Abstract

Circuit design was made in case of applying an Er{sup 3+}-doped fiber amplifier (EDFA) to the conventional one-wavelength optical communication system and four-wavelength division multiplexing optical communication system with two in-line amplifiers. Circuit-designed to use two EDFA`s for amplifying an optical signal with a wavelength of 1540nm, the one-wavelength optical communication system experimentally demonstrated that the circuit could be formed to the maximum length of 180km. In the remote pumping through the signal transmission line used as a pumped optical supply line, the electric source is not necessary at the amplification point, so that the EDFA can be utilized under a good condition, if the pumped optical output is sufficiently high. The wavelength to pump the EDFA is 0.98{mu}m and 1.48{mu}m. Circuit-designed to multiplex wavelengths around 1555nm, the four-wavelength division multiplexing optical communication system with two in-line amplifiers gives the smallest difference in output among wavelengths on condition that the wavelength is set to equalize the amplified wavelength output at both transmission and reception points at the required input level. Mutual relation was elucidated among the in-line input level, working wavelength band and transmission distance. 8 refs., 41 figs.
