Multi Band Active Fiber Das

The Multi BandFiber OpticDASis designed to solve problems of weak mobile signal in the place that is far away from the Base Transceiver Station (BTS) and has fiber optic cable network underground.
The system consists of two parts: Donor Unit and Remote Unit. The Donor unit captures the BTS signal via Donor antennato BTS, then converts it into optic signal and transmits the amplified signal to the Remote Unit via fiber optic cable. The Remote unit will reconvert the optic signal into RF signal and provide the signal to the areas where network coverage is inadequate. And the mobile signal is also amplified and retransmitted to the BTS via the opposite direction.
Aluminum-alloy casing with IP65 protection has high resistance to dust, water and corrodingOmni-directional antenna can be adopted to expand more coverageTx/Rx control and alarm messages can be transmitted via one fiber optic cableAdopting WDM module to realize long-distance transmissionStable and improved signal transmission qualityOne Donor Unit can support up to 4 Remote Units to maximize utilization of fiber optic cableUSB port provides a link to a notebook for local supervision or to the built-in wireless modem to communicate with the NMS (Network Management System) that can remotely supervise repeater's working status and download operational parameters to the repeaterTo expand signal coverage or fill signal blind area where signal is weak or unavailable.Outdoor:Airports, tourism regions, golf courses, tunnels, factories, mining districts, villages, …Indoor:Hotels, exhibition centers, basements, shopping malls, offices, parking lots, …
