LC - LC singlemode fiber assemblies provide precise optical connectivity for long distance network links in enterprise, telecom, and carrier grade systems. These cables support gigabit and 10 gigabit transmission over 9/125um singlemode fiber with low attenuation and stable performance across extended ranges. Duplex LC connectors ensure secure mating and consistent signal integrity for WAN backbones, data center interconnects, and high bandwidth routing. Assemblies are built for reliable, high performance operation in professional singlemode fiber environments.
