AFL-300 ANALOG FIBER OPTIC LINK

Actual Size: 61 x 61 x 28mm (box only)
Price starts from $962.- per pair (Transmitter and receiver units), basic +/-10V configuration, Multi-Mode.

When you need:
  To transfer an analog signal from a noisy environment,
  To isolate the signal from high voltage sources,
   Eliminate ground loops,
   Transfer Analog signals Accurately at high Signal/Noise Ratio,
   Have excellent system reliability,
The AFL-300 is the answer.

By combining fiber optic technology with advanced proprietary hardware, A. A. Lab Systems provides researchers and industry with the means to isolate a signal from electrically hostile environment, transmit it over up to 1.6 km to the data acquisition system, while conditioning the signal (over 50Km using Single Mode transceivers). This method eliminates the addition of noises generated by electrical machinery, line noises, ground loops and digital noise to your analog signals.The AFL-300 Analog Fiber Optic Link is used for transferring Analog Signals over a Fiber Optic Link. This product is also known as "Analog Optical Link" or "Analog Fiber Link". The unit has optional interface to 4-20 mA (or 0-20mA) current loop signals. The input may be 4-20mA (or 0-20mA) from a sensor and the output may be 4-20mA to your controller (or 0-10V proportional to the current input).

The AFL-300 consists of the following components:
  An Analog Fiber Optic Transmitter - AFL-300/TX,
  An Analog Fiber Optic Receiver - AFL-300/RX,
  Up to 3 km of of Multi-mode glass fiber or 50 Km of Single-mode fiber (optional).
Optical budget with Single Mode transceivers: 30 dB

The link is connected between the signal source at the transmitter (see Figure 1), and the signal output 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 3 Km (50Km with Single Mode transceivers)
  Linearity: better than +/-0.05%.
  Low noise; S/N ratio: 86 dB.
  Input signal: Up to ±10 Volt @ DC-5 KHz.
  Low Offset Temperature Drift: Better than 100 ppm/deg.C
  Very small size: only 61 x 61 x 28 mm
  Low cost: $794.- per pair (Rx + Tx).
  Differential Option with 1-100 gain for low level signals and better noise immunity.
  4-20 mA current loop interface (optional) .
  Can work under Ionizing radiation (Nuclear applications)

Ordering Information
  The AFL-300 is input single-ended, in 3 ranges:
±10 V (standard) or ±1 V or ±100 mV.
  Single ended input (S) is standard. Differential input (D) may be ordered with input range of ±10 V, ±1 V, ±100 mV, ±20 mV or adjustable (A).
  A stabilized power supply is also required for each side. It can supply power for up to 5 (optionally 10) receivers or transmitters.
Supply can be modified to 24Vdc.

EXAMPLE:
TRANSMITTER / RECEIVER PAIR:
AFL-300 - 1V - 10V - S - R
Where:
 1 V = Input voltage range(10V is standard).
 10 V = Output voltage range(standard).
  S = Single Ended(D=Differential is optional).
 R = Range in meter
 SM = Single Mode Transceivers

Current loop (4-20mA or 0-20mA) interface is available. Please contact factory.
