Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. Meets curve in FC-PI-4 Rev 8.00 Figure 21, which allows trade-off between wavelength, spectral
width and OMA.
3. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x eye mask when filtered.
5. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and
Δ DJ.
6. Measured with conformance signals defined in FC-PI-4 Rev 8.00 specifications.
7. Measured with PRBS 2
