In-Line Fiber Optic Polarizers 850nm
Introduce
In-Line Fiber Optic Polarizers 850nm 840nm 830nm these devices are used to block orthogonally polarized light from unpolarized (or randomly polarized) light sources using linear polarization. They attenuate orthogonally polarized light and have a high extinction ratio, the specific value depending on the specifications of each polarizer. They can also be used to enhance the extinction ratio of polarized signals. They are commonly used in fiber optic networks and measurement applications, including polarization analysis, polarization monitoring and control, polarization mode dispersion (PMD) monitoring, and improving polarization extinction ratio (PER). They are also ideally suited for use in polarization-maintaining fiber amplifiers, fiber lasers, and high-speed communication systems and instrumentation applications. We offer matching PM patch cords for use with these devices.
