1x2 2x2 1310nm 1550nm Polarization Maintaining Filter Coupler

OPTICO offers premium-quality PM Fiber FBT Couplers specifically designed for demanding polarization-maintaining fiber applications. Operating at key wavelengths such as 1060nm, 1310nm, and 1550nm, these couplers ensure efficient signal splitting while maintaining the polarization state of transmitted light. This makes them ideal for applications requiring exceptional stability and precision.

The OPTICO PM FBT Coupler is based on fused biconical taper (FBT) technology, allowing for the highest levels of customization in terms of coupling ratios, package types, and polarization-maintaining requirements. These couplers are built with meticulous attention to detail to meet the strictest quality standards.

The 1x2 2x2 1310nm 1550nm Polarization Maintaining Filter Coupler is an optical component that combines or splits two input optical signals into one or two output optical signals based on the polarization state of the input signals. It operates at two wavelengths, 1310nm and 1550nm, and maintains the polarization of the light during the coupling process. The component includes a filter that blocks unwanted wavelengths and noise. The numbers "1x2" and "2x2" indicate the number of input and output ports of the component.

With advanced technology and high-quality materials, OPTICO ensures that each coupler meets industry standards and performs consistently. Whether it's for telecommunications, medical equipment, or industrial applications, OPTICO's Polarization Maintaining Filter Coupler is the reliable choice for your fiber optic needs.

* Above specifications are for devices without the connectors.

* For devices with connectors, IL will be 0.3dB higher, RL will be 5dB lower, and ER will be 2dB lower.

*The PM fiber and the connector key are aligned to the slow axis. And for F type, fast axis is blocked.
