Description
The JMA Wireless TRU7F8PWE/48-WS is a TEKO enhanced low power remote unit designed for 700 MHz and 800 MHz public safety communications. It operates within a compatible TEKO distributed antenna system (DAS) to extend radio coverage throughout buildings, campuses, tunnels, and other challenging coverage areas.
This model uses a nominal -48 VDC power supply and connects to the TEKO master unit over single-mode optical fiber. Wavelength division multiplexing (WDM) supports uplink and downlink communication over the same fiber, while automatic gain control helps maintain consistent system gain as optical losses vary. Passive cooling provides fanless operation.
