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.
3. Transmitter meets ANSI T1E1.2, SONET OC-3 and ITU-T G.957 mask
patterns.

Notes
1. Minimum average optical power at which the BER is less than
1x10^-10 or lower. Measured with a 2²³-1 NRZ PRBS as recom-
mended by ANSI T1E1.2, SONET OC-3 and ITU-T G.957.
2. An increase in optical power of data signal above the specified level
will cause the SIGNAL DETECT to switch from a Low state to a High
state.
3. A decrease in optical power of data signal below the specified level
will cause the SIGNAL DETECT to switch from a High state to a Low
state.
4. DC/DC, PECL for Signal Detect
PECL compatible. Load is 50 Ω into V_CC –2 V for data, 500 Ω to V_EE
for Signal Detect. Measured under DC conditions. For dynamic mea-
surements a tolerance of 50 mV should be added. V_CC=3.3 V/5 V.
T_AMB=25°C.
