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 0 to 70 °C. The Transmitter Center Wavelength “X” is as specified by the
customer. The current available wavelengths are: 1470, 1490, 1510, 1530, 1550, 1570, 1590, and 1610
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. Pin represents the range of input powers where BER<10-12. Pin is valid over all data rates specified in
Section IV.
