Fiber Optic applications require analog drivers and receivers operating in the megahertz region. This complete analog transmission system is suitable for optical communication applications up to 3 MHz. The transmitter LED is normally biased at 50 mA operating current. The input is capacitively coupled and ranges from 0 to 5 V, modulating the LED current from 0 to 100 mA. The receiver circuit is configured as a transimpe-danee amplifier
Fiber-optic link

The photodiode with 0 amp per watt responsivity generates a 50 mV signal at the receiver output for 1 /iW of light input.
