4. Optical and Electrical Characteristics of Transmitter Portion
Optical and electrical characteristics of transmitter portion are shown in
Table 2. Unless otherwise stated, minimum and maximum values are
specified over the operating ambient temperature, and humidity ranges, DC
power supply voltage range, from beginning to end of life, using 2
23
-1 pseudo
random bit stream with a 50% duty factor.
The logic sense for the DATA input is such that a logic “1”(High) corresponds
to the maximum level of an amplitude modulated light source (Light on), while
a logic “0”(Low) corresponds to a minimum level of an amplitude modulated
light source (Light off).
