Abstract

Several of our proposed real-time non-intrusive fault surveillance schemes for various optical components and systems are reviewed here. These schemes make use of a combination of fiber Bragg gratings as sensors and Erbium doped fiber amplifiers in the system as the light sources. By means of a hierarchical layering of fault surveillance management, these schemes can be extended to cover the entire wavelength routing network. The surveillance information can be transmitted from one managing node to another by embedding in the network signaling protocol.
