Title
(EN) OPTICAL FIBER COMMUNICATIONS SYSTEM AND CORE WIRE CHECKING SYSTEM
(FR) SYSTÈME DE COMMUNICATIONS PAR FIBRES OPTIQUES ET SYSTÈME DE VÉRIFICATION DE CÂBLE CENTRAL
(JA) 光ファイバ通信システム及び心線対照システム
Abstract
(EN) The purpose of the present disclosure is to enable identification of optical communications wiring without on-site measurement. The present disclosure is an optical fiber communications system comprising multiple core parts covered by cladding, wherein the multiple core parts include cavities and the core parts each have a different number of cavities and/or different cavity diameter.
(FR) L'objectif de la présente invention est de permettre l'identification d'un câblage de communications optiques sans mesure sur site. La présente invention concerne un système de communications par fibres optiques qui comprend de multiples parties centrales recouvertes par une gaine, les multiples parties centrales comprenant des cavités et les parties centrales ayant chacune un nombre différent de cavités et/ou un diamètre de cavité différent.
(JA) 本開示は、現地での測定を行うことなく光通信配線の識別を可能にすることを目的とする。 本開示は、クラッド部で覆われている複数のコア部を備える光ファイバ通信システムであって、前記複数のコア部は空洞を備え、各コア部に備わる前記空洞は、それぞれ、前記空洞の数又は直径の少なくともいずれかが異なる、光ファイバ通信システムである。
