Web based e-learning software for optical link design

Abstract

In distance learning, web-based software may provide an alternative to installation of expensive software on the student computer, or an alternative to expensive laboratory equipment. This paper describes the original web-based e-learning software, which enables teaching and learning of the optical link design. Optical link design is an iterative process involving trade-offs to achieve the desired performance: bit error rate, transmission distance, etc., at minimal cost. Fundamental elements of an optical fiber transmission link are the optical transmitter, the optical fiber with associated splices and connectors, and the optical receiver. The student must select appropriate devices from a set of available optical components to meet a given set of system requirements. Data concerning optical equipment that can be used for specific optical link design are stored in a database, that was created for the purpose of this software.
