For 10/100 Ethernet, please see the SNMP card.

The ViaLiteHD Ethernet fiber optic link provides highly reliable, full duplex transmission of Ethernet signals over two single-mode optical fibers for distances of 1 m to 50 km.

  • GbE media converter
  • No special signal coding requirements
  • Immunity to electrical interference
  • SNMP compatible
  • 5-year warranty as standard


Product Inquiry


  • Available in standard wavelengths, as well as CWDM and DWDM for integration into existing networks or long-haul applications
  • GbE link works just like a piece of copper cable
  • Can be rack-mounted or fitted into a ViaLite Satcom6 enclosure.



This link is used in a wide variety of applications:

  • Industrial control and monitoring
  • Satellite communications monitoring and control (M&C)
  • SCADA and data communications links
  • Military tactical networks
  • Time server and clock signal distribution
  • Cellular and TETRA base station software upload and system control.

The ViaLite Ethernet 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.

– 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.
