Abstract
The present invention discloses a frequency domain equalization method, including transmitting an optical signal transmitted over a long distance to a dispersion compensation device, and performing dispersion compensation and equalization processing on the optical signal through the dispersion compensation device. The present invention utilizes the compensation effect of a single dispersion compensation device to realize dispersion compensation and frequency equalization on the optical signal, reducing the bandwidth requirements for the devices at the emitting and receiving ends, allows the directly modulated laser to still support long-distance fiber transmission in the case of high-speed signal modulation, and greatly reduces the system cost. In addition, transmissions over different distances can be supported by changing the value for the dispersion amount, so that the distance can be adjusted flexibly according to the requirements in the data center or other application scenarios.
