Fiber Bragg Grating OADM
Optical add-drop multiplexer, using a fiber Bragg grating and two circulators. A fiber Bragg grating (FBG) is a type of distributed Bragg reflector constructed in a short segment of optical fiber that reflects particular wavelengths of light and transmits all others. This is achieved by creating a periodic variation in the refractive index of the fiber core, which generates a. ansmission capacity to promote their networks periodically to high data rates or large number of wavelengths. It permits single or many wavelengths to be added and/or dropped from atrans-port fiber without.
