Description
The present invention relates between two light transmitting fibers to realize end-to-end permanent connection, in this light transmitting fiber one or both can be the assemblies of an optical cable.Usually, two fibre-optic links are permanently fixed together by fusing or refractive index matched adhesive (index-matching adbesive).
Realizing that these two kinds connect in the fibre-optic methods, before two permanent linking together of light transmitting fiber, need to guarantee two light transmitting fiber fuses in the axial direction in line so that best from a light transmitting fiber to the fibre-optic light transmission of another root.Under the situation of monotype photoconduction fiber, the diameter of light transmitting fiber fuse is less than its overall diameter, and at this moment, two light transmitting fibers axially are crucial especially in line.
At present, two kinds of axial straight methods of two light transmitting fibers that obtain the best are most popular.In the first method; light is injected into wherein fibre-optic end away from the junction; perhaps be injected into light transmitting fiber near the junction; (isolate overcoat is softer polymeric material overcoat to isolation overcoat on it; it is topped protects it to avoid mechanical damage on fibre-optic fluctuation surface, reduces little refraction loss; make fiber and keep this shape with less radius bend, this is that additive method institute is inaccessiable.) on the part peelled off, the total amount of the light that flows into another root light transmitting fiber covering of light transmitting fiber link place is monitored continuously.Fibre-optic one or two relative to laterally moving, are reached minimum until above-mentioned monitored light, this just represent light transmitting fiber rightly retainer shaft connect then in line.In the second method, light be injected into wherein one fibre-optic away from the junction an end or be injected into light transmitting fiber near the junction, on the part that isolation overcoat on it has been peelled off, fibre-optic at this away from an end of junction or in of continuous the monitoring in position of this light transmitting fiber near the junction being transferred to the fibre-optic light of another root.Fibre-optic one or two relative to laterally moving, until fibre-optic away from end or above-mentionedly draw the light that shows near the position, junction and reach maximum from another root, this just represent light transmitting fiber rightly retainer shaft connect then in line.
In order to make the required operating personnel of this method of operation minimum, to it would be desirable light is injected into the place of first light transmitting fiber near the junction.Under first kind of situation, the light that spreads out from light transmitting fiber connection termination is by continuous monitoring; Under second kind of situation, from another root light transmitting fiber near the light of the local outgoing of junction by continuous monitoring.
If light transmitting fiber is peelled off near the isolation overcoat in place, junction, it is can be not inconvenient that light is incided this place, yet, we have found that, do not peel off if isolate overcoat, so, it is difficult inciding light near going in the light transmitting fiber fuse of junction fully.This difficulty is under the smaller monotype photoconduction fiber situation of fuse diameter, and is more obvious.
