Sklolaminátový kábel EFB Elektronik O2003.20 20 m ST žltý

The EFB Elektronik O2003.20 is a 20 m OS2 fibre optic cable with ST connectors on both ends and a 9 µm core diameter. Designed for long-distance, high-speed data transmission, this yellow patchcord is suitable for structured cabling installations where a short, direct connection between a passive interface and an active device port is required. The cable complies with common structured cabling concepts and is compatible with network environments that use LC, SC, E2000® and MPO/MTP connectors alongside ST when necessary.

Advantages

This fibre optic cable provides low attenuation over long distances due to its OS2 single-mode construction and 9 µm core. ST connectors on both ends offer reliable mechanical coupling and are widely used in legacy and current networking equipment. The 20 m length allows flexible placement of devices in data centres and network racks while the yellow jacket ensures easy identification within cabling bundles.

Suitable for

• Long-distance single-mode links in data centres and telecom rooms
• Connections between passive interfaces and active device ports (patching)
• InfiniBand and other high-speed network applications that accept ST connectors
• Environments requiring clearly colour-coded cable management

How to use

Route the cable between the passive interface (for example, a patch panel) and the active device port (such as a switch, router or transceiver module) ensuring gentle bends and avoiding sharp kinks. Insert and secure the ST connectors into the appropriate ceramic or metal receptacles until the bayonet coupling locks. Verify link integrity and optical power levels using appropriate test equipment after installation.

Recommendations

Use the cable within recommended bend radius limits, keep connectors dust-free with protective caps when not in use, and label both ends for easy identification during maintenance and troubleshooting.
