PX-WNX with unique design, with high transmission signal-to-noise ratio, and comprehensive application of common mode rejection and shielding shell technology to enhance the anti-interference ability, which can effectively suppress high frequency, medium frequency and low frequency noise interference. The engineering of the common elevator monitoring interference, frequency conversion motor, switch power supply high frequency interference, 50/100Hz power frequency interference, medium and short wave radio radiation interference, is particularly obvious effect, image transmission quality will be significantly improved, even completely eliminate the disturbance. At the same time with lightning protection function. Particularly suitable for strong interference with the outdoor environment.
Due to the magnetic coupling, the signal source and receiving end potential difference caused by high and low frequency interference, mostly because of the loop produced, PX-WNX except with the above anti-interference characteristics, the optical isolation completely every Jedi loop, greatly inhibited loop caused by various kinds of interference.
PX-WNX also has the function of video signal equalization, which can compensate the attenuation and frequency distortion of video transmission based on the cable transmission characteristics, and greatly extend the transmission distance (up to 1000 meters).
