Fiber Optic Cable Locator | DAS & OTDR Vibration Sensing Cable Fault Locator

Overview

This professional Fiber Optic Cable Locator is an advanced optical fiber detection device integrated withDAS (Distributed Acoustic Sensing) and high-precision OTDR composite technology, adopting professional dual-mode collaborative positioning principle for optical fiber fault location and cable tracing. The device works with a two-step precise positioning logic: it first uses high-precision OTDR technology to accurately locate the optical attenuation abnormal position along the fiber line. Then, technicians tap optical cables and manhole covers on-site to generate vibration signals, and the built-in DAS system captures and identifies real-time vibration feedback transmitted by the fiber. Combined with the OTDR optical attenuation data, it realizes accurate confirmation and precise positioning of fiber fault points, and quickly screens out target cables from densely bundled optical fibers. It is a professional-grade tool specially designed for precise fault positioning and cable sorting in complex optical fiber network operation and maintenance scenarios.

Key Features

• DAS + OTDR Dual Collaborative Positioning Technology: Adopts a professional two-step positioning mechanism combining DAS distributed acoustic sensing and high-precision OTDR technology. The OTDR module first locks the optical attenuation abnormal position of the fiber line; the DAS module captures on-site vibration signals generated by manual tapping on cables or pipeline facilities. The system cross-analyzes OTDR attenuation data and DAS vibration feedback signals to complete high-precision fiber fault location and target cable identification.
• Precise Fiber Fault Positioning & Cable Tracing: Effectively solves the pain point of difficult target cable identification for bundled and disordered optical fibers in pipe trenches, computer rooms and outdoor pipelines. It accurately locates fiber fault positions by combining optical attenuation detection and on-site vibration sensing verification, helping maintenance staff quickly confirm fault points and complete efficient cable sorting and line verification.
• Strong Anti-Interference & Professional Compatibility: Features excellent environmental anti-interference capability, maintaining stable and accurate positioning performance in complex scenarios including long-distance buried pipelines, overhead fiber lines and multi-cable clustered laying. It is professionally customized and fully compatible with single-mode optical fiber cables for mainstream telecom and communication networks.
• Visual Data Positioning & High Accuracy: Real-time signal analysis and data feedback, no blind detection. It can accurately mark the specific position of vibration response and abnormal points along the line, providing reliable data support for cable sorting, fault troubleshooting and pipeline maintenance.
• Portable Industrial-Grade Design: Compact and lightweight body, easy to carry for outdoor field operations. Industrial-grade drop-proof and wear-resistant shell, stable operation in low temperature, high temperature and complex construction environments, with long service life and low failure rate.
• Smart APP Matching & On-Site Visual Inspection: Equipped with dedicated supporting APP, compatible with mobile intelligent terminals. Field maintenance personnel can real-time view vibration signal data, signal strength and line feedback status on the mobile APP. The intelligent system assists in quickly distinguishing target cables from numerous bundled fibers, effectively avoiding cable misjudgment and improving the accuracy and efficiency of on-site cable searching and fault checking.

Product Advantages

Different from traditional single-function fiber testing tools, our fiber optic cable locator adopts innovative DAS distributed acoustic sensing + high-precision OTDR dual collaborative positioning technology, supporting up to 80KM OTDR long-distance optical attenuation detection and 40KM DAS vibration sensing positioning. It adopts a unique two-step working mode: first, OTDR accurately locks the optical attenuation abnormal position of the fiber line; then on-site tapping generates vibration signals, and the DAS system cooperates with OTDR data to verify and pinpoint the exact fiber fault location, while realizing fast identification of bundled target optical cables. Equipped with a dedicated mobile APP, it supports real-time signal data viewing and intelligent cable judgment, avoiding manual misjudgment. With long detection distance, high positioning accuracy and strong anti-interference ability, it greatly improves the efficiency of optical fiber line sorting, fault troubleshooting and daily operation and maintenance, and is a core professional device for telecom optical fiber engineering and maintenance teams.
