Fibtele technical configuration brief
Product: OM4 MPO-12/APC 1-to-2 Breakout Cable
Catalog slug: om4-mpo12-apc-1-to-2-breakout-cable
Category: ai-data-center-fiber-cabling

Published technical record
This OM4 multimode breakout assembly converts one four-channel MPO-12/APC parallel-optics path into two two-channel MPO-12/APC branches for supported OSFP and QSFP112 topologies. In a compatible twin-port design, two breakout assemblies can provide four independent two-channel branches. Confirm the required lane map, polarity, transceiver operating mode, and loss budget before ordering.

Features
- One four-channel MPO-12/APC side branches into two two-channel MPO-12/APC ends.
- Eight active OM4 multimode fibers are distributed across the two branch legs.
- Type-B crossover construction supports compatible direct optical lane mappings.
- Compact fanout section separates the two branches while protecting the fibers.
- Branch identification and staggered or equal leg lengths can be configured for rack installation.
- Designed for supported parallel-optics breakout architectures; it does not electrically convert data rates.
- Final link operation depends on the transceiver breakout mode and switch or adapter configuration.

Applications
- 400G-to-2 × 200G parallel-optics breakout links
- Twin-port optical fanout designs using two cable assemblies
- GPU and DPU cluster switch-to-adapter connections
- High-density AI and HPC rack cabling
- Storage and accelerated-computing fabrics
