5M ST-LC SM OS1/OS2 Duplex Patch Lead

The 5 m ST-LC SM OS1/OS2 Duplex Patch Lead is a high-performance single-mode fibre optic cable engineered for reliable full-duplex connectivity in telecommunications, data centres, and structured cabling environments. Featuring ST connectors on one end and LC connectors on the other, this duplex patch lead enables efficient interconnection between patch panels, optical transceivers, and network devices.

Constructed with 9/125 µm single-mode fibre, the cable ensures long-distance high-speed transmission with minimal signal loss. Its duplex configuration contains two fibre strands within a single cable, allowing simultaneous transmit and receive communication for full-duplex network operation. Precision-polished ceramic ferrules provide low insertion loss and stable optical performance.

The durable yellow LSZH or PVC jacket provides flexibility, protection, and easy identification of single-mode fibre in installations. With a compact 2 mm per strand diameter, this 5 m patch lead is simple to route and manage in high-density rack and cabinet setups.
