FBG Reflector
Description
FBG reflector production is based on FBG with wide bandwidth and low insertion loss. The working principle is that when the optical measurement system generates a certain range of wavelength to the optical network which can through the FBG, the FBG reflectors its own intrinsic reflection wavelength (1645-1655nm). If the measurement system can detect the reflection wavelength, it is proved that the optical fiber connection is normal.
Characteristics
- High stability and reliability
- Remote real-time detection
- Low insertion loss
