Optical circulator is a special fiber optic device that is capable of separating optical power traveling in opposite directions in one optical fiber. It can be used to achieve bi-directional transmission over a single fiber. Because of its high isolation between the input and reflected optical power and its low insertion loss, optical circulator is widely used in advanced communication systems and fiber-optical sensor systems. provides three-port or four-port optical circulators, covering standard 1310nm or 1550nm windows, or wider wavelength range from S band to L band. Special wavelength circulators, such as at 1030nm, 1040nm, 1050nm, are also available as customized products.

The standard power handling of this circulator is 300mW (CW). 500mW, 1000mW, 2000mW (CW) power handling circulators are also available. Please choose from the drop down menu at the option section.
