LC Series

The LC connector is a small form-factor (SFF) fiber optic connector with RF-45 style interface and resembles a small SC connector. The push-pull latching mechanism provides quick insertion and removal while also ensuring a positive connection.
The LC series connector is available in the Physical Contact (PC) pre-dome ferrule endface as well as the Angled Physical (APC) ferrule endface with 8 degree angle for applications where reduced back reflection is desired. The connector can be made with custom inside diameters to fit large core fibers.
