1. The average output optical power is compliant with IEC 60825-1 Amendment 2, Class 1M Accessible Emission Limits.
2. Informative. Corresponds to POUT = -8 dBm and ER = 6 dB.
3. Spectral width is measured as defined in EIA/TIA-455-127 Spectral Characterization of Multimode Laser Diodes.
4. Total jitter is TP2 - TP1 as defined in IEEE 802.3 clause 38.6 (Gigabit Ethernet).
5. Deterministic jitter is informative. Combined random and deterministic jitter should be no higher than stated total jitter.
6. Channel skew is defined for the condition of equal amplitude, zero ps skew signals applied to the transmitter inputs.
7. Differential input voltage is defined as the peak to peak value of the differential voltage between DIN+ and DIN-. Data inputs are CML
compatible.
8. Differential input impedance is measured between DIN+ and DIN-.
