Where the continuous use and operation of cell phone jammer

 Where the continuous use and operation of cell phone jammer for a long time is needed.
The principle of optical fiber transmission ILD issued by the light emitting diode LED or an injection laser diode optical signal transmitted along the optical media, PIN or APD photodiode as the

detector to the received signal at the other end. Optical carrier modulation Amplitude Shift Keying, also known as brightness modulation. The typical approach is to represent the two binary digits

in the given frequency of light appear and disappear. The light emitting diode LED and injection laser diode ILD signal can be used this approach modulation PIN and ILD detector in direct response

to the brightness modulation. Power amplifier - the optical amplifier placed in the optical transmitter side in order to enhance the power of light into the fiber. The life time of cell phone

jammer is long to be used outside.
So that the optical power of the entire wiring system is improved. Line relay to enlarge - the large buildings or floor distance, from the relay amplification, to mention a high optical power.

Preamp - after the receiving end of the photoelectric detector micro-signal amplification in order to improve reception. 2.2.2 optical transmission distortion of light in optical fibers will

produce some distortion, the distortion for the following reasons: (1) in the optical fiber transmission systems, semiconductor laser, electrical / optical conversion characteristics nonlinear

changes in the output optical signal and the excitation current inconsistent and lead to a distortion, it is called modulation distortion. Modulation index M values do not allow too large. cell

phone jammer has no time limitation.
Select high-performance, pre-distortion processing technology of the optical transmitter is necessary, pre-distortion processing technology is the use of man-made design to produce pre-distortion

to improve modulation linearity. To eliminate and reduce the optical fiber transmission system, the purpose of CSO and CTB. (2) optical transmission systems, to drive the RF amplifier and the

receiver RF amplifier to produce a very small chance of distortion, linear PIN photodiode signal level is not too high, the slight distortion from time to count, it's the main reason distortion

from the modulation characteristics of semiconductor lasers and fiber dispersion. The laser light intensity modulation, the wavelength of the light changes, the additional frequency modulation

signal frequency broadening, chirp effect appears mainly for the CSO distortion.
