Abstract
A method for remotely tuning a transmitter in an optical communication system includes sending a control signal from a first location to a temperature controller at a second location and setting a first transmitter at the second location to a first temperature by the temperature controller in response to the control signal. The emission spectrum of the first transmitter can reach maximum power at or in the vicinity of a predetermined wavelength.
