## Long description

The EFB Elektronik O0381.3 3 m LC Yellow is a single-mode OS2 fibre optic patch cable designed for reliable, high-speed optical connections. With LC connectors on both ends and a 3 metre length, it provides a low-loss link for full duplex communication between networking devices. The cable's 9 µm core diameter supports long-distance single-mode transmission and the yellow jacket offers standardized colour coding for easy identification in structured cabling environments.
Advantages
This LC–LC single-mode cable minimizes signal attenuation and supports precise alignment for stable data transfer. The 3 m length is suitable for common rack-to-rack, patch panel, and equipment-to-equipment connections without introducing unnecessary slack. The yellow outer jacket provides clear visual distinction for single-mode infrastructure, and the LC connectors offer compact form factor and dense port compatibility.
Suitable for
 Connecting switches, transceivers and patch panels in data centres and telecommunications rooms
 Establishing full duplex links between network devices requiring single-mode transmission
 Structured cabling installations where standardized colour coding is used
 Laboratory setups and test benches requiring short to medium single-mode fibre runs
Key specifications
 Fibre type: single-mode (OS2)
 Connector type: LC to LC, duplex
 Length: 3 m
 Core diameter: 9 µm
 Jacket colour: yellow (single-mode standard)
 Transmission: full duplex optical link
How to use
Inspect connector endfaces for dust or damage before installation and, if necessary, clean with appropriate fibre cleaning tools. Gently insert each LC connector into the corresponding LC port until it clicks, ensuring correct orientation and avoiding excessive bending of the cable. Route the cable along cable management channels or trays to prevent tight bends and mechanical strain. For removal, depress the LC latch and pull straight out to avoid damaging the connector ferrule.
Usage recommendations
Store and handle the cable following industry best practices: avoid bends sharper than the specified minimum bend radius, protect connector endfaces from contamination, and use patch panels or pigtail adapters where frequent plugging is required. For critical links, test insertion loss and continuity after installation to verify performance.
