Notes:
4. Performance in response to a signal from the transmitter driven with the recommended circuit at 1-125 MBd over 1 meter of plastic
optical fiber or 1 meter of HCS® fiber with F07 plugs.
5. Terminated through a 50 Ω resistor to VCC - 2 V.
6. If there is no input optical power to the receiver, electrical noise can result in false triggering of the receiver. In typical applications,
data encoding and error detection prevent random triggering from being interpreted as valid data.
