The invention relates to a multi-service access digital-analog
hybrid networking all-optical distributed
system. The multi-service access digital-analog
hybrid networking all-optical distributed
system comprises a digital access unit, a digital extension unit and an analog
zoom-out unit, wherein the digital access unit and the digital extension unit are provided with
signal forwarding connections; a
signal allocation port of the digital extension unit is provided with an analog
zoom-out unit connection; the digital access unit comprises a first radio-frequency
processing unit (U1) and a first digital
processing unit (U2) which are connected to construct an uplink and a downlink; the digital extension unit comprises a second digital
processing unit (U4), a second radio-frequency processing unit (U5) and a first analog
photoelectric conversion unit (U6) which are connected to construct an uplink and a downlink; and the analog
zoom-out unit comprises a second analog
photoelectric conversion unit (U8), a third radio-frequency processing unit (U9) and an antenna unit (U10) which are connected to construct an uplink and a downlink. The multi-service access digital-analog
hybrid networking all-optical distributed
system is a novel distributed system which can support a plurality of services such as 2G services, 3G services, TDDLTE (Time Division Duplexing Long Term Evolution) services and FDDLTE (
Frequency Division Duplexing Long Term Evolution) services, and is applied to deep coverage of
wireless communication signals such as 2G signals / 3G signals / 4G signals.
