Abstract
Systems and methods for detecting laser transmission bursts in a CATV network.
Claims10
An apparatus comprising:
- a receiver having a plurality of inputs, each capable of receiving an upstream optical signal, and combining the received upstream optical signals to create a combined signal;
- a transmitter that receives the combined electrical signal and converts it to a reverse path optical signal at an output;
- and
- a controller for the transmitter that monitors each of the plurality of inputs, and activates the transmitter if an optical signal above a threshold is received at any of said plurality of inputs, where the controller monitors the sum of the signals received over all of said plurality of inputs.

- and
- a controller for the transmitter that monitors each of the plurality of inputs, and activates the transmitter if an optical signal above a threshold is received at any of said plurality of inputs, where the controller, in response to detected optical input power, controls at least one of:
- laser bias control between a low state and a high state, amplifier bias control between a low state and a high state, or RF gain,
- where the high state is activated when optical input power is detected and the low state is between zero and the high state.
