## Summary description

The ACT 20 meter Singlemode 9/125 OS2 Polarity Twist fiber cable features a core diameter of 9 µm and is equipped with 2 LC connectors on each end. This high-quality fiber optic cable is designed for reliable data transmission over long distances, making it ideal for networking and telecommunications applications. Its OS2 specification ensures low attenuation and high performance, while the polarity twist design helps maintain signal integrity.

## Long description

The ACT 20 meter Singlemode 9/125 OS2 Polarity Twist fiber cable is a 20 m singlemode optical patch lead with a 9 µm core diameter and OS2 specification. It is fitted with LC connectors on both ends (2 LC connectors per end), and its polarity twist design helps preserve correct channel orientation in duplex links. The cable is intended for long-distance, low-loss data transmission in optical networks and telecommunication systems where singlemode performance and controlled polarity are required.
Advantages
This fiber cable delivers low attenuation and stable transmission characteristics thanks to the OS2-grade singlemode fiber and the 9/125 µm core/cladding geometry. The LC connectors provide a compact duplex interface with reliable mating performance, and the polarity twist feature reduces the need for manual re-patching when aligning transmit and receive channels. The 20 m length offers flexibility for rack-to-rack or room-to-room connections while maintaining signal integrity over extended runs.
Suitable for
 Data centre interconnects and rack-to-rack patching
 Telecommunications backbone links and campus networks
 Fiber patch panels and optical distribution frames
 Long-reach singlemode installations requiring controlled polarity
Key specifications
 Length: 20 meters
 Fiber type: Singlemode
 Core/cladding diameter: 9/125 µm
 Optical grade: OS2 (singlemode long-distance)
 Connector type: LC duplex on each end
 Polarity: Twist design for duplex polarity management
 Typical use: Patch cable for optical networks and telecommunication equipment
How to use
Install the ACT 20 m singlemode fiber cable by connecting the LC duplex connectors to corresponding LC ports on patch panels, transceivers or optical equipment. Ensure connectors are clean before mating to minimize insertion loss; use appropriate fiber cleaning tools if necessary. Route the cable following recommended bend radius limits and secure it with cable management accessories to avoid stress on the connectors. Verify correct polarity and link continuity with an optical tester or by checking signal presence after connection.
Usage recommendations
To maintain performance, store and handle the cable in a dust-free environment, avoid excessive bending or kinking, and clean connector endfaces before each connection. Use the polarity twist feature when deploying duplex links to simplify alignment of transmit and receive pairs and reduce configuration time during installation.
