摘要： A method for preparing a ferrule assembly avoids polishing while providing adequate control over fiber end protrusion and co-planarity. A distal end of the fiber is prepared before securing the fiber in a ferrule, and before or after inserting the fiber into the ferrule. The prepared fiber is manipulated to provide a desired spatial relationship between the fiber end and the ferrule's end face, and then secured to maintain the desired spatial relationship. Preferably, the fiber end is prepared using a laser cleaving technique to provide a suitable end without abrasive polishing. An interferometer may be used to obtain measurements, during manipulation of the prepared fiber within the ferrule, that indicate whether the prepared fiber is satisfactorily positioned. In accordance with other aspects of the invention, a ferrule assembly prepared in accordance with the method, and a connector or other optical package including such a ferrule assembly are provided.

摘要： An optical connector which is suitable for connection to jacketed cable includes a housing and a ferrule assembly. The ferrule assembly includes a front portion having a first geometry, and the housing includes a receiving portion having a second geometry that mates with the first geometry to prevent rotation of the ferrule assembly relative to the housing. A spring biases the ferrule assembly forward to assist mating of the first and second geometries.

摘要： A bend limiter for use with electrical and fiber optic cables that can handle a relatively wide range of side loading without excessive bending is disclosed. The bend limiter is configured to bend at radii which are less than the critical curvature of the cable over a range of loads. The bend limiter includes a flexible member having two portions. One portion has a non-linear profile and is designed to absorb high loads to control bending. The other portion has a tapered linear profile and is designed to bend under light loads so that a conductor at the tip of the bend limiter does not kink.

摘要： The invention is a protective enclosure that can be adapted for use with different types of connectors, including LC type fiber optic connectors. The protective enclosure includes a plug portion and an adapter portion. The plug portion includes a plug housing having an internal longitudinal bore adapted to accept a plug connector of a connector type larger than an LC adapter, but includes a clip to which one or two LC plug connectors can be fixedly mounted that can optionally fixedly clip into the internal bore of the housing so that an LC connector can be fixedly mounted within the housing. The adapter portion includes an adapter housing having an internal longitudinal bore adapted to accept an adapter connector of a connector type larger than an LC adapter, but including an optional sleeve that can fixedly snap into the internal bore of the adapter housing and within which an LC adapter connector can be fixedly mounted.
