Bend insensitive fibre paired with high-performance MPO connectors delivers reliable connectivity for dense data centre and carrier-grade applications.
Overview
The NS MPO 12F UPC to 4xLC UPC Duplex harness cable is a high-density OM4 multimode breakout solution designed for migration between duplex and parallel optics in modern data centers. With one 12-fiber MPO UPC (Female) trunk breaking out to four LC UPC duplex connectors, this harness provides 8 active fibers to serve switch, server, or patch panel LC ports while leveraging a compact MPO backbone for cable consolidation.
Factory-terminated and fully tested, the MPO-LC harness delivers verified low insertion loss and stable return loss for improved network integrity in 10G/25G and 40G/100G Ethernet environments. Built with bend-insensitive OM4 50/125 μm multimode fiber and a riser-rated OFNR jacket, it is ideal for high-density cabling in data centers, equipment rooms, and telecommunication rooms where space savings, airflow, and clean cable management are critical. The crossover polarity design simplifies connectivity between MPO backbones and LC front-panel ports in duplex and parallel optics migration scenarios.

Why Choose NS MPO 12F UPC to 4xLC UPC Duplex OM4 Harness Cables?
-
Duplex–parallel migration ready – Bridges MPO-based backbones with LC-based switch and server ports for 10/25G to 40/100G upgrades.
-
High-density breakout design – One MPO trunk to four LC duplex legs reduces front-of-rack congestion and cable bulk.
-
Low-loss, factory-terminated solution – MPO and LC connectors are pre-terminated and tested to maintain tight optical budgets.
-
OM4 bend-insensitive multimode fiber – Supports higher bandwidth and stable performance in tight routing paths.
-
Crossover polarity for clean channel mapping – Pre-engineered polarity simplifies design and reduces patching errors.
-
Riser-rated OFNR construction – Suitable for structured cabling, in-cabinet routing, and high-density data center environments.
Length Options
Standard stocked lengths:
Available in common harness lengths optimized for top-of-rack, middle-of-row, and end-of-row deployments, with balanced trunk and breakout leg lengths for typical switch and patch panel layouts.
Custom lengths:
Custom trunk lengths, breakout leg lengths, labeling, and connector configurations are available on request to match your exact rack layout and cabling design.
