摘要： An optical connector (2) includes a housing (4) having a through bore (10) therethrough terminating at an end face (8) of the housing (4). A short section of fibre (12) is inserted into an end of the connector housing (4) into the through bore (10) with a portion protruding beyond the end face (8). The protruding section is ground to effect a smooth finish. A gel is inserted within the through bore (10) adjacent and in abutment with the unfinished end (13) of the short fibre (12). A fibre (24) to be spliced can be inserted within the connector (2) into the through bore (10) and into optical abutment with the gel (20) such that the gel conforms to the two unfinished surfaces (13, 25) of the fibres (12, 24). The end face (8) of the connector (2) can be brought into optical abutment with a similar connector (2) to effect optical continuity between two similar fibres (12, 24). The fibre (13, 25) comprises a core material (14) surrounded by a thin cladding material (16) where the cladding material (16) has an index of refraction less than the index of the core material (14). Furthermore, the index of refraction of the inner surface (6) of the through bore (10) has an index of refraction equal to or less than the index of refraction of the cladding material (16).

摘要： A method of breaking an optical fiber comprises the steps of surrounding the fiber with elastomeric material in the region of the desired break location and then compressing the elastomeric material towards the axis of the fiber. When the material is compressed, it grips the fiber so that the fiber and the material cannot move relative to each other. Compression of the material also results in elongation of the material so that the fiber is placed in tension and fractures at the desired break point. An apparatus for carrying out the processes is also disclosed.

摘要： A switch for optical fibers includes two identical housing halves for retaining the optical fibers in a substantially fixed position. The fibers are retained within the housing halves forming two pairs of opposed optical fibers. An intermediate fiber is provided between the opposed fibers, and each end of the intermediate fiber is moveable into alignment with one of two fibers to form four switching positions. The intermediate optical fiber is externally plated with a metallic coating which provides a resiliency to the fiber, allowing the fiber to provide its own spring retention within an associated alignment groove. A switching plate is also provided for each free end of the intermediate fiber for switching movement of the free ends into optical alignment with the free ends of the optical fibers. Transverse movement also axially moves the optically aligned fiber out of an abutting relationship with the free end of the intermediate fiber to maintain the surface finish on the ends of the optical fibers. The switch can also be made in the form of an electromagnetic switch where end portions of optical fibers having ferromagnetic metal coatings of constant thickness are secured together in pairs in an alignment channel adjacent a solenoid. The pair of fiber end portions are fixed adjacent one channel sidewall and the pair are movable by activation of the solenoid from a position in which they are inherently spring-biased against the opposite sidewall with only fibers and in optical alignment to a position in which they abut sidewall bringing fibers and, respectively, into alignment.
