Main advantages of optical fiber communication technology

The optical wave frequency is very high, and the optical fiber transmission band is very wide, so the transmission capacity is very large. Theoretically, hundreds of millions of telephone channels or tens of thousands of TV sets can be connected, and image, data, fax, control and other services can be carried out; No electromagnetic interference, good confidentiality; High temperature resistance, high pressure resistance, corrosion resistance and reliable operation; Optical fiber materials are rich in sources, which can save a large number of non-ferrous metals (such as copper and aluminum), with small diameter and light weight.
