ABSTRACT:
Apparatus and methods are provided for controlling a light emission from an end of an optical fiber by utilizing a cover that blocks the light emission at the fiber end, a detector situated between the fiber end and the cover that detects the blocked emission, and a signaling device, such as an LED, associated with the detector that illuminates in response to the detection of the blocked emission. The apparatus and methods may further provide for the filtering out of light from the emission that is not used for communications. The apparatus and methods may also provide for the attenuation of the power of the emission before the emission reaches the detector.
