= 3.3 V ± 5%)
1. 20% to 80%.
2. Internally biased and ac-coupled.
3. The transmitter is normally enabled and only requires an external voltage to disable.
4. The WDEA alarm becomes active when the optical wavelength deviates from the nominal center wavelength by more than 100 pm.
5. Set at 500 mV at nominal optical output power. Provides linear P
O
tracking (–3 dB = 250 mV, +3 dB = 1000 V).
6. Terminated into 200
to GND and 100
line-to-line.
