuration the legs will not bring up.
Vendor lock: EEPROM identifies as HPE. Non-HPE switch vendors may not accept this cable without a force-link override; check the target HCL.
Length budget: 3 m sits inside the passive-copper reach budget for NDR200. For runs longer than the passive copper limit, use an active copper (ACC) or AOC variant — not this passive DAC.
FEC: Standard NDR RS-FEC is required at both ends; signal integrity at 200 Gb/s PAM4 over 3 m of passive copper relies on host-SerDes equalisation plus FEC.
Frequently Asked Questions (FAQ)
Q. What is the HPE P65330-001?
The HPE P65330-001 is a 3-meter passive Direct Attach Copper (DAC) splitter cable for NDR200-class InfiniBand and 200GbE fabrics. The cable presents one OSFP head at the switch end and breaks out into four QSFP112 connectors at the host end. Each QSFP112 leg runs at NDR200 (200 Gb/s), with the OSFP head aggregating 4 x 200 Gb/s for an 800 Gb/s total. It is an HPE-branded, factory-assembled passive copper assembly — no optics, no retimers, no separable transceivers.
Q. Is the P65330-001 a 1-to-1 cable or a splitter?
It is a 1:4 hybrid splitter — one OSFP connector at the switch end and four QSFP112 connectors at the host end. It is not interchangeable with a 1:1 OSFP-to-OSFP cable or with a 1:2 splitter, and the four legs are not separable transceivers.
Q. Can the QSFP112 legs run at NDR (400 Gb/s) per port?
No. Each QSFP112 leg is rated for NDR200 (200 Gb/s) only. The cable is engineered as a 4 x NDR200 splitter from a single 800G OSFP source; the legs do not support per-port NDR at 400 Gb/s.
Q. What HPE and NVIDIA hardware is the P65330-001 compatible with?
It is built for HPE-supported NDR-class InfiniBand fabrics — typically HPE Cray EX and HPE ProLiant Compute systems using NVIDIA Quantum-2 switches (QM9700 / QM9790) with OSFP ports configured for splitter (1:4) mode, feeding NVIDIA ConnectX-7 NDR200 host adapters in QSFP112 cages. The switch port must be enabled for split mode for the link to come up.
Q. Will this HPE-branded cable work on non-HPE Quantum-2 switches?
The EEPROM on a P65330-001 identifies as HPE. It is intended for HPE-validated configurations; on non-HPE OEM stacks the vendor compatibility list may flag the EEPROM, either accepting the link with a warning or refusing it. Verify against the target switch vendor's HCL before deploying outside an HPE fabric.
Q. Where is a 3 m NDR200 splitter typically deployed?
A 3 m splitter sits in the intra-rack to immediately-adjacent-rack window — fanning one Quantum-2 OSFP switch port out to four ConnectX-7 NDR200 hosts in the same rack or in a neighbouring rack. Typical workloads at this speed class are AI / HPC training fabrics, GPU east-west interconnect, and NVMe-oF storage targets at NDR200.
Q. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each P65330-001 is inspected by T.E.S IT-SOLUTIONS — every connector is examined, DC continuity is measured per lane, and port detection is validated on representative NDR200 hardware before shipment. Cables ship from EU stock in anti-static packaging with global B2B shipping options.
