This research presents the key elements for designing a fiber optic sensing interface used in medical device applications where low power requirements are needed. The goal is to identify the major areas in which signal throughput is most affected. In order to classify the best design fit for use in medical devices, many considerations are taken due to the rigorous regulatory requirements. Signal throughput is the ultimate goal but there are many other factors such as biocompatibility, safety, tolerancing and many others. Fiber optic samples were tested thoroughly in the following ways: optical fiber types, chemical resistance, fiber bend radius, length vs signal, and material. All tests were done in the visible light spectrum from 430nm-700nm wavelengths. The fiber samples were also tested using various connector methods. A comparison analysis was conducted for fiber to fiber and lens to fiber configurations. This is of significant importance because fiber optic cable loss is highest at its connection interfaces. The overall intent is to find the optimal connector configuration for low emission signals collected through optical fibers.
