US Patent 11953745 Fiber optic cable transition tube

A transition tube is provided for receipt of a fiber optic cable with a jacket portion and a stripped fiber portion. The transition tube allows the optical fiber to be placed within a gel block seal so that the gel block need not contact the jacket of the optical fiber cable. In some examples, the transition tube contains inner geometry to allow easy insertion of an optical fiber cable. In other examples, an end of the cable is sealed within the transition tube.
