OTDR FBG Reflector 1550nm SC APC with 1644.5-1655.5nm Bandwidth for PON Network Monitoring
The OTDR FBG Reflector is a wavelength-selective filter utilizing Fiber Bragg Grating technology, designed for precise monitoring of Passive Optical Network (PON) infrastructure. Operating at 1550nm with reflection bandwidth of 1644.5-1655.5nm, this component enables accurate end-to-end attenuation detection without disrupting normal communication traffic.
- High precision reflectance at test wavelength (1644.5-1655.5nm)
- Low insertion loss at traffic wavelength (≤1.0dB for 1260-1600nm)
- Exceptional reliability and environmental stability
- Easy installation with standard connector interfaces
- Maximum optical power handling: 27dBm
- FTTH, FTTB, FTTC network monitoring
- Compatible with GPON, EPON, GEPON, 10GEPON, NGPON systems
- Point-to-point and point-to-multipoint network testing
- Optical continuity verification and troubleshooting
- Central office reflectivity testing
FBG reflectors reflect nearly 100% of OTDR test pulses while allowing communication signals to pass through with minimal attenuation. This enables real-time fiber line detection without affecting normal data transmission.
The FBG area is completely encapsulated inside ceramic ferrules, providing protection against environmental factors and ensuring long-term stability across operating temperatures from -25°C to 65°C.
Available in SC/APC and LC connector types for seamless integration with conventional network adapters.
