Abstract

An optical fiber cable unit in which an elongated optical fiber is telescoped into an outer jacket such that an annular space is defined between the fiber and the jacket. The space is filled with a polyorganosiloxane "grease" having extremely good thixotropic properties which cause the material to establish a gas-tight seal between the fiber and the jacket while allowing the fiber to float freely within the jacket to avoid elongation of the fiber when tension is applied to the cable.
