Our point2point DC
Fibre-Optic-Links provide 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. | |

APPLICATIONS
- EMC Test Chambers.
- Electrically noisy environments.
- Power distribution monitoring.
- High voltage monitoring and analysis.
- Automotive applications requiring monitoring of true
DC signals.
- Signals containing very low frequency or DC
components.
|
BENEFITS
The use of optical fibre has a number of inherent
advantages over conventional copper based alternatives:
- Immunity to electrical interference, so the signal is
not corrupted by radiated interference.
- It is non-conductive, thus providing an intrinsically
safe transmission path for the monitoring of equipment at
hazardous voltages.
- It uses highly flexible and small diameter
cable.
- Elimination of ground
loops.

Our DC-1MHz Analogue Fibre-Optic-Link offers particular
advantages:
- Analogue-to-Digital Conversion technology for high
accuracy, low drift and high reliability.
- True
DC coupling for monitoring of DC and very low frequency
signals.
- High
DC stability and path length independence due to the use of
digital signal transmission.
- Electrically screened Shielded Remote Modules for operation
in high levels of electrical interference.
- A
range of input and output voltage levels.
- Wide
dynamic range suitable for simultaneously monitoring low and high
level signals.

SYSTEM CONFIGURATION
The
DC-1MHz Analogue Fibre-Optic-Link belongs to our modular
point2point product range, where Transmitter and Receiver units can
be delivered in Remote, Shielded Remote or Plug-In Module options. A
typical system configuration comprises a Shielded Remote Transmitter
Module connected to a Plug-In Receiver Module via a lightweight
Fibre Optic Cable.
