Optical Ethernet overview What if all corporations could connect buildings thousands of miles apart as easily as if they were just connecting two floors of the same building? What if every access and metro network was as simple, fast, and reliable as a Local Area Network (LAN)? What if Metro Area Networks (MANs) and Wide Area Networks (WANs), with their
The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation. Frequency is the number of occurrences of a repeating event per unit time. According to Wikipedia, The sine wave or sinusoid is a mathematical function that describes a smooth repetitive oscillation.
Sine waves can be measured too. The shape of a sine wave is given by its amplitude, phase, wavelength and frequency. The speed that the sine wave moves can be measured. The amplitude and wavelength of the sine wave is shown in the picture. The highest point on a wave is called the peak. The lowest point is called the trough. The peak of a wave and the trough of a wave are always twice the wave's amplitude apart from each other. The part of the wave half way in between the peak and the trough is called the baseline. Complicated wave forms (like the sound waves of music) can be made by adding up sine waves of different frequencies.
