Product Description
Product Description
Our Featured Isolators and Circulators are high-performance optical components designed for unidirectional signal transmission. Isolators ensure light travels in one direction, while circulators route signals to specific ports in sequence. Both devices utilize Faraday rotators and polarization optics to achieve high isolation and low insertion loss. Available in various configurations (2-port, 3-port), they are ideal for laser systems, amplifiers, and fiber optic networks.
Features
High Isolation: Isolators offer ≥30 dB isolation; circulators ≥25 dB.
Low Loss: Insertion loss ≤0.5 dB for both devices.
Wide Wavelength Range: Supports 1260–1625 nm for telecom and datacom applications.
High Power Handling: Supports up to 1 W of optical power.
Compact Design: ≤25mm length for easy integration.
Applications
Laser Systems: Protects lasers from back reflections.
EDFAs: Prevents signal degradation in optical amplifiers.
Fiber Sensors: Enables bidirectional sensing in distributed systems.
Optical Networks: Routes signals in DWDM and ROADM systems.
Aerospace: Reliable performance in airborne laser systems.
Faq
