Product Overview
The LC Fiber Optic Connector is a high-performance, small form factor fiber connector widely used in modern fiber optic communication networks. Designed for high-density fiber connections, it delivers excellent optical performance and reliability in telecom, data center, and enterprise network environments.
This connector supports single-mode and multimode fibers, including SM, MM, OM3, OM4, and OM5, and is available in LC UPC connector and LC APC connector polishing types to meet different optical transmission requirements.
Compatible with 0.9mm, 1.2mm, 2.0mm, and 3.0mm fiber cables, the LC connector is ideal for patch cords, fiber pigtails, and field termination assemblies. Each connector is manufactured with precision zirconia ceramic ferrules and undergoes insertion loss, return loss, and mechanical durability testing to ensure long-term reliability in telecom networks, FTTH deployments, and high-density data center infrastructures.
Thanks to its push-pull locking mechanism and compact design, the LC connector has become a standard interface for modern fiber networks.
