Fibtele technical configuration brief
Product: 8-Fiber OM4 MPO-12/APC Type-B Cable for AI Clusters
Catalog slug: 8-fiber-om4-mpo12-apc-type-b-cable
Category: ai-data-center-fiber-cabling

Published technical record
This low-loss OM4 multimode assembly uses eight active fibers within an MPO-12/APC interface for short-reach parallel-optics links in AI and HPC data centers. It is intended for supported 400G four-lane links and twin-port 2 × 400G optical architectures. Final reach and data rate depend on the transceivers, channel loss budget, connector count, polarity, and installation conditions.

Features
- Eight active 50/125 µm OM4 multimode fibers within an MPO-12 connector format.
- MPO-12/APC female-to-female configuration for supported parallel-optics transceiver interfaces.
- Type-B crossover polarity aligns transmit and receive lanes in direct equipment-to-equipment links.
- Flexible round cable construction for dense rack pathways and cable trays.
- LSZH and other indoor jacket options are available subject to order configuration.
- Custom lengths, labels, polarity documentation, and test reports can be reviewed before ordering.
- The cable must be matched to the exact transceiver MDI; it is not interchangeable with MPO-12/UPC interfaces.

Applications
- Short-reach GPU and DPU fabric links
- AI cluster switch-to-server connections
- 400G four-lane multimode parallel optics
- Twin-port 2 × 400G optical cabling architectures
- High-performance computing and storage fabrics
