AFL-200 Analog Fiber Optic Link is an OEM product designed especially for manufacturers who want to isolate analog signals inside or between their systems. The AFL-200 Analog Fiber Optic Link was designed for applications where low size, low power consumption and low cost are important. The unit transfers 1 analog signal and 2 digital signals to one direction. Analog signal may be within +/-10V @ DC-5KHz. bandwidth.The distance between the 2 boards can be from 0 to 1.6 mile (30 miles optional with Single Mode fiber).
AFL-200 Analog Fiber Optic Link
point   Excellent signal isolation.
point   Prevents ground loops and computer noise effects on your Analog Signals.
point   Transfers analog signals to distances of up to 1.6 Km (50Km. Optional).
point   Linearity: better than +/-0.05%.
point   Low noise; S/N ratio: 72 dB.
point   Input signal: Up to ±10 Volt @ DC-5 KHz.
point   Low Offset Temperature Drift: Better than 50 ppm/deg.C

point   Very small size: only 46 x 46 mm
point   Low cost: $380.- per pair (Rx + Tx) (@ minimum 10 pcs.). Samples available at $456.- per pair.
point   Differential Option with 1-100 gain for low level signals and better noise immunity.


Analog Bandwidth: DC-5KHz.
Digital Bandwidth: DC-20Kbps
Digital Bandwidth: 72dB
Supply Voltage: 12V+/-10%
Supply current: RX: 90mA, TX:60mA
Input Voltage Range: +/-10Vstd. or +/-5V or +/- 0.1V
Output Voltage Range: +/-10Vstd. or +/-5V
Non-Linearity Error: 0.05% @+/-10V range
Noise: Better than 0.5mV RMS
Input Impedance: 143KOhms

Optical budget with Single Mode transceivers: 30 dB
The transmitter can be modified to work at 5V@ 34mA instead of 12V@60mA with reduced optical budget (100m MM fiber), for "Power over fiber" and solar cell/battery powered applications.

point   Low noise transfer of analog or digital data , particularly beneficial in electrically noisy environments and for transmission over long distance.
point  For medical tests: the patient is isolated from data acquisition system and from any other high voltage source.
point  Optional instrumentation amplifier input stage provides a differential input, with an adjustable gain of 10-500,
for direct connection of any sensor such as: strain gage, piezo, EEG & ECG, temperature, humidity, pressure, etc.
point  Isolates delicate test equipment from computer-generated noise and spikes: noises from computer do not
return into your system.
point  Eliminates the formation of "ground loops" (when two instruments are connected to separate power lines or have a difference between their ground voltage potentials).
point  Total protection of signal processor's input stage from accidental sensor malfunction (e.g. short to mains
voltage or a lightning shock).
point  Replaces bulky coaxial cables with compact fiber optic cables - especially important when rewiring existing ducts.
point  Transfers analog signals to distances of up to 1.6 km - with very high accuracy.
