Product Description

Technical specifications for optical cable Routing Survey Instrument (JLU-NCV300Type 1)

• Introduction

Optical cable Route Censer (Non-Contact Vibration: JLU-NCV3001) uses DVS (Distributed Fiber-optic Vibration Sensor) technology, with non-contact vibration sensing vibration function, in the condition of no excavation, no drilling, no climbing pole, tapping vibration optical cable pipeline, manhole cover and bearing pole, you can probe optical cable routing. Measure the distance length of optical path; A certain optical cable in the optical cable cluster can be accurately identified by tapping the vibration optical cable body with contact sub-strength. The instrument is also equipped with Optical time domain reflectometry (OTDR) module, which can be used for regular inspection and maintenance of optical cables. The instrument can assist optical network maintenance personnel to realize efficient optical cable inspection, breakpoint location and optical attenuation point location, which can greatly improve the operation and maintenance efficiency of emergency repair.

• Key technology and performance

1. Using the industry's leading phase-based direct detection Optical time domain reflectometry (ΦOTDR: φOptical Time Domain Reflectometry) technology, with extremely sensitive optical fiber sensing technology, in non-contact optical cable conditions, well vibration isolation sensing slight vibration, efficient detection of optical cable location and path.
2. Using the transmission cable itself as the sensor, the detection distance can be up to 60km; OTDR can measure up to 80km.
3. The excitation light source uses a narrow line-width laser light source, and the analytical data card uses a dedicated FPGA high-speed data acquisition card based on ARM architecture. The range accuracy of the vibration instrument is better than 2 meters, the range accuracy of the OTDR instrument is better than 0.01dB, and the data update is less than 1S.
4. The instrument adopts cloud architecture, remote login operation, real-time remote access by APP, and the operation interface is simple.
5. The instrument adopts 8-port design to realize the simultaneous survey of 8 optical cables, which is more efficient.
6. The instrument built-in lithium battery, battery life of more than 8 hours, to meet the needs of outdoor operations.
7. Integrated small design, can be locked in the optical delivery box, no manual duty, saving labor costs.
8. The communication module with the full frequency band is compatible with 4G and wired connection, and the application scenario is wider.
9. SDK interfaces can be opened to asset management platforms and third-party platforms, and test data can be transmitted to the cloud platform in real time for storage and analysis; Large-scale application can complete the macro big data statistics, perspective and analysis of optical cable resources, providing a strong guarantee for network construction and operation and maintenance strategies.
