Abstract
A method for an integrated status transponder using the modulation of a return laser dithering signal. This invention provides a method for transmitting an optical node monitoring signal corresponding to error detection parameters over an optical network extending from a transmission site to a receiver. A stabilizing RF signal and the optical node monitoring signal based on error detection parameters are modulated to generate an “intelligent” integrated signal. The integrated signal and the principal RF signal used for various services are sent in conjunction over an optical network to a receiving site. The integrated and principal RF signals are received from the optical network by a receiver. Start and device identification bits can be used to identify the monitoring signal and to specify a downstream destination device.
