Fibtele technical configuration brief
Product: 8-Fiber OS2 MPO-12/APC Type-B Cable for 400G/800G DR Optics
Catalog slug: 8-fiber-os2-mpo12-apc-type-b-cable
Category: ai-data-center-fiber-cabling

Published technical record
This 8-fiber OS2 single-mode cable assembly is designed for supported DR-class parallel-optics links between AI data center switches, adapters, DPUs, and inter-rack infrastructure. The MPO-12/APC Type-B format carries four transmit and four receive fibers. Link reach is determined by the selected optical modules and the complete channel loss budget, not by the passive cable alone.

Features
- Eight active 9/125 µm OS2 single-mode fibers within an MPO-12 connector format.
- MPO-12/APC female connectors support compatible DR parallel-optics interfaces.
- Type-B crossover polarity supports direct transceiver-to-transceiver lane alignment.
- Yellow cable identification follows common single-mode data center practice.
- Suitable for longer rack-to-rack and row-to-row paths than typical multimode links when paired with the correct optics.
- Custom lengths, jacket ratings, labels, and factory test documentation are available by configuration.
- APC and UPC MPO interfaces must not be mixed; confirm the optical module MDI before ordering.

Applications
- AI data center leaf-spine and inter-rack links
- 400G DR4-class parallel optics
- Twin-port 2 × 400G single-mode architectures
- GPU, DPU, storage, and high-performance computing fabrics
- Structured cabling paths using compatible MPO/APC panels
