Optical fiber sensors cover a wide area of applications. They have unique advantages such asimmunity to electromagnetic interference and biocompatibility. However, there are applications where they currently cannot be used because the required fiber-coupled read-out equipment is too expensive, too bulky or not mobile. Radio-over-Fiber technology being already widely used in communications can help to overcome this drawback and pave the way to numerous novel usage scenarios. Using multiplexing techniques (frequency or code division), many signals can be acquired at the same receiver. One important application scenario for the wireless read-out of optical sensors is within buildings and structures. In this paper, sensors for strain, temperature and moisture are presented, their packaging is discussed and the compatibility to the wireless read-out scheme isdemonstrated.
