Customized Details

L-Band(1565~1625) Single/Dual Stage Steel Tube Type SMF-28e Polarization Insensitive Optical Isolator, Standard Size, P Grade

A Polarization Insensitive Optical Isolator is an optical device that permits light to pass in one direction while blocking any back-reflection or backscattered light, regardless of the polarization state of the incoming light. This insensitivity to polarization ensures consistent performance across various optical systems, making it crucial for maintaining signal integrity and stability in optical communication networks, laser systems, and optical amplifiers, where preventing interference and feedback is essential.
