Design, deployment and maintenance of optical cables associated to overhead transmission lines
This TB is a thorough overview on OPGW encompassing its project management, its designs, its testing, its installations and its maintenance since its creation in the early 1980s. As a whole, the industry has coincided into common project approaches, into a general rally around metallic tube with a high count of fibres of new generations of improved telecommunications transmission performance, into standard construction practices and into mitigative actions in maintenance.
The full scope is validated from the analysis of the survey included in the TB.
Nevertheless, the subject is not exhausted and has seen continuous lessons learned and new ventures in topics such as OPPC, DTS and DSTS. One further topic of recent interest because of product 30-year history of deployment is the assessment of its reliability and if the actual performance meets the design predictions. This latest topic remains the complex subject of future studies because of the variety of the conceptual configurations that were deployed.
