Title:
TRANSMISSION DEVICE AND TRANSMISSION METHOD
Document Type and Number:
WIPO Patent Application WO/2018/198478
Kind Code:
A1
Abstract:
[Problem] To provide a transmission device, etc., designed to expand transmission capacity while reducing component costs. [Solution] This transmission device transmits wavelength multiplexed light to a transmission line. The transmission device has a first multiplexing unit, a second multiplexing unit, a wavelength conversion unit, and a third multiplexing unit. The first multiplexing unit multiplexes light of a wavelength in a first wavelength band and outputs a first multiplexed light. The second multiplexing unit multiplexes light of a wavelength in the first wavelength band and outputs a second multiplexed light. The wavelength conversion unit converts the second multiplexed light to a wavelength in a second wavelength band different from the first wavelength band. The third multiplexing unit multiplexes the second multiplexed light that was converted to the second wavelength band and the first multiplexed light, and outputs the wavelength multiplexed light.
