Optical fibre test device

1. An optical fibre test device comprising:

a housing within a wall plug or wall box;

a first light directing device enclosed within the housing; and

a manually operable actuator coupled to the first light directing device, the manually operable actuator configured to move the first light directing device between a testing position and a non-testing position,

wherein the testing position of the first light directing device interrupts an active optical transmission path between a first optical fibre and a second optical fibre, wherein the interruption of the active optical transmission path occurs without manual handling of the first and second optical fibres, and wherein the testing position of the first light directing device enables the first light directing device to direct the light transmitted through at least one of the first and second optical fibres to an optical detector, and

wherein the non-testing position of the first light directing device re-establishes the active optical transmission path between the first and second optical fibres, and wherein the re-establishment of the active optical transmission path occurs without manual handling of the first and second optical fibres.

2. The optical fibre test device according to claim 1 , wherein the light directing device is a reflector, prism, or diffraction grating.

3. The optical fibre test device according to claim 1 , wherein the housing additionally encloses a part of the active optical transmission path between the first and second optical fibres.

4. The optical fibre test device according to claim 1 , wherein a part of the active optical transmission path between the first and second optical fibres includes free space and wherein the interruption of the active optical transmission path by the first light directing device occurs in that free space.

5. The optical fibre test device according to claim 1 , further comprising a second light directing device enclosed within the housing, the manually operable actuator additionally coupled to the second light directing device and additionally configured to move the second light directing device between the testing position and the non-testing position, and wherein the testing position places the first and second light directing devices in two different positions within the active optical transmission path and enables the first and second light directing devices to direct the active light transmitted through at least one of the first and second optical fibres to first and second optical detectors, respectively.

6. The optical fibre test device according to claim 1 , further comprising a second light directing device enclosed within the housing, the manually operable actuator additionally coupled to the second light directing device and additionally configured to move the second light directing device between the testing position and the non-testing position, wherein the testing position places the first and second light directing devices in the active optical transmission path and simultaneously enables the first light directing device to direct the active light transmitted through the first optical fibre to a first optical detector and the second light directing device to direct the active light transmitted through the second optical fibre to a second optical detector.

7. The optical fibre test device according to claim 1 , wherein the manually operable actuator is a push button or similar linear-action member.

8. The optical fibre test device according to claim 1 , which is located together with or incorporates test equipment to give a test reading at the point of actuation of the device.

9. The optical fibre test device according to claim 8 , wherein the said test equipment is attached to or incorporated in the housing or actuator of the test device.

10. The optical fibre test device according to claim 1 , wherein the wall plug or wall box are located at a customer premises.

11. A method of testing an optical fibre having an active light source, the method comprising the steps of:

positioning a light directing device, that is enclosed by a housing located within a wall plug or wall box, in an active optical transmission path that exists between a first optical fibre and a second optical fibre through manual activation of an actuator coupled to the light directing device, the positioning occurring without manual handling of the first and second optical fibres;

directing, with the light directing device, the active light being transmitted in at least one of the first and second optical fibres to an optical detector;

detecting, with the detector, the directed light to determine a quality of the directed light;

removing the light directing device from the active optical transmission path; and

re-establishing the active optical transmission path between the first and second optical fibres by repositioning the light directing device away from the optical transmission path through manual activation of the actuator.

12. The method of claim 11 , wherein the light-directing device is provided as a reflector, prism, or diffraction grating.

13. The method of claim 11 , wherein a part of the active optical transmission path includes free space and wherein positioning the light-directing device comprises positioning the light directing device in that free space.

14. The method of claim 13 , wherein the light directing device comprises at least two light directing devices and wherein the step of positioning further comprises positioning the at least two light directing devices in the active optical transmission path in at least two different positions within the optical transmission path, and wherein the step of directing further comprises directing, with each of the at least two light directing devices, the active light being transmitted in at least one of the first and second optical fibres to first and second optical detectors, respectively.

15. The method of claim 11 , wherein the wherein the wall plug or wall box are located at a customer premises.
