Description
330-350MHz DMR Digital Active DAS System
Public Safety DAS Long Distance VHF Digital Active DAS System
Product Overview
The 2Watt Digital Optical Repeater System is a high-performance VHF Digital Optical 340MHz Amplifier DAS Repeater designed for public safety applications. This Digital Optical Repeater (DOR) provides comprehensive in-building or outdoor signal coverage by converting RF signals to digital optical signals for transmission over fiber optics between Master Units (MU) and Remote Units (RUs).
The system enables low-loss, long-distance distribution of cellular signals (2G to 5G) with high dynamic range, precise time delay management, and multi-band/multi-operator support capabilities.
Key Components
  • Optical-to-Electrical (O/E) Converter: Converts incoming optical signals to electrical signals
  • Digital Signal Processor (DSP): Performs signal regeneration, error correction, clock recovery, and noise reduction
  • Electrical-to-Optical (E/O) Converter: Re-transmits the regenerated digital signal as amplified optical pulses
System Features
  • Multi-band system support
  • Optical transmission up to 10km (maximum)
  • OMS Lite local/remote control support
  • Low noise and high reliability operation
  • Each master unit supports up to 8 remote units
  • Donor signal parameter monitoring for easy optimization and troubleshooting
