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.

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.

A splice for connecting two segments of optical fiber cable, the splice comprising: (a) an elongated housing having a first end with a first opening, a second end with a second opening, and a central cavity, the housing being essentially seamless between the first and second ends; (b) a clamping mechanism disposed in the central cavity and comprising at least a platform defining a fiber-receiving channel open to both first and second openings, a first member adjacent to the fiber-receiving channel and having at least one cam surface, and a second member having a second cam surface, the first and second cam surfaces cooperating such that relative movement of the first and second members toward the first end causes the first member to move toward the fiber-receiving channel and an actuator to cause relative movement of the first and second members toward the first end; (c) a first buffer crimp disposed at the first opening; and (d) a second buffer crimp disposed at the second opening.

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.

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.
摘要:
A method of terminating a fiber in a connector having a front and rear orientation, a housing, a clamping mechanism in the housing, and a ferrule assembly forward of the clamping mechanism and comprising a holder and a ferrule extending from the holder, the method comprising covering the ferrule with a cap, inserting a fiber into the clamping mechanism from the rear of the connector, and while the cap is on the ferrule, actuating the clamping mechanism to secure the fiber to the connector by urging the cap rearward relative to the clamping mechanism.
摘要:
A method of qualifying a ferrule assembly as being adequate to make physical contact upon application of a certain mating force, said ferrule assembly comprising a ferrule having an mating face and two or more fibers in said ferrule extending from said mating face, said method comprising (a) determining a coplanarity line of the ends of said fibers of said ferrule assembly, (b) determining minus coplanarity, said minus coplanarity being the greatest parallel offset between said coplanarity line and a fiber end below the coplanarity line; and (c) determining whether said ferrule assembly will make physical contact as a function of at least said minus coplanarity and said certain mating force.
