NVIDIA MFP7E10-N020 Passive MMF Fiber Cable MPO-12 APC to MPO-12 APC 20m
Technical Identity
The NVIDIA Mellanox MFP7E10-N020 is a 20-meter passive multimode optical fiber cable in the NVIDIA LinkX family, engineered for 400GbE Ethernet and NDR (400 Gb/s) InfiniBand data-center fabrics. It is a straight, eight-fiber MPO-12/APC to MPO-12/APC multimode assembly used to interconnect Quantum-2 NDR InfiniBand switches and Spectrum-4 400GbE Ethernet switches with ConnectX-7 network adapters or BlueField-3 DPUs through paired optical transceivers. The cable contains no active electronics — all link speed, protocol, FEC, and reach behavior is determined entirely by the transceivers installed at each end and by the host platform configuration. Condition: Refurbished.

What This Is NOT

NOT a 1-to-2 splitter or breakout cable — this is a straight MPO-12 to MPO-12 trunk
NOT an Active Optical Cable (AOC) and NOT a copper DAC or ACC — no integrated transceivers or signal conditioning
NOT compatible with MPO-12/UPC connectors (blue shell, flat polish) — APC and UPC polishes are physically and optically incompatible
NOT a single-mode fiber assembly — do not pair with single-mode (yellow-jacket) transceivers
NOT supplied with optical transceivers, adapters, brackets, or installation accessories
NOT a host-bus adapter and NOT a switch — it is purely a passive fiber interconnect

Compatibility

Switch end: NVIDIA Twin-port OSFP transceivers (MMA4Z00-NS, 2× 400 Gb/s) in Quantum-2 NDR InfiniBand switches (MQM9700/MQM9790 series) or Spectrum-4 400GbE Ethernet switches
Adapter / DPU end: single-port OSFP MMA4Z00-NS400 for ConnectX-7 OSFP cards, or QSFP112 MMA1Z00-NS400 for ConnectX-7 QSFP112 cards and BlueField-3 DPUs
Lane mapping: Each MPO-12 trunk carries one 400 Gb/s link (8 lanes × 50 Gb/s PAM4). Twin-port OSFP transceivers must use the same fiber polarity and type on both MPO-12 ports
Polish: APC-to-APC only — do not mate with UPC connectors
Topology: 20 meters supports inter-rack and row-level interconnect within an AI/HPC fabric pod; verify reach budget against the transceiver datasheet when patch panels are present
Pre-deployment: Verify firmware, driver, port-mode (Ethernet vs. InfiniBand), breakout configuration, and FEC settings on the host platform before installation

Frequently Asked Questions
What is the MFP7E10-N020 used for?
The MFP7E10-N020 is a 20m NVIDIA LinkX passive MMF fiber cable. It is a straight MPO-12/APC to MPO-12/APC trunk used to interconnect 400GbE / NDR InfiniBand switches (Spectrum-4, Quantum-2) and ConnectX-7 adapters or BlueField-3 DPUs in AI, HPC, and high-throughput data-center networks.
Is the MFP7E10-N020 passive or active?
Passive multimode fiber only. It has no integrated optics, no signal-conditioning electronics, and no transceiver modules. All protocol, speed, and reach behavior depends on the optical transceivers installed at each end.
What fiber type and connectors does it use?
OM4 multimode fiber with MPO-12/APC connectors at both ends (8-degree angle polish, green shell). Eight fibers are used (4 Tx + 4 Rx) in a Type-B straight crossover. Aqua LSZH jacket for fire-safety compliance.
Which transceivers does this cable work with?
Switch end: NVIDIA Twin-port OSFP DR8 (MMA4Z00-NS). Adapter or DPU end: single-port OSFP (MMA4Z00-NS400) for ConnectX-7/OSFP, or QSFP112 (MMA1Z00-NS400) for ConnectX-7 and BlueField-3 DPUs. Verify port mode and lane mapping against your platform before deployment.
Can the MFP7E10-N020 be used with MPO-12/UPC connectors?
No. MPO-12/APC (green shell, 8-degree angle polish) and MPO-12/UPC (blue shell, flat polish) are physically and optically incompatible. Do not attempt to mate them — use APC-to-APC only.
What condition does T.E.S IT-SOLUTIONS supply?
Refurbished. Each cable is end-face inspected, connector and vendor markings verified against MPN, dust caps replaced as needed, and shipped from EU stock in protective anti-static packaging for B2B delivery.
Why Choose T.E.S IT-SOLUTIONS
T.E.S IT-SOLUTIONS is a Europe-based NVIDIA Mellanox specialist serving HPC, AI, and enterprise data-center procurement teams since 2007. Every MFP7E10-N020 cable is identified by MPN and vendor marking, end-face inspected, fitted with replacement dust caps where required, and packed in protective anti-static cable packaging for global B2B shipment. Buyers receive multi-currency invoicing, EU stock with worldwide express logistics, and direct pre-sale engineering consultation on Quantum-2 / Spectrum-4 transceiver pairing, reach budgets, and 400GbE / NDR fabric topology — not a call-center.
