Patent number: 7548696Abstract: A fiber-to-the-home (FTTH) system transmits forward and reverse optical signals, such as video, voice, and data signals, via optical fiber, and includes a plurality of home network units. The home network units include an optical receiver for receiving at least one of the video, voice, and data signals. Included is a plurality of gain stages that are distributed throughout the optical receiver. The gain stages include a preamplifier stage, two interstage amplifiers, and a postamplifier stage. Two gain control circuits automatically adjust the gain of the video signal based upon the input power level to the FTTH optical receiver. Additionally, a tilt network performs level compensation for externally located coaxial cable. A signal is then provided to a device located within a home via the coaxial cable at the proper RF level having low noise signals.Type: GrantFiled: February 15, 2006Date of Patent: June 16, 2009Assignee: Scientific-Atlanta, Inc.Inventor: Robert R.
