Optical DFB Laser

 

DFB Laser

Optical DFB Laser Plug-in modules.

Key Features:

– Selected wavelength according to ITU-T Grid, C-band, L-band and O-band available

– High optical output power up to 20mW for C-band & L-band, up to 16 mW for O-band

– High side mode suppression ratio (SMSR)

– 50GHz spacing available

– Narrow linewidth (down to 1 MHz) available

 

APEX Technologies’ DFB laser source modules provide 3 series (AP3390A, AP3392A and AP3395A), covering the ITU grid for all C-band, L-band and O-band, respectively. The AP3390 DFB laser source modules, integrated in the AP1000 Multi-test platform offer long-term power and wavelength stability, as well as precise tunability. Wavelengths on different grids (100GHz, 50GHz channels) are available on request. They are ideal tools for high frequency analog transmission in wideband wireless communications and long haul DWDM applications with external intensity modulator.

Connected with the polarization maintaining fiber pigtail, the AP3390A and AP3392A DFB lasers enable to directly connect a modulator without polarization control. The polarization state of output laser beam is maintained to a consistent orientation.
