Fibre optic duplex patch cable EFB Elektronik LC–LC 0.5 m OM4 50/125 µm violet

Duplex fibre optic patch cable EFB Elektronik LC–LC, 0.5 m, OM4 (50/125 µm) with violet jacket. The cable provides a ready‑made duplex connection with LC connectors on both ends and OM4 multimode fibre suitable for short‑range, high‑bandwidth links in data centres, server racks and optical patch panels. The violet outer sheath allows easy visual identification of the cable type.

Advantages

The LC–LC duplex patch cable offers OM4 multimode performance for higher bandwidth and improved modal dispersion characteristics on 50/125 µm fibre. With a compact LC connector form factor and a 0.5 m length, it is suitable for neat cable management in racks and patch panels. The violet jacket enables quick visual sorting and identification in dense cabling environments. The product is manufactured by EFB Elektronik, a long‑standing European supplier with production in Germany and parts of Europe.

Suitable for

• Short‑range high‑speed links in data centres
• Interconnections within server racks and between patch panels
• InfiniBand and other duplex multimode applications
• Laboratory and testing setups requiring OM4 multimode fibre

How to use

Ensure both patch panel or transceiver ports are LC‑type and rated for multimode fibre. Remove any dust caps from the LC connectors and inspect endfaces for contamination; clean with appropriate fibre cleaning tools if necessary. Insert each LC connector into the corresponding port until it clicks. For duplex operation, align transmit and receive fibres according to the port labelling. Avoid tight bends and secure the cable to prevent strain on connectors.

Recommendations

For reliable performance, use the LC–LC OM4 duplex cable within recommended multimode link distances and follow standard fibre handling procedures: keep connector endfaces clean, avoid bending below the fibre’s minimum bend radius and maintain proper strain relief. Use the violet jacket to mark OM4 multimode runs in your cabling documentation.
