980nm Polarization Maintaining 1x2 Filter Coupler
The 980nm Polarization Maintaining 1x2 Filter Coupler uses thin-film filter technology to split or combine optical power at a specified coupling ratio while preserving the linear polarization state of the input light. Designed with PM980 fiber, it provides low insertion loss, a high extinction ratio, low back reflection, and stable performance in polarization-sensitive optical systems. Standard coupling ratios from 50/50 to 5/95 are available, with custom ratios and optical power options up to 10W. Supporting both-axis operation, the coupler is suitable for fiber lasers, optical amplifiers, fiber sensors, fiber optic gyroscopes, and PM optical networks. Coupling ratio, power handling, pigtail length, fiber diameter, and connector type can be customized, with the slow axis aligned to the connector key by default.
