同軸電纜抗干擾能力好,傳輸數據穩定,且價格實惠,因而被廣泛使用。那麼綜合佈線時如何選用同軸電纜?
選用同軸電纜時,應考慮信號在同軸電纜內傳輸時,其受到的衰減與傳輸距離和信號本身頻率的關係。通常,信號頻率越高,衰減越大,因此同軸電纜只適合近距離傳輸圖像的信號。
但在實際工程中,若想延長同軸電纜的傳輸距離,可使用同軸放大器,透過均衡調整對不同頻率成分分別進行不同大小補償,盡可能減少接收端輸出視頻信號的失真問題。但同軸放大器不是無限制級聯,每個點到點系統中同軸放大器最多只能級聯2到3個。
因此,在監控系統中使用同軸電纜時,盡量在傳輸距離範圍限制400-500米,確保圖像質量良好。

How to*axial cable*prehensive wiring?
When selecting*axial cable, the relationship between the attenuation of the signal and the transmission distance and the frequency of the signal should*nsidered when the signal is transmitted in*axial cable. Generally, the higher the signal frequency, the greater the attenuation,*axial cables are only suitable for transmitting signals over short distances.
However, in actual engineering, if you want to extend the transmission distance of*axial cable, you can use*axial amplifier*pensate different*ponents with different sizes through equalization*nt to minimize the distortion of the output video signal at the receiving end. However, coaxial amplifiers are not cascaded*y. Each point-to-point system can only cascade up to two or*axial amplifiers.
Therefore, when*axial cables in monitoring systems, try to limit the transmission distance to 400*ters to ensure good image quality.
