RF Laser Repeater
It is world's first laser repeater and is currently exported to Japan.
Patents for the repeater are pending in Korea, Japan and China.
Since the IMT-2000 laser repeater requires low maintenance and installation costs, it is expected to attract huge demand.
Features
- Huge power laser repeater
- Broad band or channel type
- Auto gain control/Auto limit control
- Saving fixing experance
- CDMA
- Microprocessor control/ Auto
- Multi ray cell establishment
- Easy update to dcs.
