NVIDIA Mellanox MFP7E40-N030 400G NDR Passive Splitter Fiber Cable, 1×MPO12 APC to 2×MPO12 APC, SMF 30m: This is a 30-meter passive single-mode fiber (SMF) splitter cable with one MPO12 APC connector on the host side breaking out to two MPO12 APC connectors at the destination side, intended for OSFP NDR-class optical interconnects. This is a passive fiber assembly — there are no transceivers, electronics, or active optics in the cable; it is meant to be paired with separate OSFP transceivers on each end. This is a new, unused unit.
Engineering Context
The MFP7E40-N030 functions as the structured-cabling element of an OSFP NDR2 splitter topology, where a single 800Gb/s OSFP port is broken into two 400Gb/s NDR links over independent MPO12 APC trunks. APC (Angled Physical Contact) end-faces are required to control back-reflection on long-distance SMF runs at 1310nm. Because the cable is passive, signal integrity depends on the matched OSFP transceivers and on clean MPO end-faces. At 30 meters it is well within the SMF parallel-fiber reach budget of the NDR optical modules it is designed for.
Deployment & Use Cases
Splitting a 2×400G NDR2 OSFP switch port into two independent 400G NDR endpoints. Aggregation-layer to leaf-switch trunking in NVIDIA Quantum-2 InfiniBand fabrics. GPU compute pod uplinks where one port on a Quantum-2 QM9700 switch needs to feed two ConnectX-7 NDR adapters in different racks. Structured cabling in 400GbE NDR-class Ethernet fabrics where SMF is the building cable plant standard.
Technical Specifications
OEM: NVIDIA Mellanox
Part Number: MFP7E40-N030
Cable Type: Passive Splitter Fiber Cable (no electronics)
Connectors: 1× MPO12 APC to 2× MPO12 APC
Fiber Type: Single-Mode Fiber (SMF)
End-Face: APC (Angled Physical Contact)
Length: 30m
Application Class: 400G NDR per leg (used in 2×400G OSFP NDR2 splitter topologies)
Protocol Support: InfiniBand NDR and 400GbE Ethernet, when paired with the matching OSFP transceivers
Condition: New — Tested and certified by T.E.S IT-SOLUTIONS
Compatibility & Constraints
Compatible with NVIDIA OSFP NDR transceivers that use parallel-SMF MPO12 APC interfaces (for example DR4/FR4-class OSFP modules) and with NVIDIA Quantum-2 NDR switches and ConnectX-7 NDR adapters. The two split legs operate as independent 400G links and are not bonded by the cable itself. Not a transceiver and not an Active Optical Cable — a separately purchased OSFP optic is required at every end. Not compatible with multi-mode-only OSFP modules (SR-class) or with UPC end-face MPO equipment. Not a breakout from QSFP-DD; this is OSFP-class cabling.
