- Dec 18, 2017 -

The transmitting part is that the input electric signal with a certain code rate is driven by an internal driving chip to drive a semiconductor laser (LD) or a light emitting diode (LED) to emit a modulated optical signal with a corresponding speed, and an internal automatic power control circuit The output optical signal power remains stable. The receiving part is: a certain rate of optical signal input module by the optical detection diode into electrical signals. After the preamplifier output the corresponding rate of the electrical signal
