Optical Laser Source Products
Tunable laser sources, Fabry-Perot laser source modules, distributed feedback laser source modules

Keysight Laser Source Modules are available in various configurations for the best possible match to the most common applications.
Tunable lasers, in combination with optical power meters and a polarization controller, are used to measure the filter slope, isolation, polarization dependence, insertion loss and reflectivity of multiplexers/demultiplexers, channel interleavers and wavelength-selective switches used in reconfigurable optical fiber networks. The cascading of filter shapes from ROADMs (reconfigurable optical add-drop multiplexers) along the path of today's fast modulation-broadened signals makes it critical for component manufacturers to comply with nearly ideal channel specifications, leaving little to no room for measurement uncertainty. Keysight Laser Source Modules are available in various configurations for the best possible match to the most common applications.
