Ce localisateur visuel de d\u00e9fauts (VFL) est sp\u00e9cialement con\u00e7u pour les techniciens de terrain qui ont besoin d'un outil efficace et \u00e9conomique pour le tra\u00e7age et l'acheminement des fibres, ainsi que pour la v\u00e9rification de la continuit\u00e9 dans les r\u00e9seaux optiques. Le VFL permet de d\u00e9tecter les points de rupture, les points de connexion d\u00e9fectueux, les courbures ou les fissures dans les c\u00e2bles \u00e0 fibre optique ; il permet \u00e9galement de localiser les d\u00e9fauts situ\u00e9s dans la zone morte d'un OTDR et peut \u00eatre utilis\u00e9 pour l'identification visuelle des fibres de bout en bout.  <\/p>\n\n\n\n

Le VFL \u00e9met une lumi\u00e8re visible de 650 nm dans une fibre optique. Lorsque cette lumi\u00e8re rencontre une rupture ou un coude prononc\u00e9, elle se diffuse, et la lumi\u00e8re diffus\u00e9e peut \u00eatre observ\u00e9e \u00e0 la sortie du c\u00e2ble. Plus important encore, le VFL permet de localiser les points de rupture dans les cordons de raccordement courts, que l\u2019OTDR ne peut pas d\u00e9tecter en raison de sa \u00ab zone morte \u00bb de fonctionnement.<\/p>\n\n\n\n

The Visual Fault Locator can be operated in either continuous wave mode (CW mode) or in pulsed mode. Pulsed mode aids in locating faults under high ambient light conditions and improve battery life. It also could be used in  checking connector quality. <\/p>\n\n\n\n

NOTE: Customers need to buy battery by themself, because battery is refused by most mail agent to carry. This VFL uses normal AAA battery, so customers can easily get them from their local market. <\/p>\n\n\n\n

FAQ<\/h2>\n\n\n\n

Q1: What are the primary functions and applications of the FF-VFL-A Visual Fault Locator?<\/strong> <\/p>\n\n\n\n

R :<\/strong> The FF-VFL-A is designed for field workers needing an efficient tool for fiber tracing, fiber routing, and continuity checking in optical networks. It launches 650nm visible light to identify breakpoints, poor connections, bends, or cracks, including faults located within OTDR dead zones.<\/p>\n\n\n\n

Q2: What model options, output power levels, and detecting ranges are available in the FF-VFL-A series?<\/strong> <\/p>\n\n\n\n
