Apparatus for transmitting/receiving variable-wavelength optical signal

摘要

There is provided an optical transceiver apparatus including an optical transmitter configured to transmit light of variable wavelength, an optical receiver configured to receive light generated from an opposite light source, and a controller configured to perform initialization to a wavelength corresponding to when an intensity of light received by the optical receiver is greater than or equal to a reference power, while varying the wavelength of light output by the optical transmitter.

1. An optical transceiver apparatus, comprising:
an optical transmitter configured to transmit first light, a wavelength of the first light being variable; an optical receiver configured to receive second light generated by and transmitted from an opposite-side light source; and a controller configured to initialize the wavelength of the first light by
detecting a first intensity of the second light received by the optical receiver at a first time when the received second light has a power greater than a reference power,detecting a second intensity of the second light received by the optical receiver at a second time when the received second light has a power smaller than the reference power,determining an initialization value of the optical transmitter, the initialization value being a middle value of two current values of the optical transmitter respectively at the first and second times, andinitializing the wavelength of the first light output by the optical transmitter using the initialization value.
