The Optical Industrial LC Duplex connector system combines the high performance of a fiber optic connection with the versatility of a rugged industrial connector to allow for easy installations and terminations in harsh industrial environments. The connector system features assemblies with push-pull insertion and a bayonet-style mechanical latch to ensure an environmentally sealed optical connection in just one simple step. Its bulkhead adapter is designed with a sealed panel feed-through design for easy installation into enclosures. Plus, the removable connector provides sealing between both the adapter mating surface, as well as the cable exiting the connector.
