The biggest difference between digital repeater station and optical analog repeater
The main difference between digital repeater and analog repeater is in the intermediate processing and relay links. Digital processing methods, digital intermediate frequency and digital filtering technology are adopted. The analog repeater of optical fiber is an analog repeater with optical fiber relay, and the modulated light signal is transmitted in the optical fiber after the analog to intermediate frequency signal passes through the electro optical conversion.
Principle: the signal with the signal transmission optical fiber repeater received by photoelectric conversion electric light conversion to restore into optical signal, and then re issued by the near end machine close to the base station side and coverage area in the remote side of the machine is made of two parts.
