Digital Fiber Optical DAS supports 4G, 5G, and emergency services across 900/1800/2600MHz frequency bands. This 2Watt Digital Optical Repeater System with 33dBm output power provides reliable in-building wireless coverage and capacity solutions.

Distributed Antenna System (DAS) remains the most effective solution for indoor wireless connectivity. As wireless networks must handle increasing data volumes from smartphones and connected devices, DAS systems require high Signal-to-Noise plus Interference Ratio (SNIR) to achieve optimal throughput.

• Master Unit (MU) / Head-End Unit - Converts RF signals from base stations into optical signals for long-distance transmission over fiber, supporting multiple bands and operators
• Remote Unit (RU) - Converts optical signals back to RF for indoor or tunnel coverage, featuring low noise figure and high output power
• Optical Distribution Network (ODN) - Includes single-mode fiber cables, optical splitters, and patch panels that distribute signals with minimal loss
• Expansion Unit (EU) - Provides additional fiber ports and cascading capability for scalable DAS architecture in large venues
• Network Management System (NMS) - Software platform for remote monitoring, fault diagnosis, and real-time adjustment of system components

• Low signal loss over long distances - Transmits RF signals over several kilometers with minimal attenuation
• Multi-band and multi-operator support - Simultaneously handles 4G/LTE, 5G NR, and public safety bands
• High signal quality with low noise figure - Digital processing ensures excellent SNR and EVM
• Scalable and flexible architecture - Easy addition or reconfiguration of remote units
• Easy integration with existing networks - Supports CPRI/eCPRI interfaces and hybrid deployment
