1x2 2x2 2000nm Polarization Maintaining Filter Coupler

The 1x2 2x2 2000nm Polarization Maintaining Filter Coupler is a device that combines or splits the light signal with a specific wavelength of 2000nm in a polarization maintaining fiber. The 1x2 coupler has one input and two outputs, while the 2x2 coupler has two inputs and two outputs. This coupler utilizes polarization-maintaining fiber and allows for low insertion loss, high extinction ratio, and high return loss. The polarization maintaining feature ensures stable output and excellent polarization extinction ratio. This device is ideal for use in fiber optic communication systems, fiber sensors, and other fiber optic applications.

OPTICO proudly introduces the PM2000 FBT Coupler, a high-performance polarization-maintaining (PM) fiber component designed to operate at the 2000nm wavelength. Built on cutting-edge fused biconical taper (FBT) technology, this coupler ensures precise signal splitting while maintaining the polarization state, making it an indispensable component in demanding optical systems.

With its exceptional low insertion loss, high extinction ratio, and superior thermal stability, the PM2000 FBT Coupler is ideal for applications requiring accurate and reliable signal transmission. OPTICO's rigorous quality control and customizable features ensure our products meet the diverse and exacting needs of advanced optical systems.
