Notes:
● 50/125µm fiber with NA = 0.2, 62.5/125µm fiber with NA = 0.275.
● Unfiltered, 20-80%. Complies with FC 1x and 2x eye mask when filtered.
● TWDP is calculated with a 1,0 equalizer and a 9.84 GHz Gaussian filter for the fiber simulation. Jitter values at γT and γR are controlled by TWDP and stress receiver sensitivity.
