Description

Technical Field

[0001] The utility model relates to the technical field of optical cable detection, in particular to an optical cable composite drip test fixture. Background Art

[0002] At present, most of the communication optical cables used in the market are of the filled type, that is, the loose tube and the gap of the cable core are filled with thixotropic paste to directly protect the optical fiber from external impact and prevent moisture from invading the optical fiber. This type of optical cable has a test called drip flow, which aims to verify whether the used paste will drip out of the optical cable at a specified high temperature, so as to judge the viscosity of the paste at high temperature. The paste is generally a composite composed of various substances such as carbohydrates, organic compounds, and chemical plasticizers. The drip flow test of the optical cable requires the optical cable to be suspended in a constant temperature box. The existing technology lacks a fixture for hanging the sample, which makes the test inconvenient. Utility Model Content
