Abstract:
In a fiber-to-the-home (FTTH) system for transmitting forward and reverse optical signals, such as video, voice, and data signals, via optical fiber, the FTTH system including a plurality of home network units, the plurality of home network units including an FTTH optical receiver for receiving at least one of the video, voice, and data signals, and for providing amplified video signals to a video device via coaxial cable, the FTTH optical receiver comprising:a triplexer for distinguishing and separating the at least one of the video, voice, and data signals, and for converting the video signals to video electrical signals, wherein the video signals have a first wavelength and the voice and data signals have a second wavelength, and wherein the at least one of the voice and data signals is provided to a home network unit for further processing; a biasing network for biasing the video electrical signals; and an amplifier stage for amplifying the video electrical signals, wherein the amplifier stage comprises: a preamplifier stage for amplifying the video electrical signals: a gain control network for receiving a control signal that is indicative to an input power level at the FTTH optical receiver and for adiusting a gain level associated with the amplified video signals: and a postamplifier stage for amplifying the adjusted video signals.
