Features
Optical isolation function:
Allows one-way transmission of optical signals, prevents reflected light from returning to the light source, and protects the laser from interference by reflected light.
Wavelength Division Multiplexing Function:
Combines optical signals of multiple wavelengths into a single fibre for transmission (multiplexing).
Separates multiple wavelength signals in a single fibre into separate channels (demultiplexing).
Signal protection and optimisation:
Improves system stability and reduces noise and signal distortion caused by reflected light.
Highly Integrated:
Simplifies optical path design by integrating isolator and WDM functions in a compact device.
Applications
Optical communication systems:
Fibre optic networks: for long-haul transmission and metropolitan area networks (MANs) to improve signal quality and system reliability.
Data Centre Interconnect: for multi-wavelength transmission and reflected light isolation in high-speed optical modules.
Fibre Lasers:
Laser Protection: Prevents reflected light from damaging lasers and improves laser life and stability.
Multi-wavelength laser system: Supports multi-wavelength laser generation and transmission.
Optical Sensing Systems:
Distributed Fibre Optic Sensing: for multi-wavelength sensing signal transmission and reflected light isolation.
Environmental monitoring: for high stability optical signal transmission in complex environments.
Test & Measurement:
Optical test equipment: for signal isolation and multiplexing in multi-wavelength test systems.
Medical Devices:
Laser medical equipment: protection of laser sources and optimisation of signal transmission in laser therapy and diagnostic equipment.
