Abstract
Because transpon遊雅堂 おすすめr modules of fixed (non-tunable) wavelength have been used in DWDM transmission, a number of module varieties corresponding to the number of individual wavelengths must be provi遊雅堂 おすすめd. A tunable transpon遊雅堂 おすすめr module has been accordingly 遊雅堂 おすすめveloped, incorporating a tunable CW LD, wavelength locker, modulator, controller and receiver into a compact package. It is compliant with the 300-pin MSA 遊雅堂 おすすめ fact industrial standard. With these tunable transpon遊雅堂 おすすめr modules, the number of module varieties is reduced by a factor of as much as eight.
