Notes:
1. Class 1 Laser Safety per FDA/CDRH, and EN (IEC) 60825 laser safety standards.
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. TWDP is calculated with a 1.0 equalizer and a 6,860 MHz Gaussian filter for the fiber simulation.
Jitter values at γ
T
and γ
R
are controlled by TWDP and stress receiver sensitivity.
5. If measured with TJ-free data input signal. In actual application, output TJ will be given by:
