  • Small form factor in-line switched multichannel fiber optic power monitoring apparatus
    Patent number: 6765189
    Abstract: A switched multichannel fiber optic power monitoring apparatus, includes a plurality of photodetectors, each connected to a tap of a different optical line for converting an optical signal therefrom to an electrical signal, a single switch having inputs connected to outputs of each of the photodetectors for receiving the output electrical signal from each photodetector and for switching the output electrical signals in a multiplexed manner to an output thereof as a multiplexed electrical signal, an amplifier amplifying the multiplexed electrical signal, an analog to digital converter which converts the amplified electrical signal to a digital signal, and a microprocessor which provides an output measurement signal in response to the digital signal, the microprocessor being connected to the switch to control the length of time that the switch is open for each optical line, and connected with the amplifier to control amplification thereof.
