General Specification Considerations (Notes):
1. IEEE 802.3ae Clause 52 compliant.
2. These parameters are interrelated: see IEEE 802.3ae, Clause 52.
3. See Table 9. Trade-offs are available among spectral width, center wavelength, and minimum optical modulation amplitude.
4. The 10GBASE-SR launch power shall be the lesser of the Class 1 safety limit as defined in IEEE 802.3ae 52.10.2 or the average receive power
maximum defined by IEEE 802.3ae -2002 Table 52-9.
5. The transceiver’s launch condition meets the requirement of 10 Gigabit Ethernet multimode fiber as detailed in TIA 492AAAC.
6. Vertical eye closure penalty and Stressed eye jitter are test conditions for Stressed sensitivity (OMA) measurements.
