ABSTRACT:
A terminus for a fiber optic cable includes a ferrule. An optic fiber of the cable passes through a central bore of the ferrule and is attached to a lens seated in a conical or cylindrical seat formed in an end surface of the ferrule by an epoxy. Preferably, the seat permits the lens to be recessed below the end surface of the ferrule. An inspection slot may be formed through the seat to allow a technician to inspect the state of the epoxy attachment. The ferrule may also include retaining features, such as an o-ring encircling a groove in the outer circumference of the ferrule or a metal sleeve crimped or otherwise attached to the ferrule to permit the ferrule to be easily attached to a cable retention sleeve, connector body or similar structure.
