SC 1650nm 1625nm Fiber Bragg Grating Filter FTTH Optical Grating Reflector

Description

Product description and application

Fiber Bragg Grating (FBG) filter at 1650 nm is an important device for communication link detection in optical communication field. The principle is equivalent to a band-pass filter, which completely reflects the light from 1643.5 to 1656.5 nm (the return ratio is more than 99.5%) and passes through all other wavelengths. In the field of communication, the communication light (C+L band) can be separated from the detection light to prevent the detection light from passing through, thus affecting the communication signal. At the same time, the return light can be detected at the control end. Its advantages are precise control, stable operation and long service.

Features

• The grating is embedded in the optical fiber and is not affected by environmental pollution;
• High reliability and long life;
• High reflectivity for the band to be blocked (above 99.5%), close to total reflection;
• Precise wavelength control of the reflection band (1643.5nm~1656.5nm);
• The transition area is very narrow (less than 2nm) at the edge of the bandpass, and it is all passed through this area;
• Using standard and general adapter structure, easy to connect;
