Our point2point AC
Analogue Fibre-Optic-Links provide a high performance analogue
data transmission system, which offers great benefits to users
who require a solution to electrical interference and signal
attenuation problems in signal monitoring and
distribution.
OPERATION:
The user applies an
electrical signal to the input of the Transmitter. The signal
is amplified and conditioned, and converted into an optical
signal for transmission over the optical fibre. At the
Receiver, the 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.

APPLICATIONS
-
Antenna Remoting.
-
IF Links.
-
Secure Transmission
(Tempest).
-
Pulse power
measurements.
-
Time and frequency
domain monitoring.
-
Signals containing a
wide range of frequency
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 low loss, enabling very
long path lengths with negligible degradation of
signal-to-noise.length.
- 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.
|
HIGH
PERFORMANCE
Our Fibre Optic Link offers
particular advantages:
- Wide, flat frequency response
for accurate transmission of broadband signals e.g.
squarewaves, double exponential pulses
etc.
- Electrically screened Shielded
Remote Module option for operation in high levels of
electrical interference.
- A range of input and output
signal levels.
- Wide dynamic range to permit
simultaneous monitoring of low and high level signals.
- Visual indication of received
optical signal level at Receiver.

SYSTEM
CONFIGURATION
The AC Analogue Fibre-Optic-Links belong to our
modular point2point product range, where the Transmitter or
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 Fibre Optic Cable.
USER SPECIFIED
PARAMETERS
The user can specify a number of link parameters to
suit any particular application including: signal level;
bandwidth, gain, and also a range of mechanical options
including ruggedised optical connectors and high strength
cable.
An option is
provided for a bi-directional RS232 link along a second fibre.
This provides a compact solution for transmission of the
user’s command or control
information.
