BiasCNT

BiasCNT Enable Duration

Interval of BiasCNT Signal

VccT	BiasCNT	Data Input	Optical Output
VccT < 3.1V	X	X	OFF
VccT > 3.1V	Low	X	OFF
	High	Floating	Other
		Present	Laser bias and modulation signal output

X = Don’t care

Other = Less than +7.5dBm (peak)

High = Logic high level, Low = logic low level

Floating = No Data Input, Present = Data Input,

OFF = Optical Power is less than –45dBm
