2. Laser power is shut down if power supply is below V_TH and
switched on if power supply is above V_TH after t_RES.

Notes
1. Average optical power at which the BER is 1 x 10E–12. Measured
with a 2⁷–1 NRZ PRBS and ER=9 dB.
2. An increase in optical power above the specified level will cause the
SIGNAL DETECT output to switch from a Low state to a High state.
3. A decrease in optical power below the specified level will cause the
SIGNAL DETECT to change from a High state to a Low state.
4. AC/AC for data. Load 50 Ω to GND or 100 Ω differential. For dynamic
measurement a tolerance of 50 mV should be added.
5. Supply current excluding Rx output load.
