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.
