1623A/B O-Band DWDM DFB Laser Module
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
-40°C to +85°C.

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) Distortion performance assumes 0km dispersion. 3.2% OMI, 110 ch. NTSC
In order to prevent reflection-induced distortion, the laser must be connected to an optical cable having a return loss of at
least 55 dB for discrete reflections and 30 dB for distributed reflections.
