The polarization-maintaining isolator uses panda polarization-maintaining fiber and maintains the input light polarization with a high extinction ratio, it is a passive optical device that allows only one-way light to pass through. OPTEKCOM provides single stage and dual stage isolator with different wavelength including 1030nm 1040nm 1050nm 1053nm 1060nm 1064nm 1310nm 1480nm 1550nm or others, it usually used to protect lasers or amplifiers from back-reflected light.
