Fibre optic cable EFB Elektronik O0381.7,5 7.5 m 2x LC Yellow

The EFB Elektronik O0381.7,5 is a 7.5 m OS2 single-mode fibre optic patch cable with LC connectors on both ends in a duplex configuration. Designed for reliable point-to-point links, this yellow cable uses a 9 µm core diameter to support single-mode transmission and full-duplex data flow. It is intended for structured cabling in data centres, server rooms and network installations where low attenuation and stable optical performance are required.

Advantages

This fibre optic cable provides low insertion loss and consistent single-mode propagation thanks to the 9 µm core. The duplex LC connector arrangement enables simultaneous transmit and receive channels over a compact connector type, saving rack and panel space. The OS2 fibre specification makes the cable suitable for longer runs with reduced signal degradation. The yellow jacket allows easy visual identification within mixed cable environments, and the cable jacket is constructed for durable handling in installation and maintenance scenarios.

Suitable for

• Interconnecting network switches and servers in data centres
• Patch panels and fibre distribution frames
• High-speed backbone links within enterprise networks
• Point-to-point links in telecommunication racks

Key specifications

• Fibre type: OS2 single-mode
• Length: 7.5 m
• Connector type: LC to LC, duplex (2x LC)
• Core diameter: 9 µm
• Jacket colour: yellow
• Transmission: full duplex

How to use

Connect each LC connector into the corresponding LC adapter or port on transceivers, patch panels or network devices, observing correct polarity for transmit and receive channels. Route the cable without sharp bends and maintain the minimum bend radius specified by the installation environment to avoid increased attenuation. For long-term installations, secure the cable with appropriate cable management to prevent strain on the connectors.

Recommendations

Before installation, verify transceiver compatibility and clean LC endfaces with appropriate fibre cleaning tools to ensure optimal optical performance. Avoid kinking the cable and protect exposed connectors with dust caps when not connected.
