Product Description
Dual Stage TGG Polarization Maintaining Optical Isolator 780–1080nm PM Panda Fiber Isolator
Product Overview
GEZHI Photonics manufactures high-performance dual stage TGG-based PM optical isolator covering 780nm, 808nm, 850nm, 880nm, 980nm, 1030nm, 1064nm and 1080nm. This two-port micro-optic component adopts PM panda fiber design, allowing unidirectional light transmission while blocking back reflection and backscattering effectively.
Our PM dual stage isolator delivers ultra-low insertion loss, high isolation, high extinction ratio and stable long-term performance, widely deployed in fiber lasers, fiber amplifiers, optical test instruments, CATV fiber links and telecom fiber LAN systems. Custom wavelength, fiber type, connector and power rating are supported for CW & pulse laser applications.
