Features
Build a Stable and Robust Fiber Optic Network
High-quality tight-buffered cable protects the fibre optic core, and increases the strength and durability of the fibre.
Carrier-grade Cable Ensures Transmission Quality
Superior cable assemblies reduce light loss and easily meet your diverse cabling requirements.
Color-Coded Cable Jacket
A fibre cable's jacket colour is typically defined by the fibre type, and can differ based on mode and performance level.
A-to-B Fiber Polarity in Fiber Applications
To help the industry select and install the right components to maintain proper polarity, TIA-568-C standards recommend the A-B polarity scenario for duplex patch cords.

Overview
The NS ST UPC to ST UPC Duplex Single Mode Fiber Patch Cable is a rugged OS2 interconnect solution designed for long-distance links in entrance facilities, telecommunications rooms, data centers, and industrial or legacy ST-based environments. Featuring ST UPC duplex connectors on both ends with bayonet-style coupling, this cable provides secure, quick-connect terminations ideal for applications where frequent mating and robust mechanical engagement are required.
Constructed with bend-insensitive G.657.A1 fiber and a 2.0mm riser-rated (OFNR) tight-buffered jacket, this duplex patch cable delivers low insertion loss, high return loss, and consistent performance even when routed through tight spaces. It supports 1G/10G/25G/40G/100G/400G Ethernet connections and is well-suited for long-distance transmission—up to 10 km at 1310 nm or up to 40 km at 1550 nm—making it an excellent choice for single mode backbones, cross-connects, and point-to-point links.
