The 732T/R Fiber-Optic Link is designed for short-haul transmission of electrical signals for applications in which using electrical conductors are not appropriate. The 732T/R provides transparent transmission of AC and DC information without the undesirable effects of EMI pick-up noise. Units are sold as a transmitter/receiver pair.
The Model 732T/R is purely an analog device; there is no analog to digital conversion. The input voltage signal is converted to a current and used to drive a LED. The output of the LED is detected by a PIN photodetector in the receiver, converted to a voltage then amplified. The gain of the receiver amplifier is tuned to provide transparent transmission. The receiver gain and DC offset are adjustable by the end-user to calibrate the transmitter and receiver pair when installed.
|Model||Type||TX Input||RX Output||Dynamic Range||Wavelength||Features|
|732TR||Analog||±2.5 V or 0-5 V (50 Ω or 33 kΩ)||±2.5 V or 0-5 V (into 1 kΩ)||55 dB (voltage)||850 nm||DC coupled|
Note: Dynamic range is measured from peak signal to RMS noise; fiber-optic links require ±15 VDC supply.
Optional 10 meter long cable available (ST to ST, 62.5/125 µm multimode, PVC simplex) for additional cost.
