NVIDIA Mellanox MFP7E40-N010 Passive Splitter Fiber Cable, MPO12 APC to 2×MPO12 APC, 400Gb/s NDR, SMF, 10m: This is a 10-meter passive single-mode fiber (SMF) splitter cable engineered for 400Gb/s NDR InfiniBand and Ethernet point-to-multipoint interconnect. The MFP7E40-N010 (NVIDIA P/N 980-9I58N-00N010) is a passive optical fiber assembly that requires pluggable transceivers on both ends — it is not an active optical cable (AOC) and does not contain integrated optics. This is a new (factory-sealed) unit.
Engineering Context
The MFP7E40-N010 splits a single MPO12 APC port on the switch side into two MPO12 APC ports on the host side, enabling a 1:2 port breakout topology when paired with single-port OSFP DR8 transceivers. Single-mode fiber construction supports the longer reach budget required for SMF DR optics. The APC (Angled Physical Contact) end-faces reduce return loss versus UPC, which is mandatory for high-bit-rate single-mode optical links. The cable is fixed at 10m and is not field-terminable.
Deployment & Use Cases
Connecting a single 400Gb/s NDR switch port to two 200Gb/s NDR200 host adapters in spine-leaf or rail-optimized topologies. Breakout cabling for ConnectX-7 and BlueField-3 hosts paired with Quantum-2 NDR switches. AI training cluster fabrics where 1:2 splitting reduces switch port count. Cross-rack runs in HPC and hyperscale deployments where SMF reach is required.

Protocol: InfiniBand NDR / 400GbE Ethernet
Connector End-Face: APC (Angled Physical Contact)
Condition: New — factory-sealed, tested by T.E.S IT-SOLUTIONS
Compatibility & Constraints
Requires pluggable single-mode transceivers on both ends — for example, NVIDIA MMA4Z00-NS twin-port OSFP DR8 transceivers on the switch side and OSFP DR4 / QSFP112 DR4 transceivers on the host side. Compatible with NVIDIA Quantum-2 (QM9700, QM9790) and Spectrum-4 (SN5000 series) switches when configured for 1:2 splitter mode. Not compatible with multi-mode (MMF) transceivers — using SR optics on this SMF cable will not link. Not compatible with copper DAC or AOC ports; pluggable optical transceivers are mandatory. Not field-terminable; fixed 10m length.
