Optical transmission detection circuit

Published:2011/5/5 7:51:00 Author:Nicole | Keyword: optical transmission detection circuit

Optical transmission detection circuit
In this circuit, phototransistor and four operational amplifier take the action of total energy detector, to detect the total energy of pulse optical transported by the optical cable communication system. If the light intensity of singal source remains the same, then this circuit can be used to test and compare the situation of optical fiber, it also can be used to detect the change of light intensity and pulse width. If the minimum pulse width is 10μs, then the response of this circuit to light intensity is linear. A2 has the function ofRC integrator, the output voltage is directly proportional to the total received light energy. A4 is used to compare with the fixed level. (View)
