Circulator
Neptec’s Polarization Insensitive Optical Circulator is a non-reciprocal device that routes incoming signals from any port to the next. An optical circulator transmits the signal from port 1 to port 2, while simultaneously transmitting signal from port 2 to port 3. Neptec’s optical circulators are used in advanced communication systems like DWDM and bi-directional pumps.
Every network is different. Neptec ensures that every product we sell is highly customizable to fit any optical fiber application. If the standard circulator below do not fit your application, we would be glad to review your specifications and quote a custom circulator for you.
