Product Profile
PM fiber fused couplers are typically manufactured using the fused biconical taper (FBT) technique, which involves fusing and tapering two optical fibers to create the coupling effect. They are commonly used in fiber optic gyroscopes, fiber optic sensors, and telecommunications systems.
The 2x2 1064nm Polarization Maintaining Coupler is an optical component that allows the splitting or combining of optical signals. Specifically, it has two inputs and two outputs, and it is designed to maintain the polarization state of the input signals. The operating wavelength of this coupler is 1064nm, which is commonly used in various laser applications.
Optico offers a range of high-quality polarization maintaining couplers for use in various fiber optic applications. These couplers are designed to split or combine optical signals while maintaining the polarization state of the light. With advanced manufacturing processes and rigorous quality control, Optico's polarization maintaining couplers are known for their excellent performance, durability, and low cost.
Product Features
High Extinction Ratio: With the use of polarization-maintaining fibers and a carefully designed coupling structure, the 2x2 1064nm Polarization Maintaining Coupler features a high extinction ratio of at least 20dB and can effectively separate and filter out unwanted light.
High Return Loss: The 2x2 1064nm Polarization Maintaining Coupler has undergone precise manufacturing processes and rigorous testing procedures to achieve a high return loss of 50dB, thus minimizing back reflections and other sources of signal degradation.
Low Cost: Compared to other couplers with similar features, this coupler is offered at a lower cost without sacrificing performance and quality.
