RMS Spectral Width	λrms	-		3.5	nm	1
Average Launch Power, each lane	PAVG	-5	-0.5	+2.5	dBm
Optical Modulation Amplitude (OMA)	POMA	-5	-0.5	+2.5	dBm	1
Difference in Launch Power between any two lanes	Ptx,diff			5.0	dB
Launch Power in OMA minus Transmitter and Dispersion Penalty (TDP), each Lane	OMA-TDP	-2.3			dBm	1
Rise/Fall Time	Tr/Tf			30	ps
Extinction Ratio	ER	3.5			dB
Relative Intensity Noise	Rin			-128	dB/Hz
Optical Return Loss Tolerance	TOL			11.9	dB
Transmitter Reflectance	RT			-12	dB
Transmitter Eye Mask Margin	EMM	10			%	2
Average Launch Power OFF Transmitter, each Lane	Poff			-30	dBm
Transmitter Eye Mask Definition {X1, X2, X3, Y1, Y2, Y3}		{0.23, 0.34, 0.43, 0.26, 0.36, 0.4}

Parameter	Symbol	Min	Typical	Max	Unit	Notes
Receiver
Center Wavelength	λC	1290	1310	1330	nm
Damage Threshold	THd	+3			dBm
Overload, each lane	OVL	+2			dBm
Receiver Sensitivity in OMA, each Lane	SEN			-8.6	dBm	3
Signal Loss Assert Threshold	LOSA	-30			dBm
Signal Loss Deassert Threshold	LOSD			-15	dBm
LOS Hysteresis	LOSH	0.5		6	dB

Notes:
1. Transmitter wavelength, RMS spectral width and power need to meet the OMA minus TDP specs to guarantee link performance.
2. The eye diagram is tested with 1000 waveform.
3. Measured with conformance test signal at receiver input for BER = 1x10-12.
