A wave asked questions with the has two components: the amplitude and the frequency ONE introduction of the TrueNet™ (frequency can also be called wavelength). The amplitude is Structured Cabling System is, the “height” of the wave. The frequency, or wavelength, is “Why do you only offer patch cords in certain lengths?” the number of peaks in a given timeframe (see Figure 2). Specifically, those lengths are 4, 7, 10 and 15 feet. And the simple answer is: certain patch cord lengths cause unacceptable signal reflection and distortion to Ethernet signals, leading to errors and poor network throughput. Factory-terminated 4, 7, 10 and 15 foot Amplitude TrueNet cords prevent this distortion, preserving the integrity of 10/100Base-T Ethernet signals. Wavelength What is an Ethernet signal? Figure 2: Sine wave. The explanation of what an Ethernet signal is, is rather complex. In fact, in order to begin, it is first important to The illustration below (Figure 3) shows four different understand the composition of an Ethernet signal. sine waves, each with the same amplitude, but having varying frequencies. An Ethernet signal is designed to mimic the binary language of computers (ones and zeros), by creating a signal which can be sent over a distance. One of the binary signaling methods that is easiest to understand is Morse code, where a quick “dot” is one and a long “dash” is zero. Ethernet uses electrical impulses to create a signaling method which also can be interpreted as zeros or ones. The basic idea is to create a square wave, seen below (Figure 1), where the instantaneous changes up and down are used in indicate the one or zero. Using electrons to create a signal that looks like a square wave is somewhat tricky, but here is the basic idea: Figure 3: Sine waves of varying frequencies. In order to create a .
