Fiber Jumper — OS2 Single‑Mode SC/ST (Duplex) • 9/125 µm • 1310/1550 nm • 3 mm • Yellow Long-haul OS2 | 9/125 µm • 1310/1550 nm • SC/ST duplex Engineered for ultra-low-loss, long-distance optical links, this 3 mm OS2 single-mode duplex fiber jumper features SC to ST duplex connectors, a 9/125 µm core, and a durable yellow PVC jacket for dependable handling and clean cable routing. Optimized for 1310 nm and 1550 nm, it is ideal for telecom, enterprise backbone, CATV, metro-access, and data-center applications where long reach and low attenuation matter. Typical Applications Long-distance telecommunications — dependable single-mode performance over extended runs Data center interconnects — low-loss links between cabinets, racks, and network equipment Enterprise backbone networks — clean optical connectivity for critical infrastructure CATV / metro-access networks — stable signal transport in single-mode fiber environments Campus / riser installations — ideal for building backbones and structured cabling runs Key Features OS2 single-mode fiber — optimized for 1310 nm and 1550 nm long-haul transmission SC/ST duplex connectors — precision-polished UPC ferrules for fast, reliable deployment Low insertion loss — rated at ≤ 0.3 dB for strong optical performance High return loss — ≥ 50 dB for cleaner signal integrity 3 mm PVC jacket — flexible, durable sheath for handling and cable management Factory tested — 100% inspection for attenuation, end-face quality, and tensile strength Wide operating range — reliable from –20°C to 70°C RoHS compliant — environmentally friendly materials Built in the USA — manufactured and tested to high quality standards Rack Shelves Cable Management Category Detail Product Type OS2 single-mode duplex fiber jumper cable Fiber Type Single-mode (OS2), 9/125 µm Connector Type SC to ST, duplex Wavelengths 1310 nm / 1550 nm Insertion Loss ≤ 0.3 dB Return Loss ≥ 50 dB Maximum Attenuation @ 1310 nm ≤ 0.40 dB/km Maximum Attenuation @ 1550 nm ≤ 0.30 dB/km Operating Bandwidth Up to 10 Gbps and beyond Maximum Link Length 10 km (1310 nm); 40 km (1550 nm) Jacket 3 mm PVC, yellow Temperature Range –20°C to 70°C Why choose OS2 single-mode? Unlike multimode fiber used for shorter campus-style links, OS2 minimizes modal dispersion and supports much longer runs with very low signal loss. That makes it an excellent choice for carrier, backbone, and data-center infrastructure where distance, consistency, and signal integrity are critical. Why buy from Gruber Backbone-ready — built for long-distance, low-loss single-mode infrastructure. Consistent optical performance — UPC-polished connectors support stable, repeatable results. Deployment-friendly — flexible 3 mm jacket and common SC/ST duplex ends simplify installation.
