5G NR Fiber to The Antenna – FTTA

Utilizing ultra-wide bandwidth RF front-end design with Software Define Radio (SDR) architecture, Helios® 5G Digital FTTA™ (Fiber to The Antenna) system enables the most flexible, scalable and complete solution for addressing middleprise coverage and capacity needs for 5G NR. Helios® 5G Digital FTTA™ is a two-tier architecture consisting of the Outdoor Network Units (ONUs) and Active Antenna Units (AAUs):

  • Outdoor Network Units (ONUs): The ONU owns up to 4T4R RF paths and each RF path support max 100MHz bandwidth and can be configured to be FDD or TDD mode in factory, it has four 14Gbps SFP+ digital optic ports and supports up to 12 AAUs by star, chain, ring and hybrid network topologies, even up to 48 AAUs by adding OEUs in some scenarios. It generally be deployed outdoor and accesses & synchronize outdoor 5G BTS signal on air with embedded MIMO antennas by our patented 5G NR TDD synchronization algorithms, the signal is filtered and then converted to a digital CPRI data stream as well as synchronization signal. The digital CPRI packet data stream is transported via single mode fiber and received by the remote AAUs.
  • Active Antenna Unit (AAUs): The AAUs then convert the digital CPRI packet data stream back to RF and control the switcher to PA based on synchronization signal from ONU, then amplify the signal to the embedded MIMO services antennas. On the reverse path (uplink), the AAUs and ONU perform the inverse functions and delivery the signals back to the corresponding 5G Base Stations.

  • Compact & Fashion design for wall-mount, pole-mount and ceiling-mount
  • Full digital software and hardware platform with Ultra-wide RF front-end design and enables 4T4R RF path and each RF path supports maximum 100MHz bandwidth to meet the potentially huge bandwidth demand while ensuring superb 5G services
  • Patented 5G NR TDD synchronization algorithms based on SDR technique
  • 2*RJ-45 Port for Local Control and Alarming on an IP Web Browser GUI
  • Each ONU has four 14Gbps SFP+ digital optic ports and supports up to 12 AAUs by star, chain, ring and hybrid network topologies, even up to 48 AAUs by adding OEUs in some scenarios, such as subways and tunnels
  • SNMP V2 & V3 support with a MIB File
  • Innovative Power-over-Fiber (PoF) feature enables flexible & simplifies installation
  • Wireless backhaul for more fast, flexible and accurate deployment to improve 5G NR throughput on middleprise coverage
  • Peaceful coexistence with current 5G NR macro without any change & update on core network
