Scalable Digital Fiber Optic DAS Supports 4G 5G and Public Safety Bands Simultaneously
Product Overview
5Watt Digital Optical Repeater System 37dBm Digital Optical Tri-band 1800/2100/3500MHz Amplifier DAS Repeater
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.
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.
Features
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
