Product Description
Product Overview
HJY's 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 exceptional performance characteristics ideal for telecommunications, fiber sensing, and DWDM systems.
Key Features
- High channel isolation up to 50 dB
- Low insertion loss of 0.6 dB typical
- High return loss exceeding 50 dB
- Exceptional stability and reliability
- Compact design for space-constrained installations
Applications
- Optical fiber amplifiers
- CATV optical fiber links
- Optical fiber system testing
- Dispersion compensation systems
Application Diagram
Circulators enable bidirectional optical 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.
