Notes:
1. The Laser Reset Voltage is the voltage level below which the V_CCT voltage must be lowered to cause the laser driver circuit to reset from an
electrical/optical shutdown condition to a proper electrical/optical operating condition. The maximum value corresponds to the worst-case
highest V_CC voltage necessary to cause a reset condition to occur. The laser safety shutdown circuit will operate properly with transmitter V_CC
levels of 2.5 Vdc ≤ V_CC ≤ 5.0 Vdc.
2. These outputs are compatible with 10 K, 10 KH, and 100 K ECL and PECL inputs.
3. These are 20-80% values.
4. Under recommended operating conditions.
