330--350MHz DMR Digital Active DAS System

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.

• 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
