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