Abstract: A connector is provided to align two optical fiber cables with one another so that a light signal may be transmitted from one to the other with minimum loss. One section of the connector has a tapered elastic member in the form of a compressible cone in which the opposed ends of the two optical fiber cables are positioned. After the two sections of the connector are physically united, a cone lock supported from the other section of the connector is moved over the compressible cone, collapsing the latter about the adjacent optical fiber ends and sealing the resultant aligned connection from external influences.
