Note 1) “APC” represents operating LD by a constant monitor current for Pf=2mW at Tc=25°C.
Note 2) Modulation current for LD driver shall be less than this “Imod” when the optical extinction ratio is
set around 10dB.
Note 3) 2.48832Gb/s NRZ, 223-1, Pf_ave=1mW, Ibias=Ith, optical return loss from the line should be
greater than 24dB in order to ensure the specified performance.
Note 4) Guaranteed only when the length of LD pins are shorter than 5mm.
Note 5) Er=max|10×log(Pf / Pf@25°C)|
