Description
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.
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
