Abstract: An optical amplifier including: an amplifier having an input port and an output port, which is disposed along a main signal line of the optical amplifier; a dummy laser generation circuit having an output coupled to the main signal line and operative for inputting a dummy signal into the amplifier; a first optical detector for detecting a power level of the dummy signal into the amplifier and outputting a first power level signal; a second optical detector for detecting an amplified power level of the dummy signal output by the amplifier and outputting a second power level signal; a memory device for storing calibration data regarding the gain characteristics of the amplifier; and a gain control circuit which receives inputs from the first optical detector and second optical detector, and has an output coupled to the amplifier. The gain control circuit operates to control the gain of the amplifier based on the first power level signal, the second power level signal and the calibration data.

Abstract: A Residential Gateway (RG) for distributing video, data and telephone services to multiple devices within a residence is disclosed. The RG receives signals from a telecommunications network, converts the signals to formats compatible with the multiple devices, and transmits the appropriate signals to the appropriate devices. Wireless remote control devices (RCs) associated with remotely located televisions (TVs) transmit channel select commands to the RG as wireless signals. The wireless signals are received by Remote Antennae Packages (RAPs) coupled to the remotely located TVs. The RAPs transmit the wireless signals over coaxial cable to a Media Interface Device (MID) coupled to the RG. The MID extracts the channel select commands and forwards them to the RG. The MID is also capable of combining and splitting TV signals, and adjusting the impedance of network signals so that they can be transmitted over the coaxial cable.
