P R is the average optical power at the fiber face.
P R,OMA is the peak to peak optical power at the fiber face
(Optical Modulation Amplitude)
where ER is the extinction ratio (linear) of the optical
source.
Bandwidth and Low Frequency Cutoff are measured with
a small signal sinusoidal light source with –10dBm
average power
Sensitivity is measured with an optical source with an
extinction ratio of 3dB. For sensitivity measurements at 2
and 4Gbps, bandwidth limiting of the TIA is assumed to
be implemented at the front end of the post amplifier.
Rise/Fall times are corrected for optical source Rise/Fall

Value shown is with no external power supply filtering.
Group delay is a sensitive measurement to package
interface, and includes the effects of PD, TIA and package.
Measurement is made with TO leads as short as possible.
DJ TIA is specified as contributed DJ by the TIA, obtained
from
RJ TIA is specified as contributed DJ by the TIA, obtained
from RJ 2

TO can and the circuit board. AOC cannot guarantee all
performance specifications for parts without the flex
