point2point DC to 2MHz / DC to 10MHz
PPM’s point2point DC Analogue Fibre-Optic-Link provides a high performance analogue instrumentation system which produces great benefits for users who require a solution to electrical interference and noise problems in signal monitoring and distribution. The electrical input/output interface to the system is analogue, and this means that the link is transparent to almost any data format or signal type.
The point2point DC Transmitter converts the analogue input signal into an optical digital signal for transmission over the optical fibre. At the Receiver, the signal is converted back into an electrical signal. This high speed Analogue-to-Digital conversion technique has many advantages over conventional analogue solutions as it produces very high levels of accuracy and stability.
