AV6419 Distributed Optical Fiber Strain Tester 3D Display Of Loss Distribution

Product Summaries

AV6419 distributed optical fiber strain tester can measure strain distribution, loss distribution and Brillouin scattering spectrum at different location of optical fiber simultaneously, and can display 3D traces and multiple distribution parameters. It has the advantages of high strain measurement accuracy, good measurement repeatability, non-destructive measurement via one end, and it has become the indispensable instrument in the field of optical fiber communication and optical fiber sensor (OFS).

AV6419 is used widely in the fields of health monitoring of bridge building, dam, tunnel, lofty building, oil well platform and oil pipeline, and also in the fields of forecasting of geological hazard, such as mountain landslide, mud-rock flow and earthquake, and the fields of the intelligent structure monitoring of seaborne naval vessels and aviation aerospace.

AV6419 is also used to measuring the strain distribution of optical fiber loop or subsea optical cable in process of development, production and maintaining of fiber-optic gyroscope (OFG) , optical fiber hydrophone and subsea optical cable

Main Features

nondestructive measurement through single-end
Distribution measurement of Brillouin scattering spectrum width
Distribution measurement of optical fiber strain
Distribution measurement of optical fiber loss
Measurement of Brillouin scattering spectrum
Display multiple distribution traces simultaneously

Multiple-Window Display

The optical fiber strain at different location, Brillouin scattering spectrum, spectrum width and Brillouin scattering power distribution can be seen by multiple-window display simultaneously.

Ability of long-distance detection

AV6419 can measure the loss distribution of optical fiber link up to 80km.

High distributed stratin measuring acuracy

Under condition of 10ns pulse width, The strain measured accuracy of AV6419 BOTDR is achieved about±18με at distance of 11km optical fiber

Typical Application

Submarine optical cable strain distribution monitoring

It is necessary to measure the strain distribution of the submarine optical fiber cable during the phases of production , checkout after the arrival, checkout and maintenance before and after the construction, in order to prevent the optical fiber from breaking due to the large strain, which can further break off communication and bring about large damage.

AV 6419 is compliant to measure the strain distribution during all the phases of production, transport and construction of optical fiber cables.
