<p>An adjustable connector for optically connecting one optical fibre (12) to another fibre (14) or a light source is disclosed. In one embodiment a base plate (16) mounting the fibre (12) is connected to another base plate (18) with a resilient member (32) between the base plates. The fibre terminates at a beam expanding or imaging lens (72). Sets of alternating first and second screws (34, 34a) axially extend from one base plate to the other such that when a test signal is transmitted to the fibre the first screws (34) can be adjusted to coarsely tilt one base plate relative to the other until approximately the desired signal strength is achieved. The second screws (34a) are then rotated to finely adjust the base plates to achieve the desired signal strength. In other embodiments adjusting screws (136,246) extend radially with respect to a cylindrical housing (104) holding the fibre so as to adjust the relative position thereof. Adjustment can also be achieved using a temporary jig (232) which can be removed and reused. With the invention insertion and tilt losses at the connector are minimized.</p> |
