1. In a wavelength Division multiplexed optical system, the combination comprising:

  • a first optical node including a transponder having a test signal generator for generating a test signal, and a monitoring circuit for monitoring a received test signal;

    a second optical node including a transponder having a test signal generator for generating a test signal, and a monitoring circuit for monitoring a received test signal;

    a light path interconnecting said first and second optical nodes, wherein said light path is tested by the monitoring circuit of the transponder of said second optical node by monitoring a quality of the test pattern generated by the test signal generator of the transponder of said first optical node.
