The maximum Optical Output Power complies with IEEE 802.3 specification, and is class 1 laser eye safe.
These are unfiltered 20-80% values.
An eye diagram (Figure 9) specifies laser transmitter pulse response characteristics. The characteristics include rise time, fall time, pulse
undershoot, and ringing, all of which are controlled to prevent excessive degradation of the receiver sensitivity. The referenced Gigabit Eth-
ernet eye diagram using the required filter specifies these parameters. The output optical waveform complies with the requirements of the
eye mask discussed in section 38.6.5 and Fig. 38-2 of IEEE 802.3.
TP refers to the compliance point specified in 802.3, section 38.2.1.
The receiver sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
For a 2
The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3, section 38.6.11. The conformance test signal
is conditioned by applying deterministic jitter and intersymbol interference.
The stressed receiver jitter is measured using the conformance test signal defined in 802.3, section 38.6.11 and set to an average optical
power 0.5 dB greater than the specified stressed receiver sensitivity.
In order to meet the 10 km link power budget the transmitter can trade off spectral width and center wavelength as shown in Figure 10.

-1 PRBS the receiver will provide output data with better than or equal to 1E-12 BER.
