470nm 3-port Polarization Insensitive Optical Circulator
          470nm TGG 3-port Polarization Insensitive 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 Quantum Communication, 
Fiber Laser and Coherent Detecting field. If need higher power version please tell us to confirm.
