Enable Seamless Connectivity for Your Network
Network-Switch.com offers the ability to configure the pre-set compatibility of either connector of the AOC cable online with NS BOX to connect Cisco to Arista, Dell to Juniper, and any other mixes of configurations.
Overview
The NS 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 NS 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.
