1. Product Summaries

Techwin Brillouin Optical Time Domain Reflectometry (BOTDR) TW3600 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). 
TW3600 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. 
TW3600 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.
