ACT 1 meter Singlemode 9/125 OS2 Polarity Twist fiber cable with LC connectors

The ACT Singlemode Fiber Cable 1m LC-LC 9/125 OS2 Polarity Twist is a 1-meter duplex optical patch cable designed for singlemode networks. It features LC connectors on both ends and a 9/125 µm core/cladding structure with OS2-grade fiber, providing low attenuation and stable signal transmission for long-reach links in data centers, telecom rooms, and campus backbones.

Advantages

This LC-LC singlemode cable delivers low insertion loss and high return loss characteristics typical of OS2 fibers, supporting long-distance transmission with minimal signal degradation. The polarity twist configuration simplifies duplex pair management in patch panels and active equipment, reducing the risk of cross-connection. The compact LC connectors allow high-density port arrangements while maintaining reliable physical contact and repeatable performance.

Suitable for

• Data center interconnects and cabinet patching
• FTTx distribution and backbone links
• Telecom equipment connections and optical transceivers
• Laboratory testing and fiber patching in enterprise networks

Key specifications

• Fiber type: Singlemode OS2
• Core/cladding diameter: 9/125 µm
• Connector type: LC to LC (duplex, polarity twist)
• Cable length: 1 meter
• Typical attenuation: low typical loss for OS2 fibers (optimized for long reach)
• Jacket: slim, suitable for high-density routing

How to use

Connect the LC connectors to the corresponding LC ports on patch panels, optical transceivers, or network devices, ensuring correct duplex orientation as required by your equipment. The polarity twist arrangement alternates the fiber pair to match transmit and receive channels; verify link continuity and loss with an optical power meter or visual fault locator when installing or testing. Route the cable through cable managers or trays to avoid excessive bending and secure it to prevent strain on the connectors.

Recommendations

Handle the LC connectors by the boot and avoid touching the ferrule endface. Clean connector endfaces before mating, follow the minimum bend radius specified for singlemode fiber, and store or deploy the cable in environments within recommended temperature and humidity ranges to maintain optical performance.
