The invention relates to a process for mounting an optical fiber, in a connector element comprising a body having a frontal end surface which defines a plane of reference, and comprising a ferrule accommodated in said body, projecting axially toward the front and having a frontal end face which is located at a predetermined axial distance from said plane of reference. After the end of an optical fiber is stripped, it is mounted from the rear so that it projects axially from the frontal end (8a) of the ferrule (8); the non-stripped part of the optical fiber is immobilized at the rear of the body; the axial relative position of the stripped part of the fiber with respect to the frontal face of the ferrule is modified by a mechanical constraint exerted on either the fiber or the ferrule, by means of an appropriate tool positioned in a precise manner with respect to the plane of reference; a scratch is made in or in front of the plane of the frontal face of the ferrule; the fiber is fractured at the location of the scratch; and the fiber or the ferrule is allowed to return elastically. u

Process for mounting an optical fiber in an optical-fiber connector

A device makes a non-permanent connection between two optical fibers each fixed into a respective fiber holding device from which a bared end of the fiber protrudes. The device comprises a socket member featuring a guide member to accommodate the aligned bared fiber ends. A clamp member in line with the guide member immobilizes the bared fiber ends by clamping them against the guide member. Two mobile plug members are each adapted to interlock nesting fashion with the socket member, one on each side of the guide member. Their axes are at a predetermined angle to the guide member. Each plug member comprises a front surface through which it comes into an abutting and supporting relationship with the other plug member. At a rear end of a central channel in the plug member is a receptacle for the fiber holding device. There is an orifice at the front end of this channel slightly larger than the diameter of the bared fiber end. The length of the central channel is sufficient to allow part of the bared fiber end to protrude after the fiber holding device is fitted into the receptacle. The width of the central channel is sufficient to allow limited flexing of the bared fiber end in response to loads applied to its protruding part. Plugging the plug members into the socket member brings the end surfaces of the two fibers into contact inside the guide member. Flexing of the fiber in the central channel produces reaction forces to pressurize the contact. It also allows displacement of the mating plane defined by the contacting end surfaces relative to the median plane of the device.
