## Summary description

The EFB Elektronik O2561.5 is a 5m OS2 fibre optic cable with SC connectors on both ends. It features a core diameter of 9 µm and supports full duplex communication, ensuring high-speed data transmission with minimal signal loss. Ideal for data centers and high-performance networking applications.

## Long description

The EFB Elektronik O2561.5 5m SC Yellow is a single‑mode OS2 fibre optic patch cable designed for reliable, low‑loss data transmission in structured networks. With SC connectors on both ends and a 9 µm core diameter, this 5‑metre cable supports full duplex links and is suited for high‑speed backbone connections and inter-rack cabling in data centers and telecommunications environments.
Advantages
This fibre optic cable offers low attenuation and stable optical performance for single‑mode applications, ensuring consistent signal integrity over the 5‑metre length. The standardized SC connectors provide secure, easy insertion and removal, while the yellow jacket indicates single‑mode OS2 classification for straightforward identification during installation and maintenance. The cable construction minimizes return loss and supports full duplex communication for simultaneous transmit and receive channels.
Suitable for
 Data center patch panels and inter‑rack connections
 Telecommunications backbone and point‑to‑point links
 High‑performance networking equipment requiring single‑mode fibre
 Laboratory and test setups that need standardized SC connections
Key specifications
 Fiber type: single‑mode OS2
 Length: 5 m
 Connector type: SC–SC (both ends)
 Core diameter: 9 µm
 Jacket color: yellow (single‑mode identification)
 Duplex support: full duplex
 Typical use: indoor/patch cabling
How to use
Confirm that both ends of the network devices or patch panels accept SC connectors and that single‑mode fibre is the correct medium for the link. Route the cable avoiding sharp bends and excessive tension; observe the minimum bend radius recommended for single‑mode cables. Insert the SC connectors straight into the corresponding adapters or transceivers until they click or seat firmly. For best performance, keep connector endfaces clean—use approved fibre cleaning tools or wipes before connection. After installation, verify link integrity and optical power levels with appropriate test equipment.
Usage recommendations
Store the cable coiled loosely and avoid crushing or prolonged exposure to direct sunlight. When routing in trays or conduits, maintain separation from electrical power cables to reduce potential interference in mixed-cable environments. For critical links, perform periodic inspection and endface cleaning to preserve low insertion loss and return loss characteristics.
