Methods for sealing fiber optic cables entering the equipment room

The most common fiber splice closure sealing methods include heat-shrink, mechanical, and gel-based sealing. Gel seals utilize a soft gel material that adheres tightly to the cable. One simple and effective way to protect these systems in land, sea, air and space environments is to make sure they are properly sealed against the environment with the help of hermetic epoxy-based sealing technologies. However, the sealing method used inside these closures largely determines the long-term reliability of the fiber connection. Every fiber optic cable has a specified minimum bend radius. Cable entry seals are protective barriers designed to safeguard cables where they pass through walls, enclosures, or equipment panels.
