Abstract
Abstract A metal ferrule is attached to the end of an optic fiber, with the ferrule end and fiber tip coplanar. The ferrule and fiber are slidably mounted in a housing which incorporates a quick-release connecting catch, and are abutted by spring-loading against a mating optical device. The catch is adapted to engage a fitting secured to the mating optical device.
