1 Optical power measured from the end of a 1mm core plastic fiber 1m long, NA=.47 and LED IF =20 mA.

4 Distance when mated with the IF-D97 photologic detector.

2 Rise and fall times are measured from the 10% to 90% and 90% to 10% points.

5 When matched with the IF-D98 photologic detector.

3 Exact operating distance depends on the photodetector selected and in some cases the electrical bandwidth of accompanying circuits.

1 Rise times and fall times are measured from the 10% to 90% and 90% to 10% points, respectively.

2 Optical power measured from polished end of 1000 µm plastic optical fiber connected to Helium Neon laser producing radiation at 632.8 nm in wavelength.

3 λ=660 nm.

4 Threshold is the optical power that the photologic switches from a low to high, or from high to low.

5 This device has internal gain control circuitry that makes it unsuitable for applications under 4 Mbps.
