Highlights of the fiber optic.The optical fiber has many advantages. Particular vantage point late lead copper. Copper conductor to be used instead. These features have been developed continuously and improve gradually, which consists ofThe ability to send and receive information.Fiber glass rod is small, the curved bend diameter is used กันมาก 62.5 / 125 micrometers. Optical fiber size, this is a line used within. General building. When used with the light wave wavelength 850 nm. The signal more than 160 Mega เฮิรต. The length 1 kilometers. And if the wavelength, 1 300 nm. The signal has more than 500 nm. The length 1 kilometers and if reduce the length down to 100 meters. To be used with the frequency of the signal over 1 gigahertz. Therefore better UTP catalog 5 model used to signal 100 MHz.Power loss is low.Fiber optic lighting features in running through. To weaken the light is quite low. According to the standard of the fiber optic. The use of optical signal line is long, 2 000 meters. If the distance exceeds 2 000 meters, to use the repeater every 2 000 meters, loss in signal is lower than the copper tendon. At the late copper, there is no set distance of only 100 meters.If considered in terms of frequency used. The frequency response on power loss, especially in the copper conductor wire when used as the signal line, the properties of the tendon lead copper. Change when using different frequencies. Especially when the frequency of the signal transmitted in the copper conductor high. Losses would very much, but the case of optic fiber, we use signals, data transmission, it has no effect on power loss of light.Electromagnetic waves cannot be disturbed.The major problem of the signal is to see that the copper decomposition by electromagnetic waves, this problem has greatly since the interference between conductors or called cross torque Not match fit the impedance, the reflected wave, the interference from external factors called EMI these problems make the user need to keep care.But for...
