## Long description

The EFB Elektronik O0381.20 is a 20 m OS2 single-mode fibre optic cable with 2x LC connectors on each end, designed for full duplex data transmission. Featuring a 9 µm core diameter and a yellow outer jacket, the cable is intended for long-distance, low-loss signal delivery in structured networks. Its compact LC connectors and single-mode construction provide consistent performance for applications that require reliable high-speed links and optical integrity over extended runs.
Advantages
This OS2 single-mode fibre offers low attenuation and stable signal quality over long distances, reducing the need for repeaters or signal boosters. The 2x LC connector configuration supports full duplex operation and a compact form factor suited to high-density patch panels. The 20 m length provides flexibility for rack-to-rack or equipment-to-equipment connections in server rooms and data centers, while the yellow jacket makes the cable easy to identify among other network cabling.
Suitable for
Data center rack-to-rack connections
Backbone links in enterprise LANs
High-performance networking between switches and fiber transceivers
Long-distance optical runs within buildings or campus environments
Key specifications
Fiber type: OS2 single-mode
Length: 20 m
Core diameter: 9 µm
Connector type: 2x LC to 2x LC
Duplex: Full duplex
Jacket color: Yellow
How to use
Route the cable along cable trays or through conduits to avoid tight bends and mechanical stress. Ensure connectors are free of dust before mating by inspecting or cleaning with appropriate fibre cleaning tools. Plug the LC connectors into matching LC ports on transceivers, patch panels or network equipment, confirming correct alignment for duplex pairs. Avoid kinking the cable and maintain the manufacturer’s minimum bend radius during installation and while in service.
Usage recommendations
For optimal performance, store and install the fiber in a dry, temperature-controlled environment and use recommended fibre cleaning materials before connecting. Label both ends to simplify maintenance and testing, and perform insertion loss and continuity tests after installation to verify link quality.
