Product Description
Product Overview
HJY's 3-Port Optical Circulator is a high-performance 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.
Key Features
- Low insertion loss (typical 0.6 dB, maximum 0.8 dB)
- High channel isolation (minimum 40 dB, maximum 50 dB)
- High return loss (>50 dB)
- Epoxy-free design for enhanced reliability
- Compact dimensions (Φ5.5×50mm or 90×20×9.5mm)
- Operating temperature range: 0°C to +70°C
Applications
- Optical fiber amplifiers
- CATV optical fiber links
- Optical fiber system testing (OTDR)
- Dispersion compensation
- Dense wavelength-division multiplexing (DWDM) systems

Application Diagram
Optical circulators enable bidirectional signal transmission through a single fiber. As shown in the diagrams, circulators at both fiber ends add signals in one direction while removing signals in the opposite direction.
