Fibre optic cable EFB Elektronik O2561.20 20 m SC Yellow

The EFB Elektronik O2561.20 is a 20 m single-mode OS2 fibre optic cable with SC connectors on both ends. With a 9 µm core diameter, this fibre jumper is intended for high-speed, long-distance connections in structured cabling systems and follows common terminology for patchcords used as the shortest link between a passive interface and an active device port. The cable's yellow jacket provides easy visual identification in network installations.

Advantages

The SC‑terminated OS2 fibre offers low attenuation for long-distance data transmission and stable optical performance. A standardized fibre jumper form factor ensures compatibility with common network equipment and passive infrastructure. The 20 m length provides flexibility for routing between racks or equipment without splicing.

Suitable for

• Data centre trunk or inter-rack connections
• Long-distance single‑mode links in enterprise or campus networks
• Connections between passive patch panels and active devices with SC ports

How to use

Route the fibre cable without sharp bends or kinks and secure it with appropriate cable management to maintain minimum bend radius specified by the cabling standard. Insert the SC connectors firmly into compatible sockets on patch panels or device ports until they click. Avoid touching the fibre endfaces; clean connectors with proper fibre cleaning tools before mating to ensure optimal optical performance.

Usage recommendations

Use this OS2 SC fibre jumper for long-distance single‑mode links and in environments where clear colour coding is required. Store and handle the cable to avoid excessive bending and contamination of connector endfaces; clean connectors before use and verify link performance with suitable optical test equipment if required.
