In-Line Fiber Optic Depolarizers A range of Lyot type all-fiber depolarizers applicable to Raman, ASE, SLD, ELED and Fabry-Perot sources FEATURES: Low residual extinction ratio All-fiber configuration Large operating bandwidth Low Loss OEM packaging available APPLICATIONS: Raman pump laser sources ASE, SLD, ELED and Fabry-Perot laser sources C, L and S-band Optical transmission systems Optical fiber sensors Randomize residual polarization for low coherence sources A range of Lyot type all-fiber depolarizers which can be matched to a wide range of sources. Lyot depolarizers produce randomly polarized light and can achieve a very high level of performance. This type of depolarizer is specifically designed for applications in which the level of residual polarization is critical to system performance. Each model shown in the specification table overleaf is matched to a specific source by relation to the narrowest line width of the source, allowing the cost / performance balance to be managed according to the desired Degree of Depolarization (DOP) for your application. The depolarizers can be custom designed to meet a range of performance specifications and can be tailored to the customers requirements. Please contact our technical design team to discuss specific requirements.
