Sending RF signals over optical fibre offers many advantages such as ultra low RF loss over very long distances, signal immunity to electric and magnetic fields and easy deployment. RF over fibre is an ideal replacement for coaxial cable technology and Chronos offers systems that are plug-and-play replacements of existing copper networks from its supplier PPM. RF over fibre links are typically used in satellite comms, broadcast communications, antenna remoting, military and security, GPS timing, cellular and specialist signal distribution applications.

GPS RF Fibre Optic Link

PPM's ViaLite GPS RF Fibre-Optic-Link provides high reliability, transparent cross-site connection between a GPS antenna and a GPS receiver.

GPS RS422 Fibre Optic Link

PPM's ViaLite GPS RS422 Fibre-Optic-Link provides a high reliability connection for the transmission of RS422 signals over optical fibre for distances of up to 20km.


The Metro-GPS product offers a cost effective and simple method for transporting GPS RF signals to locations remote from the GPS antenna. Metro-GPS is offered in either single or dual channel format with further options of automatic signal switch over for situations where redundancy is required for maximum signal uptime.

TimeProvider GPS Antenna Fibre Optic Link

Do you have a need to use PRC quality, GNSS based timing references within an electrically isolated environment? Getting the GNSS antenna signal into the isolated area would have been impossible, but this novel solution from Chronos delivers the timing reference over optical fibre.

ViaLite Combined RF & Digital Fibre Optic Link 10MHz - 4200MHz

Simultaneous flows of RF and Digital Data Streams over just one Fibre. PPM has enhanced the ViaLite range with two important developments: bandwidth extended to 4.2GHz enabling Satellite Operators and Service Providers to pull-down C-band traffic for storage and redistribution; and a new modulation technique has been developed to allow a combination of both analogue and digital feeds onto a single optical channel.
