ABSTRACT:
A light source (124) is used to transmit a light signal down an optical communication channel (12). In a light-reflective embodiment of the present invention, a portion of the transmitted light signal is reflected back (20) into the optical communication channel (12) to an optical receiver (126). By measuring the intensity of the reflected light, one or more operational parameters of the radio can be controlled (106). In a light-transmissive embodiment of the present invention a portion of the transmitted light signal is allowed to pass to the end of the communication channel. By measuring the intensity of the light reaching the end of the optical communicaton channel, one or more operational parameters of the radio can be controlled.
