The FPT-5000 is a Fiber Optic cellular repeater for CDMA, GSM, and AMPs. When utilized with our RPT-9000 cellular extender, the FPT-5000 allows the antenna from the RPT-9000 to be extended over fiber optic cable, up to 50 km/30 miles away. This allows the RPT-9000 to operate when obstacles like hills, mountains, and large buildings block the line of sight. The FPT-5000 can be utilized with other 3rd party equipment which has an RF-based signal. The FPT-5000 comes as a complete link set with two units for each side of the fiber optic cable.
