7 / 13 page 7 Receiver Optical Characteristics (TA = 0°C to +70°C, VCC = 3.14 V to 3.47 V) Parameter Symbol Min. Typ. Max. Unit Reference Input Optical Power PIN –17 0 dBm avg. 7 Stressed Receiver Sensitivity 62.5 µm –12.5 dBm avg. 8 50 µm –13.5 dBm avg. 8 Stressed Receiver Eye 201 ps 6, 9 Opening at TP4 Receive Electrical 3 dB 1500 MHz 10 Upper Cutoff Frequency Operating Center Wavelength λC 770 860 nm Return Loss 12 dB 11 Signal Detect – Asserted PA –17 dBm avg. 12 Signal Detect – Deasserted PD –30 dBm avg. 12 Signal Detect – Hysteresis PA – PD 1.5 dB 12 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 optical power of the transmitter in the high (“1”) state to the low (“0”) state. Ex- tinction Ratio shall be measured using the methods specified in TIA/EIA.526.4A. This measurement may be made with the node transmitting a 36A.3 data pattern. The Saturation Ratio is measured under fully modulated conditions with worst case reflections. A36A.3 data pattern is a repeating K28.7 data pattern, which generates a 125 mHz square wave. 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 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. 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 conditioned by applying deterministic jitter and intersymbol interference. 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 dB greater than the specified stressed receiver sensitivity. 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. 12. With valid 8B/10B encoded data.
