Abstract: A fiberoptic cable assembly is described with terminal connectors in which a coupling element encloses the fiberoptic fibers and has a sleeve portion over which the fiberoptic sheath is secured and a larger diameter hollow portion carrying discontinuities on its exterior surface for engaging a strain relief tubing. A cup washer is locked against the coupling element by a locking element that serves as the connecting terminal of the cable. The cup washer is designed so that its cupped portion encloses the end of the strain relief tubing and presses it into the discontinuities securing the tubing in place.
