Fiber Optic Sensor Networks and Monitoring Techniques
Joint Meeting with Boston Chapter, IEEE Photonics Society
Optical fiber development in communications and sensing started around 40 years ago but afterwards, they have had an unequal development. Fiber-optic sensor global market is growing and in the last years new technologies are available in specific niches where their electronic counterparts do not work properly. Development of new self-referencing techniques can also foster simple fiber-optic intensity sensors to be developed. Those techniques can also be applied to new integrated optics solutions based on intensity measurements. One of the main specific characteristic of fiber-optic sensors is its potential to be multiplexed so many points can be measured in different locations by using a single lead of fiber. Fiber-optic self-reference intensity networks can be developed using architectures proposed for broadband access networks. They can also share the use of specific devices already developed for communications applications. But the reverse can also be possible and successful strategies in the sensing domain can also be used to assist telecommunications needs. A review of different fiber-optic sensors will be given, showing techniques for reliable remote measurements in multiple points using fiber optic intensity sensor. An example of a cross-application from sensors to monitoring broadband access networks will also be described.
