Title: Wavelength control method and optical communication system using the same
Inventor: KUBOTA OICHI
IPC: H04B10/2543
Filed: 1996-02-22
Abstract: PROBLEM TO BE SOLVED: To eliminate a chi-interval wavelength dependency without a new additional circuit by calculating the increased portion of a control variable corresponding to a ch-interval from a control variable value whenever the transmissive wavelength of a light transmitting means is swept. SOLUTION: A wavelength control circuit properly changes the increased portion ΔV of the control signal V corresponding to the ch-interval by the value of the control signal V so that the wavelength reliability of the ch-interval is eliminated. That is, the ΔV value is changed to be ΔV=ΔV1 when the control variable V is V1, ΔV=ΔV2 when it's V=v2 and ΔV=ΔV3 when it's V=V3 so that the corresponding ch-intervals Δλ1, Δλ2 and Δλ3 are kept to the equal value Δλch. In this case, the wavelength control circuit calculates the increased portion ΔV of the control signal corresponding to the ch-interval from the control signal by the use of a previously stored function.  The wavelength control circuit actually grasps the position relation of respective kinds of transmission wavelength through the use of the control signal V to be transmitted to a filter drive circuit and controls the transmission wavelength of a self-station and the transmitted wavelength through a wavelength variable filter.
