Notes:

1. The Laser Reset Voltage is the voltage level below which the VCCT 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 VCC voltage necessary to cause a reset condition to occur. The laser safety shutdown circuit will operate properly with transmitter VCC

levels of 2.5 Vdc ≤ VCC ≤ 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.
