Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations. 2. Meets curve in FC-PI-4 Rev 8.00 Figure 21, which allows 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 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 Δ DJ. 6. Measured with conformance signals defined in FC-PI-4 Rev 8.00 specifications. 7. Measured with PRBS 27-1 at 10-12 BER
