ABSTRACT:
Apparatus and method for equalizing a multiplicity of amplifier optical output signals comprised of a combined broadcast optical signal and a narrowcast optical signal having different bands of wavelengths of light by adjusting the power output level of at least one the signals in response to an amplified sample of the signal. A light switch or attenuator and a sensor for determining whether a transmission fiber is in place is connected to each of the multiplicity of optical output signals to allow the optical output signals to be turned on and off for maintenance and repair.
