3 port optical circulator
The three-port optical circulator provided by OPTICO is a high-precision and high-stability passive optical component, designed for fiber optic systems that require polarization maintenance, low loss, and directional isolation. This circulator is engineered to enable unidirectional signal transmission, ensuring that light flows in a specific direction between the three ports, making it especially suitable for fiber optic sensing, laser systems, and high-performance communication systems. This device effectively isolates reflected light and reduces return loss, providing a high-performance solution for various fiber optic applications.
This product is catagoried as conventional type and polarization mataining (PM fiber) type.

Highlight Features
Port 1 → Port 2: The light signal travels from Port 1 to Port 2.
Port 2 → Port 3: The light signal then travels from Port 2 to Port 3.
Port 3 → Port 1 (typically unused): This path is generally avoided to prevent unnecessary back reflections.
- Low Insertion Loss: Typical insertion loss is below 1 dB
- High Isolation: Isolation is typically above 40 dB, effectively preventing reverse interference between ports and ensuring unidirectional signal flow.
- High Stability: 1550nm wavelength offers enhanced stability against temperature and environmental variations, making it suitable for long-distance fiber transmission applications.
Can be configured with multiple connector types (such as FC/APC, FC/PC, SC/APC, etc.) to meet the specific needs of users.
OPTICO provides a variety of models of 1550nm PM optical circulators, supporting customized services with different package sizes, wavelength bandwidths and power levels.
- Add-Drop Multiplexing
- Fiber Optic Sensors
- Bidirectional Pumping Bidirectional Signal Transmission Systems
- Coupling In-Line Dispersion Compensation Devices
Applications
Circulators can also be used to send optical signal in two directions down a single fiber. A circulator is located at both ends of the fiber. Each circulator functions to add a signal in one direction while removing the signal in the other. See the example as below.
