Product Description

Polarization Sensitive Isolator
(GK-PSI Series)
Description

Polarization Sensitive Isolator (PSI Series) is designed for applications in fiber optic systems that require high isolation and minimal insertion loss. This isolator operates at a wavelength of 638 nm, providing excellent environmental stability and reliability. It is particularly suitable for applications that require precise polarization maintenance, such as in fiber lasers and amplifiers. The PSI series features high extinction ratio and the ability to handle high optical power, making it a multifunctional component in advanced optical systems.
Here are some key features of the PSI series:
Low insertion loss: The typical insertion loss is around 1.5 dB, ensuring efficient transmission of signals through isolators
High isolation: The minimum isolation reaches 23 dB, providing excellent isolation performance in different polarization states
High extinction ratio: With an extinction ratio of up to 20 dB, it ensures the purity of polarized light
High power processing capability: capable of handling continuous wave optical power up to 20 W, suitable for high-power applications
Excellent environmental stability: The working temperature range is 25 to 45 ºC, ensuring stable performance under different environmental conditions
Reliability: Made with high-quality materials to ensure long-term reliable performance
These characteristics make the PSI series polarization sensitive isolators highly suitable for fiber lasers, fiber amplifiers, and other high-performance optical systems that require precise polarization control. By precisely controlling the propagation direction and polarization state of light, PSI series isolators help improve the overall performance and reliability of the system.
