Definitions
- the sensitivity of optical rings to mechanical stresses is maximum at the beginning of the optical ring, in any direction and is insensitive at the farthest end of the optical ring or in the middle of the ring, and the sensitivity of the optical ring gradually decreases from the beginning of the ring to the middle of the sensitive part, depending on the characteristics of the equipment used and is regulated by the total ring length of the sensitive part of the device.
- FIG. Figure 1 shows an example of the passage of a pulse for a certain period.
- FIG. Figure 2 shows the position of the sensitive part of the sensor — the fiber bending radius is less than the critical value at which the probe pulse reaching the fiber bending point penetrates the fiber sheath and is absorbed in it, as a result of which a reflection signal is not formed.
- a piece of standard single-mode fiber integrated in the optical circuit of the return device serves as a sensitive element.

Abstract
La solution technique concerne des équipements optiques et notamment des dispositifs de collecte d'informations sur les effets dynamiques sur des structures souples et l'état des avertisseurs d'extrémité à fibres optiques. Le dispositif de l'invention comprend une partie stationnaire, un câble de transport optique connecté par un contact optique à un réflectomètre, par une extrémité, et connecté par son autre extrémité à un splitter utiliser pour ramifier et continuer le transport d'énergie des impulsions de balayage vers les parties sensibles du circuit optique du dispositif, des bobines optiques de régulation, des diviseurs de la partie de transport du circuit optique ; des splitters destinés à former directement un anneau optique de la partie sensible du dispositif et des avertisseurs d'extrémité à fibres optiques. Les parties de transport ramifiées du dispositif sur une partie des splitters et des segments du câble de transport effectuent la division de l'énergie de l'impulsion de balayage jusqu'à un niveau de puissance suffisant pour assurer une valeur des signaux de réflexions par rapport à la partie sensible du circuit optique du dispositif dans une gamme nominale vis-à-vis de l'échelle de mesures du dispositif de réception et effectuent également l'acheminement de l'énergie d'une impulsion laser au lieu de connexion des splitters qui forment des anneaux optiques de la partie sensible du circuit optique du dispositif et des signaux de formation de retour de l'impulsion de balayage vers le dispositif de réception. Le résultat technique consiste à assurer la possibilité d'utiliser en tant que support d'informations principal un signal de réflexion ou de retour utilisant une petite partie de puissance de l'impulsion de balayage, en fonction du dispositif émetteur/récepteur utilisé.
