Line 1 from 4 mA to 6 mA. Line 2 from 0 mA to 0.5 mA. (2) Series Resistance is the slope of the Voltage-Current line from 5 to 8 mA. (3) Slope efficiency, is the slope of the best fit LI line from 5 mA to 8 mA using no larger than .25 mA test interval points. Measured with a 50/125 µm fiber. (4) Linearity—Using data points taken for slope efficiency above, data L/delta I shall be calculated for each adjacent pair of points. |
