PINOUT
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 –12dBm
average power
RMS input referred optical noise equivalent power is
obtained by measuring the RMS output noise into a 1875
MHz, 4-pole Bessel-Thompson filter then dividing by the
responsivity. A scaling factor of 14 is used to predict a BER
of 10
Sensitivity is measured with an optical source with an
extinction ratio of 3dB.
Stressed receiver sensitivity is measured with 3.5dB
vertical eye closure (intersymbol interference) and with
0.3UI of jitter added. The measurement technique is
defined in IEEE 802.3ae.
