About Light-Seal

Light-Seal® is FiberFin’s connector technology that swages the end of the connector to secure and align the fiber concentrically to the outside of the connector ferrule, ensuring minimal lateral fiber offset when the connector is mated to a receptacle.

In the connector, fiber is held in place independently from the cable’s jacket, preventing pistoning between the fiber and connector assembly. This eliminates the need for adhesives, making for a simple field installation process. This design also minimizes the potential for contaminants to enter the connector between the fiber and connector hole.

Light-Seal® is covered by U.S. patent number 6,517,255.
