6. Optical and Electrical Characteristics of Receiver Portion
Optical and electrical characteristics of receiver portion are shown in Table 3. Unless
otherwise stated, minimum and maximum values are specified over the operating ambient
temperature, and humidity ranges, DC power supply voltage range and wavelength range, from
beginning to end of life, using a 2
