Rain Fade Diversity Link System

Many of the new High Throughput Satellites (HTS) operate at Ka-Band which is very susceptible to weather conditionsViaLite‘s Rain Fade Diversity system (L-Band HTS 700-2450 MHz) allows signals to be taken from an antenna located at a geographically diverse location where the weather is better within the satellite’s footprint – typically 50-100 km away. This is done without disruption of the data feed and with timing compensation to ensure continuity of service for the user.

The system was a finalist for Teleport Technology of the Year!

  • Rain fade solution for switching between teleports
  • Ideal for 500 MHz and 800 MHz bandwidths used in High Throughput Satellites (HTS) – also full 700-2450 MHz capability
  • Complete end-to-end system design
  • Full system testing over required distance prior to shipment
  • Time delay compensation between teleports
  • DWDM allowing 4-96 links per strand of fiber
  • LNB/BUC power and on-module LNB switching options

    Further Benefits

    • DWDM 10MHz Reference and SNMP/Ethernet available
    • Extreme temperature operation
    • True Plug and Play
    • Complete range of DWDM complementary products available
    • 5-year warranty as standard

     

    Ultra-wide dynamic range

    One of the system’s key features is the ultra-wide dynamic range. This allows wider bandwidths to be transmitted including the entire 700-2450 MHz.  For High Throughput Satellites (HTS), typical bandwidths are 500 and 800 MHz. Demand for increased capacity in satellite communication continues to drive the industry to use HTS at these higher frequencies, such as Ka-Band, which is particularly susceptible to rain fade.

    Due to the complexity of these systems, ViaLite offers system design and installation assistance. Please contact us for details.

     

    Manned from a single control room

    ViaLiteHD long distance links can also be controlled remotely using SNMP or Ethernet. This means multiple, unmanned teleport sites can be manned from a single control room, opening up new possibilities for teleport design.

     

    DWDM – 96 links per fiber

    The optional use of Dense Wave Division Multiplexing (DWDM) allows up to 96 links to be sent along a single fiber.  These can be setup for short interfacility links (IFLs), as well as over long distances. The DWDM massively reduces the fiber count, minimizing fiber leasing/operational costs.  DWDM requires the use of multiplexers, amplifiers and dispersion compensation.

     

    Available on Dark and Lit Fiber

    The system is available for dark fiber and also now lit fiber, through a specific choice and design of ViaLite DWDM components.

    Lit fiber can be a more cost-effective option for teleport operators.
