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 transmitter is driven with a Gigabit Ethernet 1250 MBd 8B/10B encoded serial data pattern. This Optical
Extinction Ratio is expressed in decibels (dB) by the relationship 10log(Phigh avg/Plow avg).
3. These are unfiltered 20-80% values.
4. Laser transmitter pulse response characteristics are specified by an eye diagram (Figure 2). The characteristics include rise time,
fall time, pulse overshoot, pulse undershoot, and ringing, all of which are controlled to prevent excessive degradation of the
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 discussed in section 38.6.5 and Fig. 38-2 of
IEEE 802.3z.
5. TP refers to the compliance point specified in 802.3z, section 38.2.1.
6. The receive sensitivity is measured using a worst case extinction ratio penalty while sampling at the center of the eye.
7. The stressed receiver sensitivity is measured using the conformance test signal defined in 802.3z, section 38.6.11. The
conformance test signal is conditioned by applying deterministic jitter and intersymbol interference.
8. 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 dB greater than the specified stressed receive sensitivity.
9. The 3 dB electrical bandwidth of the receiver is measured using the technique outlined in 802.3z, section 38.6.12.
10. Return loss is defined as the minimum attenuation (dB) of received optical power for energy reflected back into the optical fiber.
