Designing Fiber Optic Systems

Lasers and LEDS Electrical to optical video converters generally have a BNC coaxial cable connector at the input and a fiber optic connector on the output. In order to get the digital bits down the fiber optic cable, a light emitting device is used, onto which the digital signal is modulated. Either a laser or an LED (Light Emitting Diode) is used for this purpose. Lasers are more expensive, bu...

A fiber optic sensor for measuring glucose in aqueous solutions

In this paper, the set-up of a multi-mode fiber optic sensor for measuring glucose in aqueous solutions is investigated and evaluated. The basis of this sensor is based on the Fresnel Reflection. In this setup, a helium-neon laser is used as a light source, a fiber optic probe, photocell as detector and a digital multimeter. The statistical analysis of the recorded data shows a highly linear be...

MSE Equalization of Digital Fiber Optic Systems

Ahtract-The optimum minimum MSE equalization, both linear and decision feedback, of a digital fiber optic transmission system with Poisson signal statistics and additive wide-sense stationary noise is considered. The problem is reduced to the solution of a certain integral equation, with solutions obtained for certain special cases, including white and band-limited additive noise. Numerical res...
