Optical network because of the need to transform optical signals for the computer signals, so on the connector is more complicated, besides having connected the various types of optical fiber connector (such as SMA, FC, SC, ST fiber connectors), need special equipment, including fiber optic repeater, in charge of the light signal into electrical signal computer, and to send light signals to other network devices.
Optical fiber is a promising network transmission medium. However, due to the current high price, it is not necessary for small and medium sized office lans to choose it. Current applications of fiber optics are used as backbone lines in large lans. But as costs fall, in the near future, fibre will reach buildings, homes and even the desktop, giving us a new high-speed experience.
