point2point AC Coupled Analogue Fibre Optic Links
PPM’s point2point range of AC Analogue Fibre Optic Links are high performance analogue data transmission systems, which provide great benefits to users who require a solution to electrical interference and signal attenuation problems in signal monitoring and distribution over distance.
The user applies an RF signal to the input of the Optical Transmitter. The signal is amplified and conditioned, and converted into an optical signal for transmission over the optical fibre.
At the Optical Receiver, the optical signal is converted back into an electrical signal.
Due to the analogue nature of this technique, the link may be used to convey data of almost any format within the specified frequency limits.
The low noise figure of the point2point system allows the link to be used in DEF STAN 59-411 testing including DRE04 Electric Field Radiated Emissions Installed Antenna. The low noise figures of the point2point links enable detection and measurement of small disturbances, even when a considerable distance is required from the DUT.
