Notes:
11. The maximum Optical Output Power complies with IEEE 802.3 and is Class 1 laser eye safe.
12. Optical Extinction Ratio is defined as the ratio of the average optical power of the transmitter in the high (“1”) state to the low (“0”) state. The
13. Optical Rise and Fall Times are 20-80% value. Laser transmitter pulse characteristics are typically specified by an eye diagram - see Figure 6. The
14. CPR is measured in accordance with EIA/TIA-526-14A as referenced in IEEE 802.3 section 38.6.10.
15. Measured at TP2. TP refers to the compliance point specified by IEEE 802.3, section 38.2.1.

transmitter is driven with a Gigabit Ethernet 1250 MBd 8b/10b encoded serial data pattern. Optical Extinction Ratio is expressed in decibels (dB) by
the relationship 10log(P
characteristics include rise time, fall time, pulse overshoot, pulse undershoot and ringing, all of which are controlled to prevent excessive
degradation of receiver sensitivity. These parameters 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 described in IEEE 802.3 section 38.6.10 and Figure 38-2.
