L-Band HTS 700-2450 MHz – HWDR

The ViaLite L-Band HTS – HWDR link boasts hyper-wide dynamic range (114 dB/Hz 2/3) and also allows for multiple channels to be sent down a single fiber. The link is ideal for the extremely demanding dynamic range applications associated with HTS and defense. It is based on the ViaLite Long Distance DWDM System technology used for site diversity or up to 600 km of antenna remoting.

  • Transmission distances of 0-50 km (DWDM)
  • Ideal for 500, 800 and full 1500 MHz bandwidths used in High Throughput Satellites (HTS)
  • Designed for Satcom and Defense – RF and fiber connections on the rear
  • Uses a regular L-Band HTS Receiver
  • 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
  • 5-year warranty as standard

L-Band HTS 700-2450 MHz – HWDR

Hyper-wide dynamic range

The Hyper-wide link 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.


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 standard L-Band HTS, 70-140 MHz, 10 MHz and in Tx and Rx configurations.


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.

Hardware formats

The L-Band HTS RF over fiber link is available in several formats:

– Single rack chassis card (Tx)

A fully populated 19” 3U ViaLiteHD rack chassis supports up to 26 links and accepts 13 RF cards, plus an SNMP card and dual power supply modules.  A 1U chassis accepts three RF cards or two RF cards with an SNMP card.

– Yellow OEM Link

The Yellow OEM Link has been designed for system integrators and equipment manufacturers to build the link into their own designs.

A range of support modules and accessories is also available, including indoor rack chassis units and weatherproof outdoor enclosures.

See our hardware formats guide for more information.


Options include:

  • 50Ω electrical connectors: SMA
  • 75Ω electrical connectors: BNC, F-Type
  • Optical connectors: SC/APC, FC/APC & E2000/APC as standard
  • ITU DWDM wavelengths
  • Test ports on Tx
  • Blind mate connectivity (SC/APC and SMA/BNC)
  • LNB control with 13/18VDC & 22kHz tone through RF connection.
