Optical Fiber Circulator
- A special fiber-optic component
- Used to separate optical signals
- Non-reciprocal optics
- Cheap but high quality
PRODUCT DESCRIPTION
Optical circulators are non-reciprocal optics, which means that changes inthe properties of light passing through the device are not reversed when thelight passes through in the opposite direction. This can only happen when thesymmetry of the system is broken, for example by an external magnetic field.
