Optical transmission device and optical transmission method

摘要

There is provided an optical transmission device including: a packet disassembler configured to disassemble a packet into a plurality of signals having a different wavelength; an amplifier configured to amplify, for each of the wavelength, each signal into which the packet is disassembled by the packet disassembler, based on a correction value set for each wavelength; and a multiplexer configured to multiplex the respective signals amplified by the amplifier so as to transmit a packet generated by multiplexing the respective signals.

1. An optical transmission device comprising:
a packet disassembler configured to disassemble a packet into a plurality of optical signals having different wavelengths; a controller configured to compare a route number of the disassembled packet with stored route numbers in a correction value table; an amplifier configured to amplify, based on the comparison, the plurality of optical signals having different wavelengths, according to a correction value set according to one of a route number of the disassembled packet and each of the different wavelengths and an initial value to correct wavelength dependence in a WDM network by transmitting the plurality of optical signals in advance at an optical output level to compensate for a tilt amount of each of the different wavelengths at a destination of the plurality of optical signals; and a multiplexer configured to multiplex the amplified plurality of optical signals having different wavelengths and to transmit a packet generated by the multiplexing.
