Fiber Optic Links

AFL - 500 Analog Fiber Optic Link

1. The AFL - 500 is a Perfect Solution when you need to:
2. Transfer an Analog Signal from a Noisy Environment.
3. Isolate a Signal from High Voltage Sources.
4. Eliminate Ground Loops.
5. Have Accuracy and High Signal / Noise Ratio.
6. Have an Excellent System Reliability.

By combining Fiber Optic Technology with Advanced Proprietary Hardware, we provide Researchers and Industry with the means to isolate a Signal from Electrically Hostile Environment, Transmit it over upto 100km 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 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”.

1. The AFL - 500 Consists of the Following Components:
2. An Analog Fiber Optic Transmitter: AFL - 500 / Tx
3. An Analog Fiber Optic Receiver: AFL - 500 / Rx
4. Upto 50km of of Glass Fiber (30dB Optical Budget using Single-mode Fiber)

The Link is connected between the Signal Source at the Transmitter and the Signal Output at the Receiver

1. Advantages:
2. Low Noise Transfer of Analog or Digital Data (such as RS-232 Interface), particularly beneficial in Electrically Noisy Environments and for Transmission over Long Distance.
3. For Medical Tests: The Patient is Isolated from Data Acquisition System and from any Other High Voltage Source.
4. 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.
5. Isolates Delicate Test Equipment from Computer-generated Noise and Spikes: Noises from Computer do not return into your System.
6. Eliminates the formation of “Ground Loops” (when Two Instruments are connected to Separate Power Lines or have a Difference between their Ground Voltage Potentials).
7. Total Protection of Signal Processor's Input Stage from Accidental Sensor Malfunction (e.g. Short to Mains Voltage or a Lightning Shock).
8. Replaces bulky coaxial cables with compact fiber optic cables - especially important when rewiring existing ducts.
9. Transfers Analog Signals to distances of upto 100km with very high accuracy.

1. Technical Specifications:
