:: What are LC Fiber Connectors?
LC connector was developed by Lucent Technologies and is a more evolutionary approach to achieving the goals of a SFF (small form factor) connector.
LC connector utilizes traditional components of a SC duplex connector having independent ceramic ferrules and housings with the overall size scaled down by one half.
The LC family of connectors includes a stand-alone simplex design; a “behind the wall” (BTW) connector; and the duplex connector available in both single mode and multimode tolerances, all designed using the RJ-style latch.
:: LC Connector Applications
The LC Connector Product is a robust optical connector designed to support Telecom and Datacom networks. The connector family includes but not limited to Jumper Connectors, Behind the Wall connectors (BTW), Adapters, Attenuators, Jumpers and an assortment of connector modules and panels.
The connector is defined as the plug portion equipped with a tunable cylindrical ferrule while incorporating unique trigger and latch features.
The LC Connector family provides a size reduction relative to traditional connectors, which has coined the term Small Form Factor connectors (SFF). SFF connectors are typically 50% smaller than standard SC and ST fiber products. The LC was designed to be a high performance SFF incorporating traditional technology, advances in latching systems, and versatile enough for both single mode and multimode fiber applications.
:: Types of LC Connectors and Their Respective Applications
LC connector comes in single mode and multimode tolerances. For single mode, it also features LC/UPC and LC/APC polish. LC/APC has a 8 degree angle to minimize back reflection and can be easily recognized by its green colored housing and strain relief boot.
