ABSTRACT:
A method of testing the quality of a splice at a remote location made between said optical cable and a subsequent optical cable. The method includes the step of connecting a first optical switch to the optical fibers contained within said cable. The first optical switch is connected to the optical fibers at a central office from where the optical cable originates. The first optical switch is connected to test equipment at the central office, wherein the first optical switch is capable of selectively connecting the test equipment to each of the optical fibers. A second optical switch is connected to the optical fibers in the subsequent optical cable on the opposite side of the splice. Portable test equipment is optionally connected to the second optical switch at the remote location. A portable controller is also taken to the remote location. The portable controller is used to control the first optical switch at the central office, via a telecommunications link. As a result, a person splicing an optical cable at the remote location can remotely instruct that cable to be tested in an automated manner from the central office. If the test shows a poor integrity in the splice, the cable can be cut and re-spliced until a quality splice is obtained.
