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 telecom-grade component 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: 0.6 dB typical
- High return loss exceeding 50 dB
- Exceptional stability and reliability
- Compact, space-efficient design
Primary Applications
- Optical fiber amplifiers
- CATV optical fiber links
- Optical fiber system testing
- Dispersion compensation systems
Application Diagram
Circulators enable bidirectional optical signal transmission through a single fiber. As shown in the diagrams below, circulators positioned at both fiber ends add signals in one direction while removing signals in the opposite direction.
