3 Port Polarization Insensitive Optical Circulator for 1310nm or 1550nm Bands for Fiber Communication and EDFA Systems

HJY's Optical Circulator is a non-reciprocal passive device that directs light signals sequentially between ports (e.g., Port 1→2, Port 2→3, Port 3→1). It utilizes Faraday rotation and birefringent crystals to enable bidirectional optical routing with minimal loss. Key features include low insertion loss, high isolation, and compact design, making it ideal for telecommunications, fiber sensing, and dense wavelength-division multiplexing (DWDM) systems.

Features	Application
•High Channel Isolation •Low Insertion Loss •High Return Loss •High Stability and Reliability	•Optical Fiber Amplifier •CATV Optical Fiber Link •Optical Fiber System testing •Dispersion Compensation

Application Diagram:

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. see the example to the left.

Category	Types	Key Features
Port Configuration	3-Port	Standard unidirectional flow (Port 1→2→3→1)
	4-Port	Extended routing for complex network topologies
Application Grade	Telecommunication-Grade	High reliability for long-haul networks
	Industrial-Grade	Ruggedized for harsh environments (e.g., sensing)
