Abstract
An improved optical switch allows for the testing, calibration and monitoring of optical switch points in an optical switching matrix. A test column and a test row of additional switch elements and optical paths enable the improved optical switch to provide testing, calibration and monitoring of each optical switch point in the optical switch matrix using a test input source and a test output receiver. The improved optical switch may also be used to test for the presence of light at any input and to inject a test signal into the matrix in order to test for the presence and quality of light at any output.
