Title:
OPTICAL TRANSMISSION SYSTEM DESIGN METHOD AND DESIGN DEVICE
Document Type and Number:
WIPO Patent Application WO/2024/084561
Kind Code:
A1
Abstract:
To solve the problems, the purpose of the present invention is to provide a design method for calculating optical transmission system parameters satisfying conditions required for an optical transmission system using a light source such as an LED and a bundled optical fiber as an optical transmission path. A design method according to the present invention designs an optical transmission system 301 comprising a light source 11 that outputs light L1, a bundled optical fiber 36 obtained by bundling a plurality of optical fibers and transmitting the light L1, a plurality of radiation units 13 each radiating light L2 to each radiation target area, and a plurality of single-core optical fibers 51a separated from the bundled optical fiber 36 and propagating light to each radiation unit 13, the design method being characterized by adjusting the parameters of the optical transmission system 301 such that the power of the light L2 output by each radiation unit 13 and calculated by using the parameters is a value considering energy required for each radiation target area.
