| Abstract: |
| ObjectiveTo study long-term reliability of plastic pipes for telecommunication to protect optical fiber cables.MethodsBy means of naturally burying various plastic pipes for telecommunication in soil at different testing sites such as Lhasa，Geermu，Kuerle and Yingtan where the soil environments were harsh and periodically testing soil factors and soil microbes，the changes of their appearances and mechanical performances and the relation to the environment were studied.ResultsExcept for individual color changes，the pipes kept their main mechanical performances well after the specimens were buried underground for8years. The physicochemical properties of soil and soil microbes had little effect on them. ConclusionPlastic pipes for telecommunication could protect optical fiber cables for a long time in soil. Hiding the cables in plastic pipes is a reliable way to construct underground telecommunication route. |
