1. Signal transmission method: optical fiber uses optical signal transmission, while CCTV line uses electrical signal transmission.
2. Transmission distance: The transmission distance of optical fiber is long, which can reach more than tens of kilometers, while the transmission distance of CCTV line is relatively short, usually no more than several hundred meters.
3. Wide: Optical fiber has a large bandwidth and can transmit a large amount of data, while CCTV cable has a relatively small bandwidth and is mainly used to transmit video signals.
4. Anti-interference ability: The optical fiber has strong anti-interference ability and is not affected by electromagnetic F interference and signal attenuation, while the anti-interference ability of CCTV lines is relatively weak and may be affected by the surrounding environment and electrical equipment.
5. Difficulty and cost of installation: The installation of optical fiber is more difficult and requires professional technology and equipment, while the installation of CCTV lines is relatively simple. In addition, the cost of optical fiber is relatively high, while the cost of CCTV lines is relatively low.
To sum up, optical fiber and CCTV lines have their own advantages and disadvantages, and the appropriate transmission medium should be selected according to actual needs and conditions. If you need to transmit large amounts of data or for long distances, fiber optics are a better choice; if you need simple video transmission or a lower cost solution, CCTV cables may be more suitable.
