Fiber Bragg Grating Reflector, also known as fiber grating terminal filter. When the optical measurement system send a certain frequency light waves from the front end of fiber tothe end of fiber, the FBG reflects the wavelength (1650nm ±5nm) waves, if the optical measurement system detects this wavelength, it is proved that the optical line is normal,no fiber damage and breakage, and other communication wavelength which are not inherent FBG reflection wavelength, will pass normally, does not affect normal communications.

Fiber Bragg Grating Reflector can be easily placed in series in the user end. The optical measuring system is connected to the front end of optical splitter, when detecting the presence of the center wavelength. It means optical fiber connection is normal, if the center wavelength does not exist or reflection values decrease, indicating that the fiber damage or breakage, require maintenance.

Features:

• Good repeatability

• Low insertion loss

• High resistance to electromagnetic interference

• Long lifetime

• High reliability

• Excellent optical characteristics

• Easy to use

Applications:

• FTTN,FTTC, FTTB,FTTH

• Optical network communication

• Long-distance line detection

FTTH (fiber-to-the-home): Fiber reaches the boundary of the living space, such as a box on the outside wall of a home. Passive optical networks and point-to-point ethernet are architectures that deliver triple-play services over FTTH networks directly from an operator's central office.

Currently in FTTH project, SC-type and TF attenuator reflector are widely used, SC-type structure require on-site connections on one side, TF attenuator type can be plugged directly on both sides.
