1) _{Average optical power at which the BER is 1x10}–12_{. Measured with a 2}23_{–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.}
