## Long description

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
