*1: When non-modulated signal (optical all high or all low level signal) is inputted, output signal is not stable.
When modulated optical high level signal is received, output signal is high.
When modulated optical low level signal is received, output signal is low.
The duty factor must be maintained between 25 to 75%.
*2: APF:All Plastic Fiber (970/1000μm). Length 1 Meter.
*3: Between input of transmitting module and output of APRX178.
