Frequently Asked Questions

The Ultra-stable PM Fiber Patch Cable is a polarization-maintaining single-mode fiber patch cable developed by CSRayzer, designed for ultra-high extinction ratio, low loss, and high power to ensure stable polarization direction during transmission of polarized light signals.

The key features include a selectable cutoff wavelength from 350-2000 nm, low loss, high extinction ratio output, and high withstand power options.

The cable is suitable for applications in quantum computing, cold atom systems, quantum precision measurement, and quantum communication.

CSRayzer offers customization services for any wavelength between 350-2000 nm and any cable length.

The available connector options are FC/APC or FC/PC.

The typical insertion loss ranges from 0.5 dB to 1 dB, depending on the wavelength range.

The polarization extinction ratio for the ultra-stable version is 23 to 25 dB, depending on the wavelength range.
