ViaLite’s RF links meet US WGS standard

ViaLite Communications’ RF over fibre links have been confirmed to be compliant with the US Army's Wideband Global SATCOM (WGS) standards, the company announced on 18 August.

The qualification was achieved after the successful testing of the ViaLiteHD RF over fibre transmission equipment in conjunction with a systems integrator. During the tests, ViaLite’s high performance L-Band HTS RF over fibre links delivered better than -60 dBC at 10 dBm input power.

RF over fibre is a technology that describes the conversion of an RF signal into an optical signal and then back to an RF signal. In this architecture, a data-carrying RF signal with a high frequency usually greater than 10 GHz is imposed on a light wave signal before being transported over the optical link.

Following qualification, ViaLite‘s links can be used to connect ground stations for the US military's WGS system.

The relevant standard, MIL-STD-188-164, is a series of technical standards and design objectives relating to interoperability and performance to long haul and tactical communications systems.

RF over fibre systems can prevent attempts to eavesdrop or corrupt critical operational data. The fibre is also immune to electromagnetic pulse strikes and enables antennas to be located at greater distances away from assets.
