3 port 1310 or 1550nm insertion loss optical circulator optical device communication systems
GEZHI Photonics 3port Optical Circulator is widely used in advanced communication systems and fiber-optical sensor systems. Circulator used to drop an optical channel from a DWDM system using a Fiber Bragg Grating.Circulator can be used to send optical signals through a single fiber in two directions.





Applications
2.reflected from the FBG then reenters the Circulator in Port 2 and is routed accordingly to Port 3
3.The remaining signals pass through the FBG and exit on the top fiber.
