Helios® Multi-bands Analog Fiber Optical Repeater

Universal Multi-Band, Multi-Service, Economic, Flexible Wireless Coverage and Capacity


 With the development of mobile communication technology, more and more new communication technologies (like 4G) are being adopted. Hence, telecom operators have to handle multi-system simultaneity and provide multi-system (2G/3G/4G) services in coverage area simultaneity.

Helios® conventional Multi-Band Analog Fiber Optic Repeater System is an conventional technology and is designed to simultaneity solve problems of 2G & 3G & 4G multi-band weak mobile signals in areas far away from the 2G & 3G & 4G Base Stations (BTS) and have fiber optic cable network available.

Helios® Multi-Band Analog Fiber Optic Repeater System mainly consists of two main equipment as follows:

  • Fiber DAS Donor HUB Unit – Optic Master Unit (OMU): to captures the respective 2G & 3G & 4G BTS signals via direct coupler closed to respective 2G & 3G & 4G BTS, then converts these signals into optical signal and transmits to the Remote Units via fiber optic cable.
  • Fiber DAS Optic Remote Unit (ORU): it will be installed on target coverage site with an IP-67 Case or a compact standard 19”/5U single chassis and supports upgrading from Single Band to Dual Band/ Tri Band and even Quad Band with just adding separate RF Cards easily

Features & Benefits

  • Supports up to four frequency bands (GSM/DCS/UMTS/LTE FDD/LTE TDD)
  • One Master Unit can support up to 8 Remote Units by STAR connection
  • One IP-65 Remote Unit can support up to 2 technologies and also can be expanded with multiple ORUs cascaded.
  • High gain linear wide-band power amplifier technique with reliable performance, support multi-carriers.
  • Scalable Output power +37dBm ~ +43dBm for option
  • RJ-45 port as LAN Port to support IP WEB Browser GUI for local control
  • Additional RJ-45 port as WAN Port to support remotely access through Internet/Intranet/VPN
  • Built-in 2G/3G/4G wireless modem (Option) for remote monitoring by SMS or Data Link
  • Details repeater parameters and status can be monitoring by built-in web interface, such as RSSI, temperature, output power level, gain, ATT, return loss, VSWR, Optic link, PA state and etc
  • Unique compact IP-65 rated mRRU design for pole and wall mounte
  • Flexible IP-65 rated waterproof Hot-swappable external Fan Tray with four high-performance temperature-controlled fans for increasing ventilation and better airflo
  • Option 19” stackable rack-mounted cabinet with modular design is available based on project requirement
  • iBwave VEX component files are available for your in-building wireless and fiber network design and deployment projects
  • SNMP V2 & V3 support with a MIB File


To expand signal coverage of fill signal blind area where signal is weak or unavailable.

  • Outdoor: Airports, Tourism Regions, Golf Courses, Tunnels, Factories, Mining Districts, Villages etc.
  • Indoor: Hotels, Exhibition Centers, Basements, Shopping Malls, Offices and Packing Lots etc.
