IPC: H04B10/2525
Filed: 1997-08-20
Abstract: PROBLEM TO BE SOLVED: To control dispersion of wavelength in a channel without interrupting the system operation by supervising and controlling wavelength dispersion in the channel through which an optical signal essentially not including a clock component such as a return to zero RZ signal and an optical time division multiplex OTDM signal is transmitted. SOLUTION: In the case a bit rate of an optical signal is B b/s, a band pass filter 42 extracts a B Hz component from a base band signal obtained by a receiver side light receiving device 40 and a variable dispersion compensation device 34 is controlled so as to minimize the intensity of the above signal. For the control of the system operation, a low frequency signal from an oscillator 52 is superimposed on a control signal of the variable dispersion compensation device 43. A band pass filter 60 extracts a low frequency component from the detection output of the B Hz component and a phase of the low frequency is compared with a phase of the low frequency signal from the oscillator 52, thus the dispersion compensation amount is automatically controlled depending on the result.
