Polarization Maintaining In-Line Polarizer, 1310/1550nm

A Polarization Maintaining (PM) In-Line Polarizer is an optical device designed to ensure that only light with a specific polarization state is transmitted through a fiber optic system. It filters out unwanted polarization states, allowing only the desired polarization to pass, thus maintaining consistent polarization in the output light. Integrated with PM fibers, this device preserves the polarization during transmission, reducing cross-talk and drift. Its compact in-line design allows easy integration into existing systems. PM In-Line Polarizers are crucial in applications requiring stable polarization, such as interferometers, fiber optic sensors, and polarization-sensitive communication systems.
