Product Description
Product Overview
HJY's Broad Spectrum 3-Port Optical Circulator is a non-reciprocal passive device that directs light signals sequentially between ports (Port 1→2, Port 2→3, Port 3→1). Utilizing Faraday rotation and birefringent crystals, it enables bidirectional optical routing with minimal loss. This circulator features low insertion loss, high isolation, and compact design, making it ideal for telecommunications, fiber sensing, and dense wavelength-division multiplexing (DWDM) systems.
Key Features & Applications
Technical Features
- High Channel Isolation up to 50 dB
- Low Insertion Loss as low as 0.6 dB
- High Return Loss exceeding 50 dB
- High Stability and Reliability for data center operations
Primary Applications
- Optical Fiber Amplifier systems
- CATV Optical Fiber Link networks
- Optical Fiber System testing equipment
- Dispersion Compensation modules
Application Diagram
Circulators enable bidirectional optical signal transmission through a single fiber. As shown in the diagrams, circulators positioned at both fiber ends add signals in one direction while removing signals in the opposite direction, facilitating efficient two-way communication.
