Notes:
1. Parameters are specified over temperature and voltage, at end of life unless otherwise noted.
2. Class 1 Laser Safety per FDA/CDRH and IEC-825-1 regulations.
3. Over case temperature of -10 to 85 °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 1. It is possible to offer wavelength range
(X+5) nm to (X-7) nm. Please contact Finisar sales team for this if needed.
4. Full width, -20dB from peak.
5. Measured filtered, at 2.488 Gb/s. Min represents worst-case ER over temperature and at end of life.
6. Unfiltered, 20% to 80%.
7. Measured per GR-253² section 5.6 for OC-48 B.
8. SMF-28 fiber used. 50kms represents 1000ps/nm at 1610nm. Measured at 2.488Gb/s with a PRBS
2²³-1 pattern at a BER<10^-12.
9. P_in represents the range of input powers where BER<10^-12. P_in is valid over all data rates specified in
Section VI.
