Abstract

An optical connector includes a first attachment area for receiving and permanently attaching to an optical waveguide. A light coupling unit is disposed and configured to move translationally and not rotationally within the housing of the connector. The light coupling unit includes a second attachment area for receiving and permanently attaching to an optical waveguide received and permanently attached at the first attachment area. The light coupling unit also includes light redirecting surface. The light redirecting surface is configured such that when an optical waveguide is received and permanently attached at the first and second attachment areas, the light redirecting surface receives and redirects light from the optical waveguide. The optical waveguide limits, but does not prevent, a movement of the light coupling unit within the housing.

Claims (7)

1. An optical connector configured to mate with an optical mating connector along a mating direction and comprising a housing comprising spaced apart first and second attachment areas for receiving and permanently attaching to an optical waveguide, such that during mating with the mating connector, the first attachment area moves within and relative to the housing in a first direction substantially orthogonal to the mating direction and the second attachment area moves within and relative to the housing in a different second direction.

2. The optical connector of claim 1 , wherein the second direction is substantially orthogonal to the first direction.

3. The optical connector of claim 1 , wherein the second direction is substantially parallel to the mating direction.

4. The optical connector of claim 1 further comprising a light coupling unit disposed therein and comprising the second attachment area, the light coupling unit configured to receive light from an optical waveguide received and permanently attached to the first and second attachments areas and redirect the received light.

5. The optical connector of claim 1 , wherein, when the optical connector is unmated, the optical waveguide is substantially unbent between the first attachment area and the second attachment area, and, when the optical connector is mated to the optical mating connector, the optical waveguide bends between the first attachment area and the second attachment area.

6. The optical connector of claim 1 , wherein, when the optical connector is unmated, the optical waveguide is bent between the first attachment area and the second attachment area by a first amount, and, when the optical connector is mated to the optical mating connector, the optical waveguide between the first attachment area and the second attachment area is bent by a second amount, wherein the second amount is greater than the first amount.

7. The optical connector of claim 4 , wherein the housing includes at least one guide arranged to limit the light coupling unit from rotating within the housing.
