Notes:
1. 10GFC 1200-MX-SN-I/ IEEE 802.3ae 10GBASE-SR compliant
2. These parameters are interrelated: see IEEE 802.3ae, Clause 52.
3. For information only
4. Trade-offs are available between spectral width, center wavelength and minimum Optical Modulation Amplitude (OMA). See Figure 4A and
Optical Modulation Table.
5. The maximum 10GBASE-SR Average Optical Output Power shall be the lesser of the class 1 safety limit as defined by IEEE 802.3ae 52.10.2 or
the average receive power maximum defined by IEEE 802.3ae Table 52-9
