3 Ports 1625nm Polarization Insensitive Optical Circulator

3 Ports 1625nm Polarization Insensitive Optical Circulator

The 3 Ports 1625nm Polarization Insensitive Optical Circulator is a high-performance non-reciprocal passive device designed to direct optical signals sequentially from Port 1 → Port 2 and Port 2 → Port 3 with minimal insertion loss and excellent isolation. Operating specifically at 1625nm, it is optimized for optical monitoring, fiber testing, and OTDR applications, where high wavelength selectivity and low polarization sensitivity are essential.

Featuring a polarization-insensitive design, this circulator maintains stable optical characteristics regardless of input polarization state, ensuring accurate and consistent performance across varying environments. Its compact and durable structure makes it ideal for integration into fiber optic communication systems, CWDM/DWDM networks, and optical power monitoring modules.

Application Diagrams

Circulator can be used to send optical signals through a single fiber in two directions.
As the picture shows: 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.
