Optical transmission device |
摘要 |
An optical transceiver includes an optical transmitter. The optical transmitter varies the wavelength of its output beam in accordance with the setting of a digital to analog converter. Two split beams emerging respectively from beam splitters are introduced into a photodetector and a wavelength filter, respectively. A quotient is calculated by dividing the digital value output from an analog to digital converter (ADC) by the digital value output from another ADC. A memory address m is then determined based on this quotient without making any calculation for compensating for the imperfect characteristics of the wavelength filter. A wavelength notification value is then selected from a wavelength notification table based on the determined memory address m, and sent to the system host.
