Note 1) 2.48832Gb/s NRZ, 223-1, Pf_ave=5mW, Extinction ratio 10dB, optical return loss of the connectors should
be greater than 40dB in order to ensure the specified performance.
Note 2) See Table 1.
Note 3) Er=max|10´log(Pf / Pf@25°C)|
Note 4) Variation of the differential efficiency from the straight line between 1mW and 10mW.
