Popis: | A primary characteristic influencing a system’s information capacity is its bandwidth. This is the number of discrete channels within a finite range of frequency. Bandwidth increases with frequency of the carrying signal. The higher the frequency used for transmission, the higher is the theoretical capacity of the system. Traditional copper pairs operate at 1 GHz, which permits transmission of more than 10, 000 voice channels, but loss of 50 dB/km limits the transmission span to |
