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.
Usage 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.
