OS2 LC/APC – ST Single-Mode Duplex Fiber Jumper Cable — 3.0mm Green Jacket Single-Mode Fiber Patch Cable Our 3 mm OS2 LC/APC to ST single-mode duplex fiber jumper is engineered for ultra-low-loss, long-haul optical networking. Featuring a precision 9/125 µm single-mode fiber core and angled physical contact APC polish, this green-jacketed cable delivers exceptional signal integrity over extended transmission distances. Key Features OS2 Single-Mode Fiber — Optimized for 1310 nm and 1550 nm wavelengths used in long-distance optical transmission. LC/APC to ST Connectors — APC polish significantly reduces back-reflection (≥ 65 dB return loss) and minimizes insertion loss (≤ 0.3 dB). Reduced Back-Reflection — APC connectors greatly reduce optical return loss for sensitive high-speed digital and analog transmission systems. Enhanced Signal Quality — APC polish mitigates reflected signals, enabling higher-bandwidth optical communication. 3 mm PVC Jacket — Durable and flexible outer sheath designed for easy cable routing and cable management. Factory-Tested — 100% inspection for attenuation, connector end-face quality, and tensile strength. Wide Temperature Range — Rated for –20 °C to 70 °C indoor and outdoor operation. RoHS Compliant — Environmentally responsible materials. Performance Specifications Parameter Specification Core / Cladding Diameter 9 µm / 125 µm Maximum Attenuation (1310 nm) ≤ 0.40 dB/km Maximum Attenuation (1550 nm) ≤ 0.30 dB/km Minimum Return Loss ≥ 65 dB (APC) Operating Bandwidth Up to 10 Gbps and beyond Maximum Link Length 10 km (1310 nm) • 40 km (1550 nm) Typical Applications Long-distance telecommunications Data center interconnects Enterprise backbone networks CATV and metro-access networks Campus and building riser installations Quick Note Unlike multimode fiber (OM1–OM4), which is designed for shorter campus links (typically up to 550 m), OS2 single-mode fiber supports extremely long transmission distances with minimal signal loss. This makes it ideal for carrier networks and high-capacity data-center backbone links.
