FOCI's Polarization Independent Circulators are ultra reliable devices featuring high isolation, low insertion loss, low cross talk, and low PDL over wide ranges of temperature and wavelengths. The Polarization Independent Circulators are designed to transmit signal from port 1 to 2, and from port 2 to port 3. While completely isolating port 1 and port 3 from each other. With its innovative isolation and exceptional low insertion loss for all applications demanding critical performance. Featuring PDL, PMD, and other optical characteristics, the M-CN series are the best quality circulators available. These highly reliable circulators are fabricated using exceptional laser welding technology. Various types of pigtailing and connector termination are available to meet your requirements.
