    1.  Notes:

    2. 1. Class 1 Laser Safety.  

    3. 2. Also specified to meet curves in FC-PI-2 Rev. 10.0 Figure 18, which allow trade-off between wavelength, spectral width.

    4. 3. Equivalent extinction ratio specification for Fibre Channel. Allows smaller ER at higher average power.

    5. 4. Unfiltered, 20-80%. Complies with IEEE 802.3 (Gig. E) and FC 1x eye masks when filtered.

    6. 5. Measured with DJ-free data input signal .In actual application, output DJ will be the sum of input DJ and ΔDJ.

    7. 6. Measured with conformance signals defined in FC-PI-2 Rev. 10.0 specifications.  

    8. 7. Measured with PRBS 27-1 at 10-12 BER .
