Novel monitoring technique for passive optical networks based on optical frequency domain reflectometry and fiber bragg gratings
(Optical Society of America, 2010-07)
An efficient monitoring method having a very short measurement time (a few seconds) is proposed. The equal-length branches can be effectively monitored, but also the information of temperature at any place in the network ...
Optical layer monitoring in passive optical networks (PONs): A review
Motivations, challenges and requirements of optical layer monitoring in PONs are discussed. An exhaustive review of monitoring systems is given considering both Time-Division Multiplexed PON (TDM-PON) and Wavelength-Division ...
Complete analysis of multireflection and spectral-shadowing crosstalks in a quasi-distributed fiber sensor interrogated by OFDR
We present the analysis of a quasi-distributed fiber sensor based on the concatenation of identical low-reflective fiber Bragg gratings (FBGs) taking into account both multireflection and spectral-shadowing crosstalks. ...
Optical Frequency Domain Reflectometry: A review
In this paper, we discuss the operation principles, challenges and application areas of optical frequency domain reflectometry technique. A review of OFDR systems is given considering both Incoherent-OFDR and Coherent- ...
