Notes:

1. Class 1 Laser Safety per FDA/CDRH, and EN (IEC) 60825 laser safety standards.

2. Unfiltered, 20-80%. Complies with FC 1x and 2x eye mask when filtered.

3. TWDP is calculated with a 1,0 equalizer and a 6,860 MHz Gaussian filter for the fiber simulation. Jitter values at γ

and

are controlled by TWDP and stress receiver sensitivity.

4. If measured with TJ-free data input signal. In actual application, output TJ will be given by:
