Product Description

632nm In-line Polarizer with High Transmission Efficiency

 

Product Description

Kerns Tech's in-line fiber polarizers are designed to pass linearly polarized light while blocking the orthogonal polarization from an unpolarized (or randomly polarized) light source. They can attenuate the orthogonally polarized light with a high extinction ratio of at least 23 dB, depending on the specifics of each polarizer (see the tables below). These polarizers can also be used to enhance the extinction ratio of polarized signals. For the PM versions of these devices, the output polarization and 2.0 mm narrow key of the connector are aligned to the slow axis of the fiber. For FC/APC-terminated versions, the return loss will be higher than for FC/PC-terminated versions because the angled ferrule minimizes back reflections.

Fiber Core Alignment

Note that the minimum attenuation for these devices depends on excellent core-to-core alignment when the connectors are mated. This is crucial for shorter wavelengths with smaller fiber core diameters that can increase the loss of many decibels above the specification if they are not perfectly aligned. Different vendors' connectors may not mate well with each other, especially for angled APC.

Fiber Cleanliness
Fibers with smaller core diameters (<5 μm) must be kept extremely clean, contamination at fiber-fiber interfaces, combined with the high optical power density, can lead to significant optical damage. This type of damage usually requires re-polishing or replacement of the connector.

Maximum Optical Input Power

Due to their small fiber core diameters for short wavelength and high photon energies, the damage thresholds for device is substantially reduced than the common 1550nm fiber. To avoid damage to the exposed fiber end faces and internal components, the optical input power should never exceed 20 mW for wavelengths shorter 650nm. We produce a special version to increase the how handling by expanding the core side at the fiber ends
