## Long description

The EFB Elektronik O0381.5 5 m LC Yellow is a single-mode OS2 fibre optic patch cable designed for high-speed, long-distance signal transmission. With LC connectors on both ends and a 9 µm core diameter, this 5 metre cable supports full duplex communication and is colour-coded yellow to simplify identification in structured cabling environments such as data centres and telecom racks.
Advantages
This fibre optic cable delivers low attenuation and stable optical performance suitable for single-mode applications. The LC connectors provide a compact footprint for high-density panels, while the 5 m length balances flexibility and reach for typical rack-to-rack or equipment-to-panel connections. The yellow jacket offers straightforward visual identification to reduce installation errors and speed up maintenance tasks.
Suitable for
Data centre patching and inter-rack connections
Telecommunications backbone links
High-performance computing clusters and server farms
Optical network equipment connections (switches, transceivers, patch panels)
Key specifications
Fibre type: Single-mode (OS2)
Connector type: LC to LC
Core diameter: 9 µm
Length: 5 metres
Duplex mode: Full duplex
Jacket colour: Yellow
How to use
Inspect connector endfaces for contamination and clean with approved fibre cleaning tools before insertion. Route the cable to avoid sharp bends; maintain the minimum bend radius recommended for single-mode fibres and secure the cable to cable management hardware to prevent strain on connectors. Insert the LC connectors into compatible ports on network devices or patch panels until they click. For full duplex links, ensure proper pairing of transmit and receive ports on both ends.
Usage recommendations
Store and handle the cable in a dust-free environment and use dust caps when connectors are not in use. When planning installations, allow service loops and avoid tight bends to preserve optical performance. Use this single-mode OS2 cable for long-reach or high-bandwidth applications where low attenuation and precise identification are required.
