Product Introduction

The polarization-preserving thermal circulator of Shanghai Joinwit is fully applicable to the 

polarization state analyzer series JW8611/JW8610/JW8610M.

It can achieve precise and repeatable temperature cycling of the tested optical fiber.

This PER measurement system demonstrates excellent accuracy and repeatability.

Its ease of use and automated interface (such as the analog output port for active alignment) 

enable efficient and precise applications in production environments.
