Ultra-stable PM Fiber Patch Cable
Product introduction
The ultra-stable polarization-maintaining single-mode fiber patch cable developed by CSRayzer is specially designed. Compared with the conventional polarization-maintaining fiber patch cable, it has the characteristics of ultra-high extinction ratio, low loss and high power, which ensures that the polarization direction of polarization state will not change when transmitting polarized light signals. Each polarization-maintaining patch cable is tested separately at the alignment wavelength to ensure the polarization extinction ratio and loss at the optical fiber connection, which is widely used in optical path systems with extremely high polarization state requirements, such as quantum calculation and quantum precision measurement systems. CSRayzer provides a variety of customization services for polarization-maintaining single-mode patch cable, such as any wavelength between 350-2000nm and any length.
