6 Popt = Pout,max at T=25°C
7 Minimum average optical power at which the BER is less than1x10E–10. Measured with a 1023 –1 NRZ PRBS as recommended by ANSI
T1E1.2, SONET OC-3, and ITU G.957.
8 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.
9 A decrease in optical power below the specified level will cause the SIGNAL DETECT to change from a High state to a Low state.
10 AC/AC for data. Load 50to GND or 100differential. For dynamic measurement a tolerance of 50mV should be added.
11 Supply current excluding Rx output load.
12 Source wavelength is 1550 nm, BiDi Tx and Rx is Off
