L-Band HTS 700-2450 MHz (50Ω)

The ViaLite L-Band HTS link (700-2450 MHz) covers distances of 1m to 50 km and is the most commonly used RF over fiber link in Satellite Communications.  A Long Distance Link DWDM system up to 600 km is also available.

  • Transmission distances of up to 10 km (1310 nm) and up to 50 km (1550 nm)
  • Ideal for 500, 800 and full 1500 MHz bandwidths used in High Throughput Satellites (HTS)
  • Designed for Satcom – RF and fiber connections on the rear
  • 13/18 V and 22 kHz tone LNB control
  • True Plug and Play
  • 50 and 75 ohm
  • Superior linearity and low noise
  • SNMP or web GUI interface for easy set-up, remote monitoring or control

Plug and Play

The links can be either plug-in or blind mate and are completely plug and play, enabling simple installation.

The rack chassis cards can be positioned in any slot of a ViaLite 19” rack and can be mixed with 70-140 MHz, 10 MHz and in Tx and Rx configurations.

Ultra-wide dynamic range

One of the link’s key features is the ultra-wide dynamic range.  This allows wider bandwidths to be transmitted.  For example, 500 to 800 MHz signals typically used in High Throughput Satellites (HTS).  Demand for increased capacity in satellite communication continues to drive the industry to use HTS at these higher frequencies.

RF and Digital

As with all the links, it is possible to have a 20 kb/s serial digital channel multiplexed in with the RF signal.  This allows for control of other equipment such as antenna controllers, BUCs or converters.

1:1 Redundancy

To ensure five nines reliability, the links are available in a full 1:1 redundancy configuration, in both rack mount and outdoor enclosures, using ViaLite splitters and switches.

Other link options include L-Band HTS + Reference links (integrating 5-50 MHz reference signals) and ViaLite Long Distance DWDM links, which cover distances between 0-600 km.
