1. Above specifications are for devices without connectors.
2. For a device with connectors, IL will be specified 0.3 dB higher, RL will be 5dB lower and ER will be 2dB lower.
3. The PM fiber and the connector key are aligned to the slow axis.
Research and Development
In-line fiber polarizers are created in order to pass linearly polarized light while blocking the orthogonal polarization from an unpolarized light source.
In-line fiber polarizers can be used for various fiber optic network applications. These would include polarization-maintaining fiber amplifiers, high-speed communication systems, fiber lasers and instrumentation.
