Descrição do produto
Wireless Coverage Expansion Fiber Optical DAS Supports 4G/LTE, 5G NR 1800/2100/3500MHz
Product Overview

Digital Fiber Optical DAS supporting 4G, 5G and Emergency Services across 1800/2100/3500MHz frequency bands. This 2Watt Digital Optical Repeater System features 33dBm Digital Optical dual band 1800/2100/3500MHz Amplifier DAS Repeater technology.

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 support both voice traffic and high-volume data from smartphones and connected devices, requiring sophisticated DAS designs with high Signal-to-Noise plus Interference Ratio (SNIR) for optimal throughput.

ATNJ integrates small cells and Wi-Fi solutions into our portfolio, providing comprehensive wireless network coverage. Small cell solutions target small to medium enterprises with focused coverage and capacity, while Wi-Fi solutions help offload network traffic in hotspot areas.

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 - Fiber optic transmission over several kilometers with minimal attenuation
  • Multi-band and multi-operator support - Simultaneous handling of 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
