Digital Fiber Optical Repeater is an integrated solution for coverage enhancement. This system consists of Digital Access Unit (DAU) and Digital Remote Unit (DRU). With digitized IF and high IP3 linearization technology, this system largely lowers the requirement of isolation between antennas. Support all kinds of connection methods between DAU and DRU. The DRU’s fully weatherized enclosure with the built-in AC power surge arrestor allows product installation at any outdoor environment and powered by exposed power lines. This solution provides effective coverage enhancement. It is suitable for applications such as citywide enhancement, highway and canyons, campus, underground tunnels, airports and convention centers, etc.
Digital Repeater is an ideal solution for urban area coverage and is optimal for both indoor and outdoor applications. The Comba AFC technology is deployed in this repeater to reduce the antenna isolation requirement. UNC technology is also available to reduce uplink interference for dense urban area deployment. (i.e., multiple units in same donor sector).
