A multi-stress environmental chamber for the aging of all-dielectric self-support fiber optic cables

This paper presents an environmental chamber built at Arizona State University for the long-term aging test of ADSS fiber optic cables. Five 14-foot long cable samples can be tested in the chamber under a series of stresses, including UV radiation, salt fog, clean rain, and mechanical tension. The voltage and leakage current can be recorded continuously for the analysis of aging effect. With the environmental chamber, a better understanding and prediction of the aging and failure mechanism of ADSS fiber optic cables in service would be achieved.
