PM optical fiber connector
With the increasing application in the fields of aerospace, unpiloted, industrial manufacturing and communication, the application of the Polarization-Maintaining PM patch cord as a representative special product will usher in a larger market demand. In order to cope with the market development, HYC independently designed and developed a new type of PM connector with 360° ferrule adjustable, the PM angle can be controlled at ±1°, leading above the industry level. It also features high precision, low loss, and ultra-high extinction ratio, and is widely used in instruments or scenes that are sensitive to polarization.
