Development of self-centering fiber connector components for Fiber-To-The-Home applications

Scriptie/masterproef: Master's Thesis


Since the spread of optical technologies, Fiber-to-The-Home (FTTH) networks have become adopted as a potential replacement of traditional electrical connections for "last mile" transmission of information with high bandwidth. Therefore, the development of a new breed of cost-effective connectivity solutions is necessary. This includes the introduction of key network components such as connectors, fiber distribution hubs, splitters and low-cost monitoring systems. One of the most important parameters that restrict the further integration of fiber optics in these networks is the fiber positioning accuracy. Indeed, contrary to electronic copper cables, optical single-mode fibers (SMFs) are very sensitive to spatial misalignments and deviations in the micrometer range result in unacceptably high coupling losses. The main objective of this work is to develop a field installable connector based on self-centering micro-mechanical structures that can alighn optical fibers and can accommodate for possible fiber diameter variations. This will be achieved by deflectable/compressible cantilever structures, providing a self centering functionality for the fiber. Simulations of the mechanical properties of the cantilever are carried out in order to get an analytical approximation and a mathematical model of the spring constant and the stress in the structure; we also included an introduction to the Deep Proton Writing technology for a rapid prototyping of thes micro-opto-mechanical components.
