CIRM is designed for bi-directional transmission in optical fiber. It separate transmitting signals from Port 1 to Port 2, and directs receiving signal from Port 2 to Port 3.
The QAMnet CIRM fiber optic circulator is a compact, patented, high-performance fiber optics component that enables bi-directional transmission in optical fiber. It separates the transmitting signals from Port 1 to Port 2, and direct the receiving signals from Port 2 to Port 3. CIRM is designed to operate for all DWDM wavelength from 1528nm to 1565nm. This component provides high isolation, very low insertion loss, low polarization dependent loss (PDL), low polarization mode dispersion (PMD), and excellent environmental stability. CIRM is available in either a rugged module with SC/APC connectors or unpackaged device form. The module housing is fabricated with machined aluminum.
