PURPOSE:To obtain a double window optical transmission line, by connecting a short wavelength transmitting GI type optical line and a long wavelength transmitting GI type optical line in cascade. CONSTITUTION:A short wavelength transmitting GI type optical line and a long wavelength transmitting GI type optical line are connected in cascade successively, so that an optical line C1 becomes the short wavelength transmitting GI type optical line, an optical line C2 becomes the long wavelength transmitting GI type optical line, and an optical line C3 becomes the short wavelength transmitting GI type optical line once again. In this way, a double window optical transmission line C having the excellent characteristics are obtained easily. |
