switched on if power supply is above V_TH after t_RES.
3. Transmitter meets ANSI T1E1.2, SONET OC-3 and OC-12, and
ITU-T G.957 mask patterns.

Notes
1. Minimum average optical power at which the BER is less than
1x10^-12 or lower. Measured with a 2²³-1 NRZ PRBS as recom-
mended by ANSI T1E1.2, SONET OC-3 and OC-12, 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, AC/DC for data
DC/DC, AC/DC, AC/AC PECL for Signal Detect
PECL compatible. Load is 50 Ω into V_CC –2 V for data, 270 Ω (3.3 V)
to V_EE for Signal Detect. Measured under DC conditions. For
dynamic measurements a tolerance of 50 mV should be added.
V_CC=3.3 V. T_AMB=25°C.
5. Max. output current high: –0.4 mA (drive current)
low: +2.0 mA (sink current)
6. AC/AC for data. Load 50 Ω to GND or 100 Ω differential. For dynamic
measurement a tolerance of 50mV should be added.
