摘要：Thousands of kilometres of Optical Ground Wire (OPGW) have been installed by electrical utility companies for two main purposes which are telecommunication and grounding. As the demand of optical fibres keep increasing to fulfil the needs for long distance communication that is immune to weather, telecommunication companies prefer to lease the extra fibres from electrical utility companies. Unfortunately, bend of optical fibre contribute to the loss and attenuate the optical power. High optical power attenuation found after several months of cable installation and caused the system to be interrupted. In this paper, the attenuation of optical fibres of long OPGW is monitored and discussed. The monitoring activities have been done on installed OPGW cable belongs to an electrical utility company, Tenaga Nasional Berhad (TNB) of Malaysia to determine the attenuation of optical power in 10 months.
