Fibre-optic repeater MOU (master unit)
Signal to optical conversion at the near end, up to 20 km reach
Product catalogue page 7
Near-end unit — converts the over-the-air signal into an optical signal
What this unit does in the system
The master unit is used as a set with the ROU. It offers high performance and efficiency for signal transmission of up to 20 km, providing a broad umbrella of coverage for large buildings, exhibition halls, subways, airports and large enterprise factories. One-button installation and integrated module design keep deployment simple.
