tudes relative to the logical 1 and 0 levels. This is measured through a 4th order Bessel -Thompson filter with 0.75 * Data Rate 3-dB bandwidth
and corrected to the full bandwidth value. Use of the 4G FC compliance filter results in an equivalent rise/fall time specification of 116 ps.
Modulation Amplitude is defined in terms of average optical power (P
1)/(ER+1)). In this expression, the extinction ratio, the ratio of the average optical power (in μW) in a logic level one to the average optical power in
a logic level zero measured under fully modulated conditions in the presence of worst case reflections, must be the absolute (unit less linear) ratio
and not expressed in dB. The specified Optical Modulation Amplitude is equivalent to an average power of -7.3 dBm at an extinction ratio of 9 dB.
