Satellite IF 70-140MHz

ViaLite’s Satellite Intermediary Frequency (IF) RF over fiber links cover the 20-200MHz bandwidth range; providing cross-site connectivity for standard 70-140MHz IF signals.  These links typically sit between the up-/down-converter near the antenna and operations room switch matrix or modems.

  • Transmission distances of up to 10km (1310nm) and up to 50km (1550nm)
  • Designed for Satcom – RF and fiber connections on the rear
  • 13/18V and 22KHz 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
Product Inquiry
Satellite IF 70-140MHz

The Satellite IF fiber links are designed to cover the traditional cross-site bands, with the same features as the L-Band HTS links.

 

Plug and Play

The links can be either plug-in or blind mate enabling simple installation.  Due to the simple plug in nature of the cards they can be positioned in any slot in the 19” rack and can be mixed with L-Band HTS, 10MHz and in Tx and Rx configurations.

 

RF and Digital

As with all the links, it is possible to have a 20kb/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 the ViaLite splitters and switches.

The Satellite IF RF over fiber link is available in several formats:

– Single rack chassis card / Dual rack chassis card (Rx/Rx, Tx/Tx or Tx/Rx)

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.

– Blue OEM Link

The ViaLite standalone Blue OEM Link offers a compact, single link solution.

 – Blue2 Link

The Blue2 Link is a dual-solution OEM which can be setup as 2x transmitters, 2x receivers or a transceiver, as required.

– 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.
