Abstract
Disclosed herein is an optical router based on dynamic wavelength assignment, for receiving data signals and an aggregate control signal from servers, and comprising a modulation module and a wavelength selection module, which comprises a multi-wavelength light source for generating an input carrier having wavelengths, and a carrier processing unit for separating the input carrier into carriers and for guiding the carriers to the modulating units based on the aggregate control signal. The modulation module comprises an optical coupler and modulating units in one-to-one correspondence with the servers. Each modulating unit is adapted for receiving the data signal from the corresponding server and for modulating the received carrier into an optical signal based on the data signal. The optical coupler is adapted for aggregating the optical signals into an aggregate optical signal.
