ABSTRACT:
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).
