TAILIEUCHUNG - Ethernet Signal PreservationIn Factory-Terminated Patch Cords for Local Area Networks

An electrical impulse takes the shape of a sine wave. A wave has two components: the amplitude and the frequency (frequency can also be called wavelength). The amplitude is the “height” of the wave. The frequency, or wavelength, is the number of peaks in a given timeframe (see Figure 2). 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 TrueNet cords prevent this distortion, preserving the integrity of 10/100Base-T Ethernet signals | O K RO NE. Ethernet Signal Preservation In Factory-Terminated Patch Cords for Local Area Networks. NE of the most commonly asked questions with the introduction of the TrueNet Structured Cabling System is Why do you only offer patch cords in certain lengths Specifically those lengths are 4 7 10 and 15 feet. An electrical impulse takes the shape of a sine wave. A wave has two components the amplitude and the frequency frequency can also be called wavelength . The amplitude is the height of the wave. The frequency or wavelength is the number of peaks in a given timeframe see Figure 2 . 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 TrueNet cords prevent this distortion preserving the integrity of 10 100Base-T Ethernet signals. What is an Ethernet signal The explanation of what an Ethernet signal is is rather complex. In fact in order to begin it is first important to understand the composition of an Ethernet signal. 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 1 The square wave of an Ethernet signal. The illustration below Figure 3 shows four different sine waves each with the same amplitude but having varying frequencies. In order to create a signal that looks like a square wave you need to create a signal which .
