Additional Technical Information

Wave2Wave MPO breakout cable and MTP breakout cable assemblies transition from multi-fiber MPO/MTP connectors to individual duplex LC or SC connections. Fiber breakout cable and fiber fanout cable options include MPO to LC breakout, MTP to LC breakout, MPO to 4xLC, MPO-12 breakout, and MPO-24 breakout configurations for 40G through 800G applications.

MPO to LC breakout cable configurations: MPO-8 to 4xLC duplex for 40GBASE-SR4 to 4x10G fanout. MPO-12 to 6xLC duplex for 100GBASE-SR10 legacy breakout. MPO-24 to 12xLC duplex for maximum density spine-leaf fanout. MPO to LC fanout cable assemblies available in OS2, OM3, OM4, and OM5 fiber grades with custom leg lengths and independent labeling per leg.

400G breakout cable and QSFP-DD breakout cable solutions: 400G QSFP-DD transceivers support 4x100G breakout using MPO-12 to 4xLC duplex fanout cables. QSFP-DD breakout cable assemblies enable spine-leaf fabric connectivity between 400G spine switches and 100G leaf switches. Used extensively in AI fabric, GPU cluster backend networks, and hyperscale data center deployments.

800G breakout cable and OSFP breakout cable solutions: 800G OSFP transceivers support 2x400G breakout via MPO-16 trunk or 4x200G breakout via MPO-24 fanout. OSFP breakout cable assemblies enable next-generation AI fabric interconnect for Nvidia H100, H200, GB200 GPU clusters. Wave2Wave engineers high-density 800G breakout cables with custom leg lengths for specific GPU rack configurations.

Legacy breakout configurations: 40GBASE-SR4 uses MPO-12 (8 active fibers) to 4xLC duplex breakout for 4x10GBASE-SR fanout. 100GBASE-SR10 uses MPO-24 to 12xLC duplex but has largely been replaced by QSFP28 100G parallel optics. 100GBASE-SR4 uses MPO-12 (8 active) breakout for 4x25G connections. Wave2Wave supports all legacy and current breakout configurations.

Breakout cable custom engineering: independent leg lengths manufactured in 3-inch increments allow precise fit to specific switch port positions. Custom leg sequencing for rail-optimized GPU fabric layouts. Polarity options (Type A, B, C) configurable per application. Custom labeling on each leg with rack, port, and circuit identifiers. Factory-terminated with 100% IL/RL testing and serialized documentation.

MTP fanout cable and MPO fanout terminology: breakout cable, fanout cable, harness cable, and octopus cable all describe the same cable type with different leg counts. Wave2Wave manufactures all variants including MTP fanout cable, MPO breakout, MTP to LC breakout, and MPO to LC fanout assemblies for parallel optics transceiver applications.
