3-Port Optical Circulator
The 3‑port optical circulator is a compact, high‑performance component designed for efficient optical signal routing in fiber optic networks. It directs light sequentially from Port 1 to Port 2 and from Port 2 to Port 3, enabling bidirectional communication while maintaining excellent signal integrity.
With low insertion loss, high isolation, and low polarization‑dependent loss (PDL), this circulator ensures stable and reliable operation in demanding applications. Its epoxy‑free optical path enhances long‑term reliability, making it suitable for both telecom and sensing environments.
