Fibre optic cable EFB Elektronik O0381.0,5 0.5m 2x LC Yellow

The EFB Elektronik O0381.0,5 is a 0.5 m single-mode OS2 fibre optic patch cable with LC connectors on both ends in a duplex configuration. Designed for short interconnects, the cable uses a 9 µm core diameter and a yellow jacket for standard single-mode identification. It provides low-loss optical transmission suitable for network equipment interlinks, patch panels and optical transceivers where compact LC connectors and precise duplex orientation are required.

Advantages

This 0.5 m fibre optic cable offers the compact LC duplex connector format that saves space in high-density installations and reduces connector footprint on transceivers and patch panels. The OS2 single-mode construction with a 9 µm core minimises attenuation over typical short runs, supporting reliable full-duplex communication. The yellow sheath allows quick visual identification of single-mode cabling in mixed environments, simplifying cable management and reducing installation errors.

Suitable for

• Connecting single-mode transceivers and SFP/SFP+ modules over short distances
• Patching between network switches, routers and patch panels in data racks
• Interconnecting optical equipment in server rooms and telecom closets

Key specifications

• Length: 0.5 m
• Fibre type: single-mode OS2
• Core diameter: 9 µm
• Connector type: 2x LC duplex on both ends
• Configuration: full duplex
• Jacket colour: yellow (single-mode identification)

How to use

Align the LC duplex connectors with the corresponding LC ports on your transceivers, switches or patch panels and insert until they click into place. Ensure correct polarity for full-duplex links by matching the transmit and receive channels on each end. For removal, press the LC latch and pull straight out to avoid damaging the connector. Route the cable with gentle bends to maintain the minimum bend radius recommended for single-mode fibre and avoid tight loops or kinks.

Recommendations

Keep connector end faces clean and protected with dust caps when not in use; use proper fibre cleaning tools before insertion to maintain low insertion loss. Avoid excessive bending and mechanical stress, and secure the cable within racks or trays to prevent movement that could lead to attenuation or connector damage.
