520 |a"This report describes the current status of modelling activities aimed at establishing test methods for fiber optic links and components. The fiber has been characterized by three different approaches. Its impulse response has been measured experimentally as well as computed from its index profile and from differential mode characteristics. The three impulse responses are compared. Launching conditions have been simulated to represent both the mode volume and the power profile (near-field pattern) of a source. A relationship between the modal power distribution and the near-field pattern is being sought. The complexities of this research are discussed. The fibre joint has been modelled partially. Matching conditions have been established between incoming and outgoing modes. Future activities are discussed"--Summary, page i.
