REMOTE OPTICAL COMMUNICATION SYSTEM

摘要

PROBLEM TO BE SOLVED: To prevent the span length of an optical fiber between a power amplifier and a preamplifier or the span length of an optical fiber between adjacent line amplifiers from being limited by an available optical power at the input of the span. SOLUTION: The remote optical communication system includes a transmission station 104 that sends an optical signal with a power within the range from 18 dBm to 30 dBm and a fiber whose length is 100 km to 1000 km and whose dispersion is deviated. The remote optical communication system having an optical fiber transmission line 106 that sends the optical signal and an optical reception station 108 that receives the optical signal is provided with a color dispersion compensation device 115 between the transmission line 106 and optical receivers 110, 111.
