Notes:
1. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
3. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when filtered.
4. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and DJ.

5. Measured with conformance signals defined in FC-PI 13.0 specifications.
6. Measured with PRBS 2
