PROBLEM TO BE SOLVED: To realize transparently connecting single or plural wavelength signal lights transmitted from an electrical transmitting device for operating the multiple separation of information on a time axis with a photonic transport system against optical signals with different kinds of speeds without converting the signal lights into electrical signals. SOLUTION: Signal lights with each different wavelength have wavelengths, wavelength precision, optical power, the ratio of optical signal to noise, and disperse yield strength to be used by an electric transmitting device and a photonic transport system. In this case, a WDM(wavelength division multiplexing) optical interface device 12 connects the inputted light signals with each other without converting the light signals into electric signals and further into signal lights. |
