Optical drop device, optical drop method, and optical add device |
摘要 |
An optical drop device includes: a clock extractor configured to extract a clock signal from a multi-channel optical signal that includes a plurality of optical signals having different optical frequencies; a pulse generator configured to generate a pulse signal that is synchronized with the clock signal; an optical inverse Fourier transform unit configured to transform the multi-channel optical signal into a time division multiplexing optical signal by using an inverse Fourier transform; and an optical switch configured to drop an optical signal that exists in a time slot to which the pulse signal is applied, from the time division multiplexing optical signal. |
