Product Description
Customized FBG Fiber Bragg Grating Reflector for OTDR Testing
The FBG fiber grating reflector is a wavelength-selective component designed for optical network monitoring. Installed at the front end of Optical Network Units (ONUs), it enables precise and rapid detection of end-to-end attenuation in optical links.
Product Variants
FBG Reflector (1550nm)
This FBG filter variant works with OTDR equipment to enable point-to-point (PTP) or point-to-multipoint (PTMP) network monitoring, accurately detecting network anomalies.
FBG Reflector (1650nm)
Utilizing the wavelength-selective properties of Fiber Bragg Grating technology, this reflector is embedded in adapters for easy installation and precise fault detection.
Pigtail Typed FBG Reflector

Key Advantages
Non-Interfering Communication
The FBG reflector reflects nearly 100% of test light pulses from OTDR equipment while allowing other communication signals to pass through with minimal attenuation, enabling online rapid detection without disrupting normal operations.
High Stability and Reliability
Fabricated using the photosensitivity of fiber material with grating areas encapsulated in ceramic ferrules, ensuring protection during insertion/removal cycles and resistance to environmental contaminants.
Easy Connectivity
Available in SC and LC connector types that interact seamlessly with standard adapters, providing convenient installation and maintenance.
