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. Applicable for rate selectable version only in low bandwidth mode.
4. 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.
5. Measured with DJ-free data input signal. In actual application, output DJ will be the sum of input DJ
and DJ.
