| 摘要 |
An improved method is provided for channel tagging optical data signals in an optical communication system. The method includes: generating an optical carrier having a given wavelength from an optical signal source; modulating the frequency of the optical carrier at the optical signal source, thereby embedding a tag in the optical carrier; modulating the tagged optical carrier with a data signal to form an optical data signal; and transmitting the optical data signal in the optical communication system. The method may further comprise detecting the embedded signal tag using an FM demodulator.
