Bend insensitive fibre paired with high-performance MPO connectors delivers reliable connectivity for dense data centre and carrier-grade applications.
Overview
The NSComm MPO 16F APC to 2xMPO 8F APC breakout cable is a high-density OM4 multimode splitter solution engineered for 400G/800G data center architectures. With one 16-fiber MPO-16 APC (Female) trunk breaking out to two 8-fiber MPO-8 APC (Female) legs, this assembly supports 16-fiber parallel optics in a compact, factory-terminated form factor that simplifies high-speed backbone design. The MPO-16 APC end features an 8-degree angled polish to deflect internal back reflections away from the transceiver, helping preserve signal integrity at very high line rates.
Built with bend-insensitive OM4 50/125 μm multimode fiber and a riser-rated OFNR jacket, this crossover breakout cable is purpose-built for linking two 400G QSFP-DD/OSFP multimode transceivers to a single 800G QSFP-DD optics port in high-speed fiber links. Compared with deploying separate breakout cassettes, MPO-based breakout cables reduce the number of mated interfaces, resulting in lower overall insertion loss, reduced latency, and lower material and installation costs, ideal for hyperscale and large enterprise data centers.

Why Choose NSComm MPO 16F to 2xMPO 8F APC OM4 Breakout Cables?
-
Designed for 400G/800G fanout – Ideal for aggregating two 400G QSFP-DD/OSFP multimode ports into a single 800G QSFP-DD link.
-
Crossover breakout architecture – Pre-engineered crossover polarity simplifies direct device-to-device parallel optics connections.
-
Lower loss than cassette-based solutions – Direct breakout reduces mated interfaces, improving insertion loss and overall link margin.
-
8° APC angled polish – High return-loss APC interface helps minimize back reflections and maintain clean multimode signals.
-
Bend-insensitive OM4 multimode fiber – Ensures stable performance in tight pathways and dense patch field environments.
-
Riser-rated OFNR construction – Suitable for structured cabling, in-rack routing, and data center riser pathways.
Length Options
Standard stocked lengths:
Available in common trunk and breakout lengths suited for typical 400G/800G switch-to-switch and switch-to-transceiver fanout scenarios within and between racks.
Custom lengths:
Custom trunk lengths, breakout leg lengths, labeling, and connector configurations are available on request to match your panel layouts, routing paths, and optics locations.
