An optical isolator is a device that ensures unidirectional transmission of light beams. Through micro-optical structural design, it prevents possible reflected light in the optical path from harming the light source. PM optical isolators connect PM fiber with a micro-optical system and are suitable for polarization-maintaining system applications. Our company provides various PM optical isolators to meet the needs of different application fields, such as single-polarization-state PM and dual-polarization-state PM, in-line isolators with PM fiber output at both ends, or pigtail-type optical isolators connected directly to the light source, etc. Some applications require higher isolation; our company provides dual-stage PM isolator series products to meet this demand. The wavelength of the PM optical isolators provided by our company can be selected from 500 nm to 1550 nm, thus meeting the requirements of various wavelength application systems.
