Fibre optic cable EFB Elektronik O0312.5 5m LC Blue

The EFB Elektronik O0312.5 is a 5 m OM3 fibre optic cable with LC connectors on both ends, designed for full-duplex high-speed data transmission. With a 50 µm multimode core and standardized OM3 performance, this blue-coded cable supports short to medium distance links in structured cabling, server rooms and data centres. The cable is produced by EFB Elektronik, a manufacturer with long experience in fibre and copper infrastructure and production in Germany and parts of Europe.

Advantages

This 5 m OM3 LC–LC cable provides reliable multimode transmission with a 50 µm core suitable for 10 Gbit/s and other high-bandwidth applications over typical OM3 distances. The LC connectors on both ends ensure compact, duplex-ready connections compatible with standard networking equipment. The blue jacket aids visual identification and cable management in patch panels and cabling installations.

Suitable for

• Interconnections in data centres and server rooms
• Patch panel to switch or transceiver connections
• High-speed multimode links (10 Gbit/s and compatible systems)
• Structured building cabling and fiber management installations

Key specifications

• Length: 5 m
• Fibre type: OM3 multimode
• Core diameter: 50 µm
• Connector type: LC to LC, duplex
• Jacket colour: Blue

How to use

Connect each LC connector into the corresponding LC duplex ports on your network equipment, patch panel or transceiver module. Ensure the connectors are clean and free from dust before mating; use appropriate dust caps or a fibre cleaning tool if available. Route the cable without excessive bending and secure it within cable management to maintain minimum bend radius and prevent strain on the connectors. For duplex operation, maintain correct orientation to preserve transmit/receive pairs.

Recommendations for use

Inspect and clean LC endfaces before insertion, avoid tight bends and long-term mechanical stress, and verify link performance after installation to confirm expected bandwidth and signal integrity.
