Fibre optic cable EFB Elektronik O0350.40 40 m LC Yellow

The EFB Elektronik O0350.40 40 m LC Yellow is a single-mode OS2 fibre optic cable designed for long-distance, low-loss signal transmission. With a 9 µm core diameter and LC connectors on both ends, this yellow cable is intended for reliable connections in networking environments and data center infrastructures. The jacket and connector assembly are made to withstand routine installation and patching while maintaining optical performance over its 40 m length.

Advantages

This single-mode OS2 fibre cable offers low attenuation and stable signal integrity across longer runs thanks to its 9 µm core. LC connectors provide a compact, standardized interface suitable for high-density patch panels and transceivers. The yellow outer jacket improves visual identification in cable trays and racks. The 40 m length reduces the need for multiple patch points and helps maintain consistent optical performance between equipment.

Suitable for

• Interconnection between network switches and optical transceivers within racks or between adjacent rooms
• Data center patching and fiber backbone connections
• Telecommunications links and campus network runs requiring single-mode fibre
• Laboratory and test environments where stable, low-loss single-mode links are needed

Key specifications

• Fiber type: Single-mode (OS2)
• Length: 40 m
• Core diameter: 9 µm
• Connectors: LC on both ends
• Outer jacket color: Yellow
• Design: Duplex/patch cable suitable for high-density panel use

How to use

Inspect connector endfaces for dust or debris before connection and clean with a suitable fiber cleaning tool if necessary. Route the cable along a protected path avoiding sharp bends; maintain bend radii recommended for single-mode fibre to prevent increased attenuation. Insert LC connectors into compatible transceivers, patch panels, or adapters until they click into place. When disconnecting, press the LC latch and pull straight out to avoid damaging the ferrule.

Recommendations

For optimal performance, avoid tight bends and excessive tension on the cable. Use dust caps when connectors are not in use and perform regular inspection and cleaning of connector endfaces. Choose this 40 m LC single-mode cable for runs where OS2 performance and compact LC connectors are required; verify transceiver compatibility and alignment for chromatic and modal matching in the link design.
