Product Details
Polarization Maintaining Fiber Optical Isolator Dual Stage 900um
Description of Polarization Maintaining PM Optical Isolator Single
Stage or Dual Stage
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. Unifiber
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.
