Electrical and Optical Characteristics –40°C to +85° unless otherwise stated. Parameter Symbol Min Typa a. Typical data are at 25°C. Max Unit Conditions Reference 30-mA, 1-mm POF 200-μm PCS PT,30 –6.5 –18 –1 –12 2 –9 dBm IF,DC = 30 mA Notes b, c Figure 2 b. Optical power measured with polished connector end face at the end of 1 meter of 1-mm diameter POF with a numerical aperture (NA) of 0.5, or of 200-μm diameter PCS, with NA = 0.37, using a large area detector. c. Minimum and maximum values for PT over temperature are based on a fixed drive current. 10-mA,1-mm POF PT,10 –11.5 –6 –3 dBm IF,DC = 10 mA Notes b, c Figure 2 5-mA,1-mm POF PT,5 –14.5 –9 –6 dBm IF,DC = 5 mA Notes b, c Figure 2 3-mA, 1-mm POF PT,3 –16.5 –11 –8 dBm IF,DC = 3 mA Notes b, c Figure 2 30-mA, 1-mm POF, 25°C PT,30,25 –3 –1 1 dBm IF,DC = 30 mA T = 25°C Notes b, d Figure 2 d. This parameter refers to initial (0hrs) operation at 25°C only. Any degredation by aging effects of the LED as well as temperature effects are not considered.
