note 3 : Tolerable broadband noise on the power rail is under 50mVpp with frequency range of 50Hz to 1MHz.

note 4 : Internally, AC coupled with 50

Ω termination.

note 5 : If transmitter is used at more than 1.25Gb/s bit rate, Clocked-mode must be selected.

note 6 : Back face voltage is measured with a GND reference and normalized at the beginning of life relative to

the initial optical output power.

For example, a 50% drift in output power correlates to a 50% variation on the detected back face voltage.
