Note 1.  TP refers to the compliance point specified in IEEE802.3z, section 38.2.1.
Note 2.  Optical transition time is the time interval required for the rising or falling edge of an optical pulse to transition
               between the 20% and 80% amplitudes relative to the logical 1 and 0 levels.
Note 3.  Measured with a PRBS 2⁷-1 test pattern, @1.25Gb/s, ER=9 dB, BER=10^-12.
