How to use
Inspect both ends of the cable and the device ports for cleanliness before installation. Align the LC connectors with the corresponding ports and insert gently until a secure latch click is felt. Route the cable according to your rack or cable-management plan to avoid excessive bending; maintain the manufacturer’s recommended minimum bend radius for single-mode fibre to prevent signal degradation. For removal, depress the LC latch and pull straight out to avoid damaging the connector or port.
Usage recommendations
Use appropriate fibre cleaning tools or wipes before connecting to remove dust or contaminants. Avoid tight bends, crushing, or stepping on the cable and label both ends for easy identification. For installations in structured cabling, follow industry standards for fibre handling and maintain service loops where necessary to allow for future moves or re-termination.
