Notes:

1. Solder time less than 5 seconds at temperature extreme.

Notes:

1. Threshold current is based on the two line intersection method specified in Telcordia GR468-Core. Line 1 from 4 mA to 6mA. 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 0.25 mA test interval points.

4. Using data points taken for slope efficiency above, ΔL/ ΔI shall be calculated for each adjacent pair of points.
