3 Port Circulator

  • gpc-circulator-1.jpg

Reference number: GPC-CIR

General Photonics’ fiber optic circulators are compact, high-performance light-wave components that separate signals traveling in opposite directions along fibers by transmitting signals from port 1 to port 2 and port 2 to port 3, while blocking signals traveling in the opposite directions.
