1064/1550 nm Polarization Maintaining Filter

Overview

The FT-92 is a polarization maintaining WDM filter that multiplexes or demultiplexes 1064 nm and 1550 nm light in a single compact device. Built entirely on polarization maintaining fiber, it keeps the polarization state stable through both wavelength paths, which matters for 1064 nm fiber lasers, coherent systems and sensing setups where polarization drift degrades performance. Two configurations are offered: 1064 nm pass with 1550 nm reflect, or 1550 nm pass with 1064 nm reflect, covering the 1020–1080 nm and 1520–1580 nm bands. It provides 20 dB minimum extinction ratio, 50 dB return loss and CW power handling options up to 20 W.
