1. The Tracking Error is defined as the normalized change of output power relative to the operating power over case temperature range 0 °C to 75 °C, at constant back face monitor current corresponding
to the operating power at 25 °C.
2. The Tracking Ratio is a measure of the front-to-back tracking when the output power is varied. On a plot of optical power versus back-face photocurrent, a straight line is drawn between the minimum
power (20 mW) and the operating power Pop points. The tracking ratio is defined as the ratio between measured optical power (shown as data points on the plot) to the value derived from the straight line.
