The 1623 ITU G.695 compliant O-Band DWDM forward path DFB laser
components are designed for both broadcast and narrowcast analog applications.
The highly linear, OC-48 pinout compatible components feature options for up to
14 dBm of minimum optical output power with superior distortion performance
over an enhanced temperature range of -40C to +85C.

Absolute Maximum Ratings
Stresses in excess of the absolute maximum ratings can cause permanent damage to the device. These are absolute
stress ratings only. Functional operation of the device is not implied at these or any other conditions in excess of those
given in the operational sections of the data sheet. Exposure to absolute maximum ratings for extended periods can
adversely affect device reliability.

(1) Center Wavelength is temperature tuned to be within specs.
In order to prevent reflection-induced distortion, the laser must be connected to an optical cable having a return loff of at
least 55 dB for discrete reflections and 30 dB for distributed reflections.
