Fiber Optic Circulator


Fiber Optic Circulator is a multiport optical device that allows light to transmit in only one direction from port 1 to port 2, then from port 2 to port 3. The light is blocked at the opposite direction.

Fiber Optic Circulator is widely used in communication systems as add-drop multiplexer, bi-directional pump, and chromatic dispersion compensation device.

Fiberwe manufactures 3-port, 4-port, 6-port single mode (SM) fiber optic circulator, and polarization-maintaining (PM) fiber optic circulator. Besides normal 1310 nm (O-Band), 1550 nm (C-Band), we also manufacture special wavelength fiber optic circulators such as 780 nm, 850 nm, 900 nm, 1064 nm, etc.

Both low power and high power fiber optic circulators are available.
