The features of the digital fiber optic repeater station
- The digital fiber optic repeater station supports chain topology, star topology, and a combination of star and chain topologies.
- The Master unit and remote unit support a one-to-many star topology, where one Master unit can be connected to at least 4 remote units in a star configuration.
- One remote unit supports chain connections of at least 6 additional remote units.
- Optical fiber is used for transmission between the RF Master unit and the remote unit, with a maximum transmission distance of over 10 km.
- Supports multi-operator co-building and sharing.
