Optical wavelength converter and optical wavelength division multiplexing communication system using the same |
摘要 |
Optical wavelength converter having a configuration whereby both RZ code and NRZ code can be handled without producing the duty deterioration in the waveform. The optical wavelength converter provided for converting an optical signal in a first optical wavelength band into an optical signal in a second optical wavelength includes an optical-to-electrical converter for converting an input optical signal into an electric signal; an electrical-to-optical converter for converting the electric signal into an optical signal; and a duty control circuit connected between the optical-to-electrical converter and the electrical-to-optical converter for controlling the duty of the electric signal having been converted by the optical-to-electrical converter according to RZ/NRZ code information.
