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.

Gewei guarantees that every coupler complies with industry standards and delivers constant performance through the use of cutting-edge technology and premium materials. The Polarization Maintaining Filter Coupler from Gewei is the dependable solution for all of your fiber optic requirements, whether they relate to telecommunications, medical technology, or industrial uses.

Product Features

Low Insertion Loss: The 1x2 2x2 2000nm Polarization Maintaining Filter Coupler offers a low insertion loss of 0.3dB. It is designed with low-loss polarization maintaining fibers and optimized coupling ratios to minimize power loss and minimal signal attenuation.

High Return Loss: This coupler provides a high return loss of at least 50dB.

High Extinction Ratio: The 1x2 2x2 2000nm Polarization Maintaining Filter Coupler has a high extinction ratio it can effectively separate the polarizations of the input signal.

Wide Operating Wavelength Range

Compact Size: The coupler is designed to be compact and lightweight, providing significant benefits in terms of space utilization, cost-effectiveness, and ease of installation and maintenance.

Specifications
