Optical Light Sources

Light sources simulate the optical voice, video and data signals of real-life service applications, which is why they are used in various types of tests.  Light sources come in a broad range of products that cater to various testing requirements: singlemode or multimode, polarized or non-polarized, broadband or narrowband, tunable, ITU-wavelength-centered and much more.

EXFO offers a broad range of light sources available in benchtop or modular formats, with both laser and LED light emission.  EXFO's WDM Laser Source is designed for multiwavelength network simulations, multiple and simultaneous inputs for EDFA characterization, as well as insertion loss measurement of WDM passive components.

FiberLabs’ ASE (Amplified Spontaneous Emission) light sources are white light sources with high-brightness over a broad spectral range. FiberLabs is a pioneer in developing and delivering ASE light sources in new spectral ranges in telecom and other bands. These light sources are widely used in applications such as characterization of WDM components, optical sensing and other optical measurements.
