Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. High Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
3. Low Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
4. Also specified to meet curves in FC-PI-2 Rev 10.0 Figures 18, 19, and 20, which allow trade-off
between wavelength, spectral width and OMA.
5. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
6. Unfiltered, 20-80%. Complies with FC 4x eye mask when filtered.
7. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
8. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and DJ.

9. Applicable for Rate Selectable version only in low bandwidth mode.
10. Measured with conformance signals defined in FC-PI-2 Rev. 10.0 specifications. Value in OMA.
