ScaleFibre 1:2 MPO Splitter Cables are precision-engineered Y-cables designed for next-generation AI and high-performance computing clusters. They provide the critical optical link between NVIDIA DGX H100, H200, GH200, and Quantum-2 InfiniBand switches.

These assemblies are optically equivalent to the MFP7E20-Nxxx (Multimode OM4) and MFP7E40-Nxxx (Single-mode) series. They connect to a single MPO port on an 800G Twin-Port OSFP transceiver, splitting the 400G signal into two discrete 200G (NDR200) links. This allows a standard 800G switch port to support up to four 200G ConnectX-7 adapters.

These cables feature MPO/APC (Angled Physical Contact) connectors on both Multimode and Single-mode versions to minimise signal reflection. They utilise a specific Type-B crossover pinout to ensure correct lane mapping between the switch and adapter.

Intended for NVIDIA DGX H100, H200, GH200, and Quantum-2 InfiniBand 1:2 breakout across the North American hyperscale AI compute clusters (Ashburn Northern Virginia, Dallas-Fort Worth, Quincy Washington). Splits each 400G port of an 800G OSFP into two NDR200 links for ConnectX-7 adapters in AI training fabrics.
