Product Description

  • “SB Digital Fiber Optic Repeater” is a medium-sized mobile communication repeater specially designed for the high density low rise housing area. Main Hub Unit (MHU) received clear signals from the Base station, and those signals are distributed via optical fiber and coaxial cables to shadow areas. Those signals are sent to a Remote Optic Unit (ROU) and Remote RF Unit (RRU), located in the shadow area, and transmits the signals to mobile device by service antenna.

  • Our Fiber & Coaxial Repeater is the advanced system with full digital technology. Compared to the Analog Fiber, our system allows strong and consistent signals regardless of long distance from the signal source with the compact size which is optimized to install on the pole. Our digital technology regenerates the weakened signal into BTS quality without any degradation.

  • Multiple small cell solution with competitive price, RRU, will help you to cut down your CAPEX of mobile network. If you locate RRU nearby ROU, it will cover the shading area effectively with low cost than fiber. However, the distance is limited lower than 100m due to high signal loss by the coaxial cable.
