Aperfeiçoamento de rede ótica passiva em empresas provedoras de serviços de telecomunicações corporativos

Abstract

The increase in data consumption in the world means that companies providing telecommunications services need to increasingly expand the offer of optical fiber as a means of access, given that this technology is better suited to increase traffic. This expansion relies on passive network technology, in the various standards on the market, such as EPON and GPON. However, the growth of the optical network can become a problem when it does not go through a cautious expansion project. As a result, it is common to find optical networks with overcrowded cables, compromised power budget and difficulty in activating new customers, whose problems are strongly triggered by the poor distribution of optical splitters present in passive networks. This work aims to establish a methodology capable of mitigating the aforementioned problems through an improvement process based on the use of asymmetric splitters and planned physical changes in the existing network. A case study was carried out to prove the use of the method, increased by the possibility of aggregation between the GPON and XGSPON standards, and finalized by presenting the savings generated with this process when compared to the launch of a new optical cable.
