Note 1: The Slope efficiency drop is the slope efficiency will be decreased with the temperature increasing.

Note 2: The center wavelength and Side-mode suppression ratio should be tested under modulated conditions using 1.25Gbps, PRBS331-1, ER=9dB. optical power should between 0.6dBm to 4dBm.

Note 3: RIN12OMA is the ratio of noise to modulated optical signal in the presence of a back reflection.

Where:

RINxOMA=Relative Intensity Noise referred to optical modulation amplitude measured with x dB reflection,

PN=Electrical noise power in Watts with modulation off,

PM=Electrical power in Watts with modulation on,

BW=Low pass bandwidth of apparatus-high pass bandwidth of apparatus due to DC blocking capacitor [noise bandwidth of the measuring system(Hz)].

Note 4: Tracking Error ( A is Typical AOP ):

Note 5: Linearity is calculated by first determining slope between several sequential pair of points on power/current curve Lh= (max(h1, h2 .....hi) - min(h1, h2.....hi))/ have , hi = Ipd / Pin (Pin=-30~0dBm).
