Product Description
Product Overview
HJY's 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 hybrid design combines laboratory precision with industrial durability for telecommunications, fiber sensing, and DWDM systems.
Key Features & Applications
Features
- High channel isolation up to 50dB
- Low insertion loss of 0.6dB typical
- High return loss exceeding 50dB
- Exceptional stability and reliability
- High power handling up to 30dBm (500mW)
Applications
- Optical fiber amplifiers
- CATV optical fiber links
- Optical fiber system testing
- Dispersion compensation systems
Application Diagram
Circulators enable bidirectional optical signal transmission through single fibers. Each circulator adds signals in one direction while removing signals in the opposite direction, creating efficient two-way communication systems.
