GSM900MHz Fiber Optical Repeater

•  Monitoring software can be upgraded locally or remotely.
•  Wide dynamic range, low power consumption and noise figure. Protection from over voltage, over current and over temperature
•  High isolation from uplink to downlink to improve high stability.
•  High reliability and MTBF≥100,000 hours
•  Perfect remote and local network monitoring function.
•  Avoid interference from co-frequency
•  Enlarge the coverage area with omni directional antenna
•  Extend the signal distance of base station
•  Backup batteries
•  Main module self-test and auto alarm.
•  Door open alarm
•  ALC(auto level control).


To expand signal coverage of signal blind areas where signal is weak or unavailable.  Outdoor:  Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.  Indoor:  Hotels, Exhibition Centers, Basements, Shopping Malls, Offices, Parking Lots etc
