IPC: H04B10/2563
Filed: 1997-12-11
Abstract: PROBLEM TO BE SOLVED: To attain wavelength division multiplex transmission in the optical amplification transmission system designed and installed for transmission of one wavelength. SOLUTION: Transmission optical fibers 16-1 to 16-4 and optical amplifiers 18-1 to 18-3 in an optical fiber transmission line 14 between terminal stations 10 and 12 are designed and installed for transmission of one wavelength. A wavelength converter 20 that up-shifts a wavelength of the signal light is inserted to each pre-stage of the optical compilers 18-1 to 18-3, and a wavelength converter 22 that down-shifts the wavelength of the signal light is inserted to each post-stage of the optical compilers 18-1 to 18-3. Signal lights S1-Sn are set at a wavelength band lower than a zero dispersion wavelength λ0 on the transmission optical fibers 16-1 to 16-4.  The wavelength converter 20 converts the wavelength of the signal lights S1-Sn from the transmission optical fibers 16-1 to 16-3 into a wavelength within an amplification band of the optical amplifiers 18-1 to 18-3, and the wavelength converter 22 restores the wavelength of the signal lights S1-Sn amplified by the optical amplifiers 18-1 to 18-3 to the original wavelength.

An NOx-containing gas is introduced into a minus electrode chamber, and voltage is supplied from an outer power source to the cell. In this cell, Pd electrodes treated at a high temperature are used respectively as the minus and the plus electrodes. The Pd electrode is prepared by using a paste of Pd particles diluted with an organic solvent (e.g. diethylene glycol) and by thermally treating the paste at 1,400-1,500 deg.C, preferably at 1,450 deg.C. The heat treatment of the Pd electrode at such a high temperature enhances the NOx reduction capability at 750 deg.C or lower. The Pd electrode heat-treated at a high temperature may be modified by coating with an Rh metal.

In this case, though the signals of the two networks B and C on the input side change, the change of the signal of the network O does not adapt to the signal propagation delay time from the network C to the network O and on the other hand, the change adapts to the signal propagation delay time from the network B to the network O so that the cause of the change of the signal of the network O is judged to be in the change of the signal of the network B. Then, the search of the signal propagation path is successively executed by tracing to the upstream by starting from the node which generates noncoincidence.
