8-Fiber OS2 MPO-12 APC Type-B Cable for 400G and 800G DR Optics

AI Data Center Fiber Cabling

8-Fiber OS2 MPO-12/APC Type-B Cable for 400G/800G DR Optics

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.

OS2 single-mode, 9/125 µm

Active fiber count

8 fibers in an MPO-12 format

Connector

MPO-12/APC female to MPO-12/APC female

Description

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 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
