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.

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.
