Notes:
1. High Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
2. Low Bandwidth Mode. Class 1 Laser Safety per FDA/CDRH and EN (IEC) 60825 regulations.
3. Over case temperature of -5 to 75 °C. The Transmitter Center Wavelength “X” is as specified by the
customer. The current available wavelengths are: 1471, 1491, 1511, 1531, 1551, 1571, 1591, and 1611
nm. Please see the “Product Selection” section on page 2.
4. Equivalent extinction ration specification for Fibre Channel. Allows smaller ER at higher average
power
5. Unfiltered, 20-80% measured w/ a “00001111” pattern. Complies with FC 4x eye mask when filtered.
6. Unfiltered, 20-80% measured w/ a “00001111” pattern. Complies with IEEE 802.3 (Gig. E), FC 1x
and 2x eye masks when filtered.
7. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and DJ.
8. Measured with conformance signals defined in FC-PI-2 Rev. 10.0 specifications. Value in OMA.
Measured with PRBS 2⁷-1 at 10^-12 BER.
9. Represents sensitivity at minimum Extinction Ratio with rate select high. Measured with PRBS 27-1 at 10-12 BER.
