Title: Power spectrum monitoring and management in a wavelength division multiplexed network
Inventor: FRIGO NICHOLAS J
IPC: H04B10/08
Filed: 2002-03-06
Abstract: A power spectrum measurement system and a method monitor a power spectrum of N-channels in an M-channel wavelength division multiplexed optical communication network, where N is less than or equal to M. An add-drop node in the network drops a channel and adds a channel for transmitting data on the network. The added channel has the same wavelength as the dropped channel. The power of the added channel is controlled to minimize crosstalk. The power spectrum measurement system includes a detection circuit and a processing circuit. The detection circuit is an inexpensive, scalable circuit for detecting the power of each channel. The processing circuit is connected to the detection circuit and calculates the power of each channel based upon the power detected by the detection circuit. The processing circuit also calculates power of the added channel for minimizing crosstalk. The calculated power of the added channel is a function of the powers measured for the N channels, including but not limited to the average power of the N-channels or the powers of the channels adjacent the added channel. The calculated power is transmitted to the node adding the channel for controlling the power of the added channel.
