1577nm XGSPON WDM Reflector

Description:
1577nm fiber grating filter is an important device for communication link detection in the field of optical communication. The principle is equivalent to a band pass filter, which completely reflects back the light from 1572nm to 1582nm (the return ratio is more than 99.5%), and all other wavelengths of light pass through. When used in the field of communication, it can separate the communication light from the detection light, prevent the detection light from passing through and thus affect the communication signal. At the same time, it can detect the return light at the control end. Its advantages are accurate control, stable operation and long service life.

• Features:
  - The grating is embedded in the optical fiber and is not affected by environmental pollution
  - High reliability and long service life
  - High reflectivity (higher than 99.5%) for the band to be blocked, close to total reflection
  - Accurate wavelength control of reflection band (1572nm~1582nm)
  - The transition zone at the bandpass edge is very narrow (less than 2nm), and it is all-pass when passing
     through this zone
  - Based on FBG technology
  - Easy to install
  - Exceptional reliability and environmental stabiliity
  - RoHs compliant

• Applications:
  - FTTX network
  - FTTX troubleshooting

1650nm OTDR WDM Reflector

Description:
1650nm fiber grating filter is an important device for communication link detection in the field of optical communication. The principle is equivalent to a band pass filter, which completely reflects back the light from 1645nm to 1655nm (the return ratio is more than 99.5%), and all other wavelengths of light pass through. When used in the field of communication, it can separate the communication light from the detection light, prevent the detection light from passing through and thus affect the communication signal. At the same time, it can detect the return light at the control end. Its advantages are accurate control, stable operation and long service life.
