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.
Note 5: CPR implements measurement according to IEEE 802.3 z 38.6.10 and EIA/TIA-526-14A.
Note 6: P is the turning point defined in IEEE 802.3 z 38.2.1.
Note 7: The receiver sensitivity is sampled in the center of an eye pattern and measured in the worst deterioration of the
extinction ratio.
Note8: Receiver 3 dB bandwidth is measured according to the indices listed in IEEE 802.3 z 38.6.11.
Note 9: The RL is the minimum loss of the received optical power reflected to the optical fiber.
