OS2 ST – ST Single-Mode Simplex Fiber Jumper Cable — 3.0mm Yellow Jacket
Single-Mode Fiber Patch Cable
This OS2 ST to ST single-mode simplex fiber jumper cable is engineered for ultra-low-loss, long-haul optical applications where signal integrity and distance matter. Built with a 9/125µm single-mode core, durable 3.0 mm yellow jacket, and precision ST connectors on both ends, this cable is ideal for telecom infrastructure, enterprise backbones, 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 fiber applications.
- Simplex ST/ST connectivity — Ideal for single-strand optical links and legacy ST-based fiber equipment.
- Low-loss optical performance — UPC-polished ferrules support low insertion loss and high return loss for reliable signal transmission.
- Durable 3.0 mm jacket — Flexible, easy to route, and built for dependable cable management in racks, cabinets, and pathways.
- Factory tested — Inspected for attenuation, end-face quality, and tensile strength before deployment.
