Patent ID: 7386231

Claim:
A method for testing network data signals in an optical wavelength division multiplexing network, comprising: providing an optical wavelength division multiplexing function; providing a network analysis function; utilizing the optical wavelength division multiplexing function to produce a single wavelength carrier signal; passing the single wavelength carrier signal to the network analysis function; using the network analysis function to perform at least network signal level analysis on the single wavelength carrier signal; incrementing the optical wavelength division multiplexing function through a plurality of the single wavelength carrier signals; and performing out-of-service bit error rate testing on an optical wavelength division multiplexing network by: utilizing the network analysis function on to generate a test signal; utilizing the optical wavelength division multiplexing function to convert the test signal to the single wavelength carrier signal; passing the test signal on the single wavelength carrier signal through the optical wavelength division multiplexing network; receiving the test signal from the optical wavelength division multiplexing network into the network analysis function; and analyzing the received test signal to determine the condition of the optical wavelength division multiplexing network.
