NVIDIA MFP7E20-N020 Passive MMF Splitter Cable MPO12 APC to 2×MPO12 APC NDR200 20m
Technical Identity
The NVIDIA Mellanox MFP7E20-N020 is a 20m passive multimode optical fiber 1:2 splitter cable in the NVIDIA LinkX family. It connects one port of an NVIDIA Twin-port OSFP 800Gb/s transceiver in a Quantum-2 NDR InfiniBand or Spectrum-4 400GbE Ethernet switch to two ConnectX-7 adapters or BlueField-3 DPUs, delivering 200Gb/s per server (NDR200 InfiniBand or 200GbE Ethernet). The trunk uses a 4-channel MPO-12/APC connector at the switch end; the two server-end tails each carry 2 channels through MPO-12/APC connectors. The cable contains no active electronics — it is passive fiber only. Condition: Refurbished.
Specifications

Brand: NVIDIA Mellanox
Model / MPN: MFP7E20-N020
Product type: Passive optical fiber cable — 1:2 splitter
Product family: NVIDIA LinkX Passive Fiber (MPO-12 APC splitter series)
Structure: 1× MPO-12/APC (4-channel trunk, switch end) → 2× MPO-12/APC (2-channel each, server end)
Active fibers: 8 total (4 channels of TX+RX) — 4 fibers per server tail
Connector: MPO-12/APC, angle-polished, green connector shell; server tails labeled '1' and '2'
Fiber type: OM4 Multimode Fiber (MMF); aqua jacket (industry standard for MMF)
Jacket: Low-Smoke Zero-Halogen (LSZH)
Length: 20m (measured to the farthest tail end)
Switch-end speed: 400Gb/s NDR (one port of an 800G Twin-port OSFP transceiver)
Server-end speed: 200Gb/s per tail — NDR200 InfiniBand or 200GbE Ethernet
Medium: Passive optical fiber — no active electronics, no signal conditioning
Polarity / polish: APC (Angled Physical Contact); NOT cross-compatible with UPC connectors
Condition: Refurbished

What This Is NOT

NOT a straight 1:1 MPO-12 cable — this is a 1:2 passive splitter with three connectors
NOT an Active Optical Cable (AOC) — contains no integrated optics or signal conditioning electronics
NOT a copper DAC or ACC — optical fiber medium only
NOT compatible with MPO-12/UPC (blue shell) connectors — APC and UPC polishes are physically incompatible
NOT compatible with Single Mode Fiber transceivers — MMF/OM4 only, optimized for 850nm VCSEL optics
NOT supplied with optical transceivers, panels, or installation accessories
NOT for use with a Twin-port OSFP transceiver port that already terminates in a straight MPO-12 cable on its paired port

Compatibility and Hard Constraints

Switch end: requires the NVIDIA Twin-port OSFP 800G MMF transceiver (MMA4Z00-NS) installed in a Quantum-2 InfiniBand or Spectrum-4 Ethernet OSFP air-cooled switch
Server end: each 2-channel tail mates to an OSFP MMF transceiver (MMA4Z00-NS400) or QSFP112 MMF transceiver (MMA1Z00-NS400) on a ConnectX-7 NIC or BlueField-3 DPU, delivering 200Gb/s NDR200 or 200GbE
Both MPO-12/APC ports of a single Twin-port OSFP transceiver must use the same fiber type (both MMF in this configuration)
Maximum reach (specified for 50m parts) assumes up to two optical patch panels with a total of 4 connector junctions; 20m direct attachment leaves margin
Adapter port mode must be configured for 2×NDR200 / 2×200GbE breakout — verify firmware, driver, and switch/adapter port lane assignment before deployment
Do not use with MPO-12/UPC (blue shell) connectors — the APC polish angle prevents proper mating and causes high return loss
Operating environment: indoor data center; observe LSZH cable bend radius and pull-tension limits during installation

Frequently Asked Questions
What is the MFP7E20-N020 used for?
The MFP7E20-N020 is a 20m NVIDIA LinkX passive MMF 1:2 splitter fiber cable. It enables two servers — each receiving 200Gb/s NDR200 InfiniBand or 200GbE Ethernet — to share a single port of an 800G Twin-port OSFP transceiver in a Quantum-2 or Spectrum-4 switch, reducing switch port cost per server in AI, HPC, and high-density data center deployments.
What speed does each server tail deliver?
Each of the two server-end tails delivers 200Gb/s — either NDR200 InfiniBand or 200GbE Ethernet — using 2 of the 4 trunk channels at the switch end. ConnectX-7 and BlueField-3 transceivers automatically reduce power consumption when only 2 channels are active.
What transceivers are compatible with this cable?
Switch end: NVIDIA Twin-port OSFP 800G MMF DR8 transceiver (MMA4Z00-NS). Server end (each tail): OSFP MMF transceiver (MMA4Z00-NS400) for ConnectX-7 OSFP adapters, or QSFP112 MMF transceiver (MMA1Z00-NS400) for ConnectX-7 QSFP112 or BlueField-3 DPUs.
Is this cable active or passive?
Passive optical fiber only. There are no signal-conditioning electronics, retimers, or transceiver modules inside the cable. All protocol selection, speed negotiation, and FEC behavior are determined by the connected transceivers and host platform configuration.
What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each cable is end-face inspected on all three MPO-12/APC connectors, vendor markings and tail labels verified, dust caps replaced where needed, and packed individually in protective anti-static packaging before shipment from EU stock.
