OTDR FBG 1650nm Fiber Optic SC Reflector
- Male and female structure
- Standard size, convenient and fast connection
- High-precision ceramic ferrules and sleeves
- Long-term stable mechanical and optical performance
Fiber grating filter is an important device for link detection in the communication. The principle is equivalent to a band-pass filter, which completely reflects the light from 1645nm to 1655nm, and all other wavelengths of light pass through. The communication light (C+L band) and the detection light can be separated, preventing the detection light from passing through and thus affecting the signal, and at the same time, the return light can be detected at the control end.
Features and Benefits:
- The grating is embedded and not affected by environmental pollution
- Low insertion loss and high reflectivity
- High reliability and long life
- Accurate control of the wavelength of the reflection band
- Easy installation
