OS2 ST – ST Single-Mode Duplex Fiber Jumper Cable — 3.0mm Yellow Jacket
Single-Mode Fiber Patch Cable
This OS2 ST to ST single-mode duplex fiber jumper cable is engineered for ultra-low-loss, long-haul applications where signal integrity and distance matter. Built with a 9/125µm single-mode core, precision-polished UPC ST connectors, and a durable 3.0 mm yellow jacket, this duplex cable is ideal for telecom infrastructure, enterprise backbone links, data center interconnects, CATV networks, and campus fiber runs.
Why this cable matters
- OS2 single-mode performance — Optimized for 1310 nm and 1550 nm wavelengths in long-distance optical networks.
- Duplex ST/ST connectivity — Supports simultaneous transmit and receive optical communication in legacy ST-based environments.
- Low-loss optical performance — UPC-polished ferrules help deliver low insertion loss and high return loss for dependable signal transmission.
- Durable 3.0 mm PVC jacket — Flexible and easy to route for clean cable management in racks, cabinets, and pathways.
- Factory tested — 100% inspected for attenuation, end-face quality, and tensile strength before deployment.
