Analog Fiber-Optic Link AFL-500

AFL-500
ANALOG FIBER-OPTIC LINK

Introduction

When you need:
  To transfer a signal from a noisy environment,
  To isolate the signal from high voltage sources,
  Accuracy and high Signal/Noise Ratio,
  Excellent system reliability -
- the AFL-500 is the perfect solution !

No other signal isolation method compares with
the AFL-500 Analog Fiber-Optic Link.

By combining fiber optic technology with advanced proprietary hardware, provides researchers and industry with the means to isolate a signal from electrically hostile environment, transmit it over up to 1 km to the data acquisition system, while conditioning the signal. This method eliminates the addition of noises generated by electrical machinery, line noises, ground loops and digital noise to your analog signals.

The AFL-500 consists of the following components:
  An Analog Fiber Optic Transmitter - AFL-500/TX,
  An Analog Fiber Optic Receiver - AFL-500/RX,
  Up to 1 km of of glass fiber.

The link is connected between the signal source at the transmitter (see Figure 1), and the signal input at the receiver.

Features

  Excellent signal isolation.
  Prevents ground loops and computer noise effects on your Analog Signals.
  Transfers analog signals to distances of up to 1 Km.
  Linearity: better than 0.1%.
  Low noise; S/N ratio: 86 dB.
  Input signal: Up to ±10 Volt @ DC-20 kHz.

Advantages

Low noise communication of analog or digital data (such as RS-232 interface), particularly beneficial in electrically noisy environments and for transmission over long distance.
  For medical tests: the patient is isolated from data acquisition system and from any other high voltage source.
  Optional instrumentation amplifier input stage provides a differential input, with an adjustable gain of 10-2,000, for direct connection of any sensor such as: strain gage, piezo, EEG & ECG, temperature, humidity, pressure, etc.
  Isolates delicate test equipment from computer-generated noise and spikes: noises from computer do not return into your system.
  Eliminates the formation of "ground loops" (when two instruments are connected to separate power lines or have a difference between their ground voltage potentials).
  Total protection of signal processor's input stage from accidental sensor malfunction (e.g. short to mains voltage or a lightning shock).
  Replaces bulky coaxial cables with compact fiber-optic cables - especially important when rewiring existing ducts.
  Transfers analog signals to distances of up to 1 km - with high accuracy.

Ordering Information

  The AFL-500 has a single-ended input in 3 ranges:
±10 V (standard) or ±1 V, ±100 mV.
  Single ended input (S) is standard.Differential input (D) may be ordered with input range of ±10 V, ±1 V, ±100 mV, ±10 mV, ±1 mV or adjustable (A).
  A stabilized power supply is also required for each side. It can supply up to 5 (optionally 10) receivers or transmitters.
