ANALOG FIBER OPTIC LINK
When you need:
By combining fiber optic technology with advanced proprietary hardware,
AFL-500 consists of the following components:
The link is connected between the signal source at the transmitter (see Figure 1), and the signal input at the receiver.
Excellent signal isolation.
Prevents ground loops and computer noise effects on your Analog Signals.
Transfers analog signals to distances of up to 50 Km.
Linearity: better than +/- 0.1%.
Low noise; S/N ratio: 86 dB.
Input signal: Up to ±10 Volt @ DC-20 KHz(DC to 30 KHz optional).
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.
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 100 km - with very high accuracy.
Input/output Range: ±10 V standard; ±1 V ±100 mV optional.
Linearity: +/-0.1% min.
Frequency Response: DC to 20 KHz (-3 dB)DC to 30 KHz optional.
Output Noise: < 1 mV rms (for 1:1 transmission ratio, DC-20 KHz. bandwidth).
Supply Voltage: ±15 V regulated, floating power supply.
Optical Fiber: Glass, 62.5/125 micron dia. Standard (up to 1 Km), 9/125 micron optional (up to 50 Km).
- Up to 100 Km with single mode fiber.
Dynamic Range: 86 dB (±10 V range).
- Input to Output - infinite voltage,
- Input/Output to Mains - standard 800V, Optional up to 2500 V,
- Battery operated - infinite voltage.
Optical budget using Single Mode transceivers: 30 dB.
/ RECEIVER PAIR:
AFL - 500 - 10
channel power supply (for one side)
operated power supply:
