VccT BiasCNT Data Input Optical Output
VccT < 3.1V X X OFF
Low X OFF
No Other
VccT > 3.1V High
Yes Laser bias and modulation signal output
X = Don’t care
Other = Less than +7.5dBm (peak)
High = Logic high level, Low = logic low level
No = No Data Input, Yes = Data Input,
OFF = Optical Power is less than –45dBm
