330--350MHz DMR Digital Active DAS System

Digital Optical Repeater (DOR) is an in-building or outdoor signal coverage solution that converts RF signals to digital optical signals for transmission over fiber optics between a Master Unit (MU) and Remote Units (RUs). It 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.

2Watt Digital Optical Repeater System 33dBm VHF Digital Optical 340MHz Amplifier DAS Repeater

• 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

• Support multi-band system
• Optical transmission up to 10km (max.)
• Support OMS Lite local/remote control
• Low noise and high reliability
• Each master unit can support 8 remote units
• Support to monitor donor signal parameters for easy optimization and troubleshooting
