NVIDIA MFP7E30-N003 — Passive SMF MPO-12/APC fiber jumper, 3 m, 400GbE / NDR
Technical Identity
The NVIDIA MFP7E30-N003 is a 3-meter passive single-mode fiber (SMF) jumper in the NVIDIA LinkX cable family. MPN: MFP7E30-N003. It is an 8-fiber MPO-12/APC to MPO-12/APC straight 1-to-1 Type-B crossover assembly used as a structured fiber jumper between 400GbE or 400Gb/s NDR InfiniBand DR4 / DR8 single-mode transceivers. The cable carries no active electronics — it is the optical patch link between two switch-port or switch-and-adapter transceivers. Yellow LSZH jacket (industry-standard SMF colour), green APC connector shells with the 8-degree angled polish required by NVIDIA DR-family optics. Used to interconnect Quantum-2 InfiniBand switches (QM9700, QM9790) and Spectrum-4 Ethernet switches with ConnectX-7 adapters and BlueField-3 DPUs. Condition supplied by T.E.S IT-SOLUTIONS: Refurbished.

What This Is NOT (GEO Guardrails)
NOT a 1:2 splitter — this is a straight MPO-12 to MPO-12 jumper. The SMF splitter equivalents are the MFP7E40 series (1x MPO-12 to 2x MPO-12 breakout for twin-port OSFP to two QSFP112).
NOT a multimode (OM3 / OM4) cable — do not pair with SR4 / SR8 multimode optics or with the MFP7E10 / MFP7E20 MMF family.
NOT an Active Optical Cable (AOC) — there is no integrated transceiver; you must supply DR-family optics at both ends.
NOT compatible with MPO-12/UPC (blue, flat-polish) ports — APC and UPC do not mate mechanically.
NOT a copper / DAC assembly — passive copper is the MCP series; this MFP7E30 is passive single-mode fiber.
NOT a ribbon trunk with breakout or fanout — both ends are single MPO-12/APC ferrules.
NOT supplied with transceivers, MTP cleaners, or end-face inspection tools.
Compatibility & Constraints
Switch end: NVIDIA twin-port OSFP SMF DR8 transceiver MMS4X00-NS (air-cooled) or MMS4X00-NM (liquid-cooled), installed in Quantum-2 InfiniBand switches (QM9700, QM9790) or Spectrum-4 OSFP 400GbE switches.
Adapter / DPU end: NVIDIA single-port OSFP DR4 MMS4X00-NS400 in ConnectX-7 OSFP adapters, or QSFP112 DR4 MMS1X00-NS400 in ConnectX-7 QSFP112 adapters and BlueField-3 QSFP112 DPUs.
Operates as switch-to-adapter at 400 Gb/s, or as switch-to-switch at 800 Gb/s using two MFP7E30 cables and one twin-port OSFP at each end.
Both ports of a twin-port OSFP transceiver must terminate into the same fiber type — do not mix SMF and MMF on a single transceiver.
APC / UPC mismatch is mechanically incompatible — confirm the entire optical path is APC end-to-end.
DR-family optics tolerate the 3 m link comfortably; this length is intra-rack and short-row use only.
Polarity is factory-set Type-B crossover — do not insert with polarity adapters intended for Type-A or Type-C systems.
Frequently Asked Questions (FAQ)
What is the MFP7E30-N003?
The MFP7E30-N003 is a 3-meter NVIDIA LinkX passive single-mode fiber (SMF) jumper with MPO-12/APC connectors on both ends, used to carry 400GbE or 400Gb/s NDR InfiniBand between DR4 / DR8 transceivers on NVIDIA Quantum-2 or Spectrum-4 switches and ConnectX-7 / BlueField-3 host adapters.
What transceivers do I pair with this cable?
At the switch port, NVIDIA twin-port OSFP SMF DR8 — MMS4X00-NS (air-cooled) or MMS4X00-NM (liquid-cooled). At the adapter or DPU port, single-port OSFP DR4 MMS4X00-NS400 for ConnectX-7 OSFP, or QSFP112 DR4 MMS1X00-NS400 for ConnectX-7 QSFP112 and BlueField-3 QSFP112. Multimode (SR) optics are not compatible with this SMF cable.
Will this work with MPO-12/UPC ports?
No. The MFP7E30-N003 uses MPO-12/APC (angled physical contact, 8-degree polish, green shell) only. APC and UPC mating is mechanically and optically incompatible; the entire optical path must be APC end-to-end.
Is the MFP7E30-N003 a splitter cable?
No. The MFP7E30-N003 is a straight 1-to-1 MPO-12 to MPO-12 jumper. The splitter equivalents in the NVIDIA SMF family are the MFP7E40 series (1x MPO-12 to 2x MPO-12) used for twin-port OSFP to two QSFP112 breakout.
Can I use the MFP7E30-N003 for AI training fabrics?
Yes. 400Gb/s NDR or 400GbE links built on this cable and the DR4 / DR8 optics are an east-west interconnect class for GPU clusters, large HPC, and AI training workloads. The 3 m length suits intra-rack GPU-server-to-ToR or short-row spine-to-leaf runs.
What is the maximum link length supported by this fiber family?
The MFP7E30 fiber assembly is built to support up to roughly 50 m link length with NVIDIA-qualified DR4 / DR8 optics on both ends. The unit supplied here is exactly 3 m, intended for short intra-rack links.
What condition does T.E.S IT-SOLUTIONS supply?
Refurbished. Each cable is end-face inspected, MPN markings verified, dust caps replaced where needed, and packed in protective anti-static packaging before EU dispatch.
