4G/LTE 5G NR Quad band 800/1800/2100/2600MHz In-Building Low Noise Digital Fiber Optical Multi Distributed Antenna System
This Digital Fiber Optical DAS supports 4G, 5G, and emergency services across 800/1800/2100/2600MHz frequency bands. The 2Watt Digital Optical Repeater System with 33dBm Digital Optical dual-band amplifier provides comprehensive signal distribution solutions for in-building wireless coverage.
System Overview
Distributed Antenna System (DAS) remains the most effective and reliable solution for in-building wireless coverage and capacity. As people spend most of their time in indoor environments, reliable wireless connectivity has become essential. Modern networks must handle both voice traffic and large data volumes from smartphones and connected devices, requiring sophisticated DAS designs with high Signal-to-Noise plus Interference Ratio (SNIR) for optimal throughput.
Key Components
  • Master Unit (MU) / Head-End Unit - Converts RF signals from base stations into optical signals for long-distance fiber transmission, 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 for minimal loss signal distribution
  • 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 component adjustment
System Features
  • 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 performance
  • Scalable and flexible architecture - Easy addition or reconfiguration of remote units for expanded coverage
  • Easy integration with existing networks - Supports CPRI/eCPRI interfaces and hybrid deployment with small cells
