Note 8
Note 1: The maximum output optical power is in compliance with the IEEE 802.3 z Specifications; class-1 laser human
eye security is provided.
Note 2: Extinction ratio is the ratio of average output optical powers when the transmitter outputs "0" and inputs "1"
Note 3: 20%-80% without any filtering.
Note 4: The pulse effect characteristics of a laser may be provided in an eye pattern. Output waveform conforms to the
requirements for eye pattern templates in 38.6.5 in IEEE 802.3 z.
