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.
2) Î½ is the Greek letter nu. It is NOT the letter v, it is the Greek letter nu. It stands for the frequency of the light wave. Frequency is defined as the number of wave cycles passing a fixed reference point in one second. When studying light, the unit for frequency is called the Hertz (its symbol is Hz). One Hertz is when one complete cycle passes the fixed point in one second, so a million Hz is when a million cycles pass the fixed point in one second. There is an important point to make about the unit on Hz.
