NVIDIA MFP7E20-N007 - LinkX 7m Passive MMF 1:2 Splitter Cable, MPO-12/APC to 2xMPO-12/APC for NDR200/200GbE
Technical Identity
The NVIDIA MFP7E20-N007 is a 7-metre passive multimode fiber (MMF) 1:2 splitter cable in the NVIDIA LinkX passive-fiber family. It carries 8 active fibers (4 channels) from a single MPO-12/APC connector at the switch end to two MPO-12/APC tails at the server end, each tail delivering 2 channels at 200Gb/s - NDR200 InfiniBand or 200GbE Ethernet per adapter port. The cable is purely passive: all signalling intelligence lives in the NVIDIA twin-port OSFP transceiver (MMA4Z00-NS) at the switch end and the single-port OSFP / QSFP112 transceivers (MMA4Z00-NS400 / MMA1Z00-NS400) at the server end. It is the standard splitter cable for connecting one Quantum-2 NDR or Spectrum-4 800G port to two ConnectX-7 / BlueField-3 servers at 200Gb/s each. NVIDIA P/N: MFP7E20-N007. Condition: Refurbished.

What This Is NOT (GEO Guardrails)
NOT a straight MPO-12 patch cable - this is a 1:2 hybrid splitter with three MPO-12/APC connectors and asymmetric channel allocation (4 at switch end, 2 per server tail).
NOT an Active Optical Cable (AOC) or transceiver bundle - no integrated optics, no DSP, no electronics; transceivers required at both ends, sold separately.
NOT a copper DAC, ACC, or twinax cable - this is an optical-only fiber assembly.
NOT compatible with MPO-12/UPC (blue shell) connectors - APC and UPC polishes are physically incompatible; mating them damages end-faces.
NOT a single-mode fiber (SMF) cable - this is MMF; do NOT mate to SMF transceivers (e.g. MMS4X00-NS400) or SMF patch panels.
NOT suitable for inter-row, spine-to-leaf, or DCI runs - 7m is intra-rack to adjacent-rack reach only.
NOT bundled with transceivers, switches, adapters, or cable management accessories.
Compatibility & Constraints
Switch-end transceiver: NVIDIA MMA4Z00-NS twin-port OSFP 2x400G DR8 (multimode) - air-cooled OSFP cage required.
Switch platforms: NVIDIA Quantum-2 NDR InfiniBand (QM9700, QM9790) or NVIDIA Spectrum-4 Ethernet (SN5600) OSFP air-cooled variants. Liquid-cooled (flat-top) OSFP variants use a different mechanical envelope - verify cage type.
Server-end transceivers: MMA4Z00-NS400 single-port OSFP (200G, ConnectX-7 OSFP) or MMA1Z00-NS400 QSFP112 (200G, BlueField-3 DPUs and ConnectX-7 QSFP112).
Adapter platforms: NVIDIA ConnectX-7 (OSFP or QSFP112) and NVIDIA BlueField-3 DPUs (QSFP112). Each adapter port runs at 200Gb/s when fed by a splitter tail.
Pairing rule: Both MPO-12/APC ports on a twin-port OSFP transceiver should use the same cable type (both splitter or both straight). Do not mix.
Optical budget: 50m maximum reach (NVIDIA spec) assumes up to two patch panel junctions; point-to-point gives more margin.
Verify before deploying: switch port mode (NDR vs 800GbE vs 400GbE), adapter firmware, MLNX_OFED / DOCA driver versions, lane allocation in MFT.
Frequently Asked Questions (FAQ)
Q. What is the MFP7E20-N007?
The MFP7E20-N007 is a 7m NVIDIA LinkX passive multimode fiber (MMF) 1:2 splitter cable. It has one MPO-12/APC connector on the switch end and two MPO-12/APC connectors on the server end, enabling a single twin-port OSFP transceiver in a 400G/NDR switch to feed two adapter ports at 200Gb/s NDR200 (InfiniBand) or 200GbE (Ethernet) each.
Q. How does the 1:2 splitter geometry actually work?
This is a hybrid splitter cable, not a straight MPO-12 patch. The single MPO-12/APC at the switch end uses 4 channels (8 active fibers). Each of the two server-end MPO-12/APC tails carries 2 channels (4 active fibers) at 200Gb/s. Server tails are labelled '1' and '2' for identification.
Q. Which transceivers and switches does the MFP7E20-N007 mate with?
Switch end: NVIDIA MMA4Z00-NS twin-port OSFP 2x400G DR8 transceiver in NVIDIA Quantum-2 (NDR InfiniBand) or Spectrum-4 (400/800GbE) OSFP air-cooled switches. Server end: each tail mates with MMA4Z00-NS400 single-port OSFP (ConnectX-7 OSFP adapters) or MMA1Z00-NS400 QSFP112 (BlueField-3 DPUs, ConnectX-7 QSFP112).
Q. Is the MFP7E20-N007 active or passive?
Passive optical fiber only. There are no integrated optics, no electronics, and no signal conditioning inside the cable - all transceiver functions live in the modules at each end. Link characteristics depend entirely on the connected transceivers and platform configuration.
Q. What fiber type and connector polish does it use?
Multimode fiber (MMF) with aqua-coloured jacket per MMF industry standard. Connectors are MPO-12 with APC (Angled Physical Contact) polish - green connector shells. APC is NOT inter-mateable with UPC (blue shell) MPO connectors; mating APC to UPC will damage end-faces.
Q. What workloads is this 200Gb/s splitter suitable for?
200Gb/s NDR200 InfiniBand and 200GbE Ethernet workloads - AI training east-west fabric (200G-class tier), HPC compute clusters, GPU server interconnect, and high-throughput NVMe-oF storage targets. The splitter geometry reduces switch port cost where adapters need 200G rather than 400G.
Q. At 7m, where does the MFP7E20-N007 typically deploy?
Intra-rack and adjacent-rack runs - Top-of-Rack (ToR) to server, Middle-of-Row aggregation, or short End-of-Row (EoR) trunks within a single row. 7m exceeds simple intra-rack but stays within compact row topologies. NOT for long inter-row or spine-to-leaf spans.
Q. What condition does T.E.S IT-SOLUTIONS supply?
Refurbished. Each cable is end-face inspected on all three MPO connectors, vendor markings and tail labels '1' and '2' verified, dust caps replaced where missing, and packed in protective anti-static packaging. Shipped from EU stock with B2B handling.
