High Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
Low Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
Also specifi ed to meet curves in FC-PI-4 Rev 7.00 (“Fibre Channel Physical Interface-4 Specifi cation”. American National
Standard for Information Systems, September 20, 2007) Figures 21, 22, and 23, which allow trade- off between wavelength,
spectral width and OMA.
Equivalent extinction ratio specifi cation for Fibre Channel. Allows smaller ER at higher average power.
For 8.5 Gb/s operation, Jitter values for gamma T and gamma R are controlled by TDP and stressed receiver sensitivity.
Unfi ltered, 20-80%. Complies with IEEE 802.3 (Gig. E), FC 1x and 2x eye masks when fi ltered.
Measured with conformance signals defi ned in FC-PI-4 Rev. 10.0 specifi cations. Value in OMA. Measured with PRBS 2
