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.
