The polarization-maintaining isolator including 1030 1040 1050 1053 1060 1064nm 1310nm 1480nm 1550nm or others, it is a passive optical device that allows only one-way light to pass through. It uses panda polarization-maintaining fiber and maintains the input light polarization with a high extinction ratio. Polarization maintaining fiber isolators are usually used to protect lasers or amplifiers from back-reflected light. Unifiber provides single stage and dual stage isolator with different isolation levels to meet customer parameter requirements for different scenarios through different cost performance. In addition, it also provides customized services for high-power products.
