Abstract
A connector for monomode optical fibres comprises two connectable housings in each of which is secured the end of an optical fibre which is substantially coaxially aligned with at least two light displacement means which produce a light beam with a predetermined form from light transmitted along the optical fibre. The light beams from the two housings are complementary so that a light beam from either housing is focussed onto the end of the optical fibre in the other housing when the two housings are connected. The light displacement means may be convex or concave lenses, SELFOC (Registered Trade Mark) lenses, prisms or combinations of these. The light beam from each housing is preferably parallel but one can be divergent and the other convergent. They may also both be divergent with an additional lens between the housings.
Claims7
An optical connector arranged to be coupled with a complementary connector to form an optical connection between optical fibres, said connector including:
- support means for supporting an end of a first of said optical fibres;
- an optical axis, said support mean supporting said end of said first optical fibre nominally on said optical axis;
- a first light displacement means mounted on said optical axis, said first light displacement means having a first light displacement power;
- a second light displacement means mounted on said optical axis, said second light displacement means having a second light displacement power;
- mounting means for said second light displacement means, said mounting means permitting adjustment of said second light displacement means orthogonally of said optical axis;
- and joining means permitting the optical connector to be coupled to said complementary connector to form an optical connection between an optical fibre supported thereby and said first of said optical fibres.
