The PureSpectrum-LM from TeraXion is a Distributed Feedback (DFB) Laser Module that operates from 1525 to 1565 nm. It delivers a CW output power of up to 100 mW and has a linewidth of less than 1 MHz. The laser module has a side mode suppression ratio of above 30 dB and a polarization extinction ratio of above 17 dB. It has slow frequency tuning and fast frequency tuning features that can be controlled by a software command and through external modulation. The laser requires a DC supply of 9-36 V and consumes less than 4.5 W of power.
The PureSpectrum-LM is available in a package that measures 90 x 64 x 30 mm and has a PM Panda fiber, FC/APC (narrow key) optical connector, and a Hirose DF11-12DP-2DS connector. The laser module is suitable for LIDAR / remote sensing, laser-based metrology system, test & measurement / coherent OTDR, and perimeter detection in security applications.
