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.

(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.
