Adaptor for an optical connector

1 . An adaptor for an optical connector, the optical connector defining first and second optical connector channels, wherein the adaptor comprises a first part to couple to the optical connector and a second part comprising a connector portion for coupling to an optical device, wherein the connector portion comprises a first and a second waveguides configured to optically couple the first and second optical connector channels to the optical device, wherein the first and second parts are movably coupled to one another, and wherein the first part is movable relative to the second part between first and second configurations to selectively adjust a polarity of the first and a second waveguides of the connector portion relative to the first and second optical connector channel of the optical connector.

2 . The adaptor of claim 1 , wherein the adaptor comprises a locating configuration, in which the first part is restricted from moving between the first and second configurations; and an adjustment configuration, in which the first part is movable relative to the second part between the first and second configurations.

3 . The adaptor of claim 2 , wherein in the locating configuration, the first part is optically coupled to the second part; and in the adjustment configuration, the first part is optically decoupled from the second part.

4 . The adaptor of claim 2 - or 3 , wherein the first part is movable relative to the second part in a first direction between the locating configuration and the adjustment configuration; and wherein the first part is movable relative to the second part in a second direction between the first and second configurations.

5 . The adaptor of claim 4 , wherein the first part is biased towards the locating configuration.

6 . The adaptor of claim 1 , wherein the adaptor comprises one or more locating features for locating the first part in the first and second positions relative to the second part.

7 . The adaptor of claim 6 , wherein the locating features comprise one or more protrusions protruding from one of the first and second parts and two or more recesses formed in the other of the first and second parts for receiving the one or more protrusions when the adaptor is in the first and second configurations, in order to prevent the first part moving relative to the second part between the first and second configurations.

8 . The adaptor of claim 1 , wherein the first part is rotatable relative to the second part about a pivot axis between the first and second configurations.

9 . The adaptor of claim 8 , wherein the adaptor comprises a pivot pin defining the pivot axis, wherein the first part is rotatable about the pivot pin relative to the second part between the first and second configurations.

10 . The adaptor of claim 2 ,

wherein the first part is rotatable relative to the second part about a pivot axis between the first and second configurations; and

wherein the first part is linearly movable in a direction with a component parallel with the pivot axis between the locating configuration and the adjustment configuration.

11 . The adaptor of claim 9 , wherein the first part and/or the second part is linearly movable along the pivot pin between the locating configuration and the adjustment configuration.

12 . The adaptor of claim 1 , wherein the second part comprises first and second fibre optic ferrules respectively defining first and second optical channels of the adaptor.

13 . The adaptor of claim 1 , wherein the first part comprises first and second intermediate fibre optic ferrules for optically coupling to the first and second optical connector channels respectively.

14 . The adaptor of claim 12 , wherein when the adaptor is in the first configuration, the first fibre optic ferrule is optically coupled to the first optical connector channel and the second fibre optic ferrule is optically coupled to the second optical connector channel, and when the adaptor is in the second configuration, the first fibre optic ferrule is optically coupled to the second optical connector channel and the second fibre optic ferrule is optically coupled to the first optical connector channel.

15 . The adaptor of claim 1 , wherein the first part is configured to couple to the optical connector, such that portions of the optical fibres carried by the optical connector extend beyond the first part to be received within the second part.

16 . The adaptor of claim 1 , wherein a shape of the connector portion corresponds to a shape of the optical connector.

17 . A method of adjusting the polarity of an optical connector, the optical connector defining first and second optical channels, wherein the method comprises:

coupling the optical connector to an adaptor, wherein the adaptor comprises a first part to couple to the optical connector and a second part comprising a connector portion for coupling to an optical device, wherein the connector portion comprises a first and a second waveguides configured to optically couple the first and second optical connector channels to the optical device, wherein the first and second parts are movably coupled to one another, and wherein the first part is movable relative to the second part between first and second configurations to selectively adjust a polarity of the first and a second fibre optic ferrule waveguides of the connector portion relative to the first and second optical connector channel of the optical connector; and

adjusting the position of the first part of the adaptor relative to the second part to thereby adjust the polarity of the connector portion.

18 . The method of claim 17 , wherein the adjusting the configuration of the adaptor comprises: displacing the first part relative to the second part in order to disengage one or more locating features locating the position of the first part relative to the second part; and displacing the first part between the first and second positions.
