High Power 785nm PM 3-port Optical Circulator
      High Power 785nm Polarization Maintaining (PM) 3-port Optical Circulator is a fiber passive component built with TGG 
crystal, which can change signal light transmission path, the signal can be delivered from Port 1 to Port 2, the other signal 
light from Port 2 to Port 3, the high isolation can block the back reflection light. It's widely used in Laser System, Fiber Optic 
Sensor and Coherent Detecting field. If need pulse type please contact us to confirm.
