Abstract:
The present invention discloses a logging encapsulated optical-fiber duct cable and a manufacturing method thereof. The encapsulated optical-fiber duct cable mainly comprises an external encapsulation layer. At least one armor tube is arranged in the encapsulation layer. An optical fiber protective tube is arranged in each armor tube. A filling layer is arranged in a space between the optical fiber protective tube and the armor tube. An optical fiber is arranged in the optical fiber protective tube. The manufacturing method mainly comprises four steps: pavement of the optical fiber and formation of the protective tube, formation of the filling layer, formation of the armor tube and formation of the encapsulation layer. The optical-fiber duct cable of the present invention has the advantages of large length, high strength, good temperature tolerance, small signal transmission loss, high transmission speed and synchronous transmission of multiple signals.
