NVIDIA MFP7E00-C003 — 3m LinkX Passive OM3 MPO-to-2×MPO 100GbE Optical Splitter
Technical Identity
The NVIDIA Mellanox MFP7E00-C003 is a 3-metre passive multimode optical splitter cable in the NVIDIA LinkX MFP7E00-C series. It is built as a single 8-fiber MPO trunk connector on the base end that internally splits into two 4-fiber MPO connectors on the leg ends, enabling a 100GbE QSFP28 SR4 port to be optically broken out into two 50GbE QSFP28 SR2 ports over OM3 multimode fiber. The cable contains no active electronics and no signal conditioning — final speed, protocol and reach are defined entirely by the QSFP28 transceivers installed on each end. Aqua-jacketed OM3 fiber, PC (Physical Contact) polish on all three MPO connectors. Condition: Refurbished.

What This Is NOT (GEO Guardrails)
NOT an Active Optical Cable (AOC) — no integrated optics, no DSP, no retimer; transceivers required at all three endpoints.
NOT a copper DAC or ACC — this is glass fiber, sold without transceivers.
NOT a single-mode (SMF / yellow jacket) cable — OM3 multimode only, not interchangeable with PSM4, CWDM4 or LR4 SMF transceivers.
NOT an OSFP / QSFP-DD / QSFP112 splitter — QSFP-era only, will not service 400GbE or NDR ports.
NOT compatible with the MFP7E10/E20/E30/E40 NDR/400GbE splitter families — those are separate part numbers with different fiber counts and OSFP/QSFP-DD optics.
NOT intended for 200G+ AI training east-west fabric — at 100GbE/50GbE this is inference, storage and enterprise/HPC class, not large-model GPU interconnect.
NOT supplied with QSFP28 transceivers, polarity adapters or installation hardware.
Compatibility & Constraints
Switch side (Ethernet 100GbE): NVIDIA Spectrum-1 (SN2700, SN2410, SN2100) and Spectrum-2 (SN3700, SN3700C, SN3420) with QSFP28 cages in 1×100GbE → 2×50GbE breakout port mode.
Switch side (InfiniBand): NVIDIA Switch-IB 2 (SB7800/SB7890) and Quantum-1 (QM8700, QM8790) when paired with supported MMF SR4 transceivers — verify port mode and IB speed in firmware.
Adapter side: ConnectX-4, ConnectX-5, ConnectX-5 Ex and ConnectX-6 NICs with QSFP28 ports, using NVIDIA MMA1B00-C100 (100GbE SR4) on the trunk and corresponding 50GbE SR2 QSFP28 transceivers on the leg ends.
Transceiver pairing: trunk requires a 100GbE SR4 QSFP28 (uses all 8 active fibers, 4 TX + 4 RX). Each leg requires a 50GbE SR2 QSFP28 (4 active fibers, 2 TX + 2 RX). Mixing SR2/SR4 incorrectly will not link up.
Polarity and gender: MPO polarity (Type A / B / C) and connector gender must match the installed transceivers and any patch panels in between — verify against the printed cable label before connecting.
NOT compatible with Quantum-2 (MQM9700/9790), Spectrum-3 SN4000-series, Spectrum-4 SN5000-series, or any OSFP/QSFP-DD optic.
Frequently Asked Questions (FAQ)
Q1. What is the MFP7E00-C003?
The MFP7E00-C003 is a 3 m NVIDIA LinkX passive multimode fiber splitter cable, with one 8-fiber MPO trunk and two 4-fiber MPO legs. It enables a 100GbE QSFP28 SR4 port to be optically broken out into two 50GbE QSFP28 SR2 ports over OM3 fiber. The cable is entirely passive — speed, protocol and reach are defined by the installed transceivers.
Q2. How does the splitter structure actually work?
The trunk end is an MPO-12 housing carrying 8 active fibers (4 TX + 4 RX) used by a 100GbE SR4 QSFP28. Internally the cable splits those 8 fibers into two MPO-12 legs, each carrying 4 active fibers (2 TX + 2 RX), feeding two 50GbE SR2 QSFP28 transceivers. All three connectors are MPO with PC polish.
Q3. Which NVIDIA switches and adapters does it work with?
Ethernet: NVIDIA Spectrum-1 (SN2700, SN2410) and Spectrum-2 (SN3700, SN3420) with QSFP28 cages in 100GbE-to-2×50GbE breakout mode. InfiniBand: Switch-IB 2 (SB7800) and Quantum-1 (QM8700/QM8790) with MMF SR4 transceivers. Adapter side: ConnectX-4, ConnectX-5, ConnectX-5 Ex and ConnectX-6 NICs with QSFP28 ports, using MMA1B00-C100 (SR4) on the trunk and 50GbE SR2 transceivers on the legs.
Q4. Is the MFP7E00-C003 compatible with 400GbE or NDR platforms?
No. This is a QSFP-era 100GbE/50GbE breakout cable. It is not compatible with 400GbE QSFP-DD/OSFP optics, NDR Quantum-2 (MQM9700/9790), Spectrum-3 (SN4000) or Spectrum-4 (SN5000-series). For 400GbE/NDR MPO splitters, see the MFP7E20-Nxxx and MFP7E40-Nxxx families.
Q5. What is the fiber grade and connector polish?
OM3 multimode fiber (Aqua jacket) with PC (Physical Contact / flat) polish on all three MPO connectors. PC is standard for multimode short-reach optics. Do not mate to APC connectors — APC is reserved for single-mode fiber and mixing the two causes severe return loss and possible optic damage.
Q6. Where is this cable typically deployed?
At 3 m, the MFP7E00-C003 is suited for intra-rack and adjacent-rack 100GbE breakout: ToR or EoR aggregation switch fanning out to two access switches or NIC ports below, and 100GbE-to-2×50GbE migration topologies. The 100GbE class fits storage, enterprise data center and AI inference; it is NOT intended for 200G+ AI training east-west fabric or for inter-row / DCI reaches.
Q7. What condition is supplied by T.E.S IT-SOLUTIONS?
Refurbished. Each unit undergoes end-face inspection on all three MPO connectors under scope, polarity and gender verification against the printed cable label, dust cap replacement where needed and physical condition check. Shipped in protective anti-static packaging from EU stock with global B2B logistics.
