FM broadcasting digital relay station

  Product introduction:
FM broadcasting digital relay station mainly solves the problem that the optical fiber link is too long, resulting in excessive light loss, and the near and far end optical link of repeater cannot communicate
This equipment is added in the middle of its optical link for optical path transfer, so as to ensure the normal communication and operation of the near and far end of repeater

Product features:
1
High integration, small volume and light weight
2
Full digital mode, simple debugging
3
After power failure and restart, it can directly enter the state before power failure without setting
4
The maximum relay transmission distance can reach 50km
5
The whole machine has large dynamic range and low power consumption
Scope of application: it is mainly used to solve some enclosed spaces, such as tunnels, basements, underground garages, underground traffic hubs and other areas that cannot be covered by FM broadcasting signals
