Notes:
1. The maximum Optical Output Power complies with the IEEE 802.3z specification, and is Class 1 laser eye safe.
2. Optical Extinction Ratio is defined as the ratio of the average output optical power of the transmitter in the high (“1”) state to the low (“0”) state. The
3. These are unfiltered 20-80% values.
4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 1). The characteristics include rise time, fall time, pulse
5. CPR is measured in accordance with EIA/TIA-526-14A as referenced in 802.3z, section 38.6.10.
6. TP refers to the compliance point specified in 802.3z, section 38.2.1.
7. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
8. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The conformance test signal is
9. The stressed receiver jitter is measured using the conformance test signal defined in 802.3z, section 38.6.11 and set to an average optical power 0.5
10. The 3 dB electrical bandwidth of the receiver is measured using the technique outlined in 802.3z, section 38.6.12.
11. Return loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.

are specified by the referenced Gigabit Ethernet eye diagram using the required filter. The output optical waveform complies with the requirements
of the eye mask discussed in section 38.6.5 and Fig. 38-2 of IEEE 802.3z.
