Advantages of twisted pair transmitter

Twisted pair has been in use for a long time. Twisted pair is used in many industrial control systems, places with greater interference, and long-distance transmission. The local area network we use today also uses twisted pair. The reason why twisted pair is used so widely is that it has many advantages such as strong anti-interference ability, long transmission distance, easy wiring, and low price:

1) Long transmission distance and high transmission quality. Due to the advanced processing technology adopted in the twisted-pair transceiver, the attenuation of the video signal amplitude and the attenuation difference between different frequencies by the twisted pair are excellently compensated, and the brightness and color of the original VGA image and the real-time performance are maintained , When the transmission distance reaches 300m or more, the image signal is basically without distortion.

2) Convenient wiring and high cable utilization. An unshielded twisted pair cable can transmit both high-definition image signals and high-fidelity stereo audio signals. In addition, Category 5 unshielded twisted-pair cables are widely laid in the building. Just pick one of them to transmit one signal without additional wiring. Even if it is re-wiring, Category 5 cables are easier than optical fibers and coaxial cables, which is greatly simplified. The difficulty of engineering wiring is improved, the cable utilization rate is improved, and the trouble caused by separate wiring of various signals is avoided, and the engineering cost is reduced.

3) Strong anti-interference ability. The twisted pair can effectively suppress common mode interference. Even in a strong interference environment, the twisted pair can transmit excellent image signals, and multiple twisted pairs will not interfere with each other.

4) High reliability and convenient use. Use twisted pair cables to transmit high-definition video signals, connect a dedicated transmitter at the signal source, and connect a dedicated receiver on the remote display device. This kind of twisted-pair transmission equipment is cheap and easy to use. It does not require professional knowledge and does not require much operation. It is installed once and works stably for a long time.

5) The price is cheap and it is convenient to obtain materials. Because it uses the widely used common category 5, super category 5, and category 6 unshielded twisted pairs, it is easy to buy everywhere, and the price is very cheap, which brings great convenience to engineering applications.
