Notes:
1. Class 1 Laser Safety per FDA/CDRH and IEC-825-1 regulations.
2. Also specificied to meet curves in FC-PI-2 10.0 Figures 18 and 19, which allow trade-off between
wavelength, spectral width and OMA.
3. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average
power.
4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye mask when filtered.
5. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input
DJ and ∆DJ.
6. If measured with TJ-free data input signal. In actual application, output TJ will be given by:
