Abstract
A wavelength debugging method of multi-channel optical module includes: determine the initial temperature of TEC, and plot the temperature-optical power curve of each channel; obtain temperature Tand Tcorresponding to upper and lower limit values of the target wavelength of each channel and the left and right security boundary temperatures T' and T′ of each channel; compare T, T, T′, T′ of each channel, when the product is qualified, record the middle two values in descending order as Tand T, respectively; compare the size of Tand Tof each channel, when the product is qualified, take the maximum value of Tof each channel as T′, and take the minimum value of Tof each channel as T′, the final setting temperature of TEC is calculated as T′=(T′+T′)/2, and the corresponding wavelength for each channel at this temperature T′ is the wavelength after debugging for each channel.
