NSComm MPO 12F APC to 4xLC UPC Duplex Harness Cables, 8 Fibers, Singlemode (OS2, G.657.A1), OFNR, Crossover
Overview
The NSComm MPO 12F APC to 4xLC UPC Duplex harness cable is a high-density single mode breakout solution designed for migration between parallel and duplex optics in modern data centers. With one 12-fiber MPO APC (Female) trunk breaking out to four LC UPC duplex connectors, this harness provides an 8-fiber active path for switch ports, server NICs, and patch panels that still rely on LC interfaces, while supporting OS2 G.657.A1 bend-insensitive performance.
Factory-terminated and 100% tested, the MPO–LC harness delivers verified low insertion loss and high return loss for improved network integrity. It is ideal for transitioning from duplex-based 10G/25G Ethernet links to parallel 40G/100G Ethernet infrastructures, enabling seamless upgrades without a complete recabling of your physical layer. With a riser-rated OFNR jacket and compact breakout legs, it is well-suited for high-density cabling applications in data centers, equipment rooms, and telecommunication rooms where space, airflow, and cable management are critical.

Why Choose NSComm MPO 12F to 4xLC UPC Duplex Harness Cables?
-
Seamless duplex–parallel migration – Designed to bridge MPO-based backbones and LC-based switch or server ports.
-
High-density breakout design – One MPO trunk to four LC duplex legs reduces cable bulk in front-of-rack and top-of-rack layouts.
-
Low-loss, high-reliability performance – Factory-terminated and tested MPO and LC connectors help maintain tight optical budgets.
-
Bend-insensitive OS2 G.657.A1 fiber – Supports tight routing and compact cable management in crowded data center racks.
-
Crossover polarity for clean mapping – Pre-engineered polarity simplifies planning and reduces risk of mispatching.
-
Riser-rated OFNR construction – Suitable for in-cabinet routing and structured cabling in enterprise and cloud facilities.
Length Options
Standard stocked lengths:
Available in common harness lengths suitable for top-of-rack, middle-of-row, and end-of-row deployments, with optimized 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.
