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.The SC/APC 1650nm Bidirectional FBG Reflector is a specialized optical component designed for precise wavelength reflection in fiber optic systems, particularly for bidirectional communication and sensing applications.
Key Features:
- Connector Type: SC/APC (Angled Physical Contact) connectors, which reduce back reflections and improve connection quality.
- Wavelength: Specifically designed for 1650nm, making it suitable for applications requiring reflection at this wavelength.
- Bidirectional Functionality: Capable of reflecting the 1650nm wavelength in both directions, making it ideal for bidirectional communication systems.
- FBG Technology: Utilizes Fiber Bragg Grating (FBG) to reflect the 1650nm wavelength while transmitting others.
Benefits:
- High Precision: Ensures accurate reflection at the specified 1650nm wavelength.
- Low Insertion Loss: Minimizes signal loss for non-reflected wavelengths.
- Robust Design: SC/APC connectors provide reliable and stable connections, essential for maintaining signal integrity in bidirectional systems.
