8-Fiber OM4 MPO-12/APC Type-B Cable for AI Clusters

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.

Product information is for selection and configuration reference. Confirm the final datasheet, test or compliance documents, warranty, and acceptance criteria before ordering.

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
