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 -40 to 85 °C. The Transmitter Center Wavelength “X” is as specified,
including 1471, 1491, 1511, 1531, 1551, 1571, 1591, and 1611 nm. Please see the “Product Selection”
section on page 1.
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. 60kms represents 1200ps/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.
