Title: Optical transmitter, optical communication system using the same and wavelength control method
Inventor: KUBOTA OICHI
IPC: H04J1/00
Filed: 1997-07-01
Abstract: PROBLEM TO BE SOLVED: To flexibly transmit a signal in accordance with the wavelength interval of output light by changing and controlling a transmission signal in accordance with detected wavelength interval so that it can be practically received. SOLUTION: While a communication node holes stationary wavelength interval Δλ0 with a channel ch1 as a channel ch2, it sends data at a transmission speed Rnormal. When adjacent wavelength interval of the channel ch2 is rapidly reduced and the node detects that wavelength interval of both channel is less than a prescribed change wavelength interval Δλ1, it sends a signal notifying the change of a transmission speed in advance to a communication node of a receiving end. After the lapse of a prescribed time, it changes the transmission speed from a normal speed Rnormal to Rslow.  After that, when it detects that wavelength interval is increased and that it is Δλ1 or more, it sends a change signal to the communication node on the receiving end and changes the transmission speed from Rslow to the normal transmission speed Rnormal after change preparation time passes.
