“…In networks, wavelength routing is provided via OXC, which is used to connect any two topologies. There are two different types of OXC switches one is the digital switch which is opaque or hybrid the second one is transparent OXC [47]. With the use of electronic cross-connection technology, optical data streams are first changed into electronic data in the digital OXC switch, which is then transformed back into optical data streams.…”

In this article, the performance of a fixed grid network is examined for various modulation formats to estimate the system's capacity and spectral efficiency. The optical In-phase Quadrature Modulator (IQM) structure is used to build a fixed grid network modulation, and the homodyne detection approach is used for the receiver. Data multiplexing is accomplished using the Polarization Division Multiplexed (PDM) technology. 100 Gbps, 150 Gbps, and 200 Gbps data rates are transmitted under these circumstances utilizing various modulation formats. Various pre-processing and signal recovery steps are explained by using modern digital signal processing systems. The achieved spectrum efficiencies for PM-QPSK, PM-8 QAM, and PM-16 QAM, respectively, were 2, 3, and 4 (bits/s)/Hz. Different modulation like PM-QPSK, PM-8-QAM, and PM-16-QAM each has system capacities of 8-9, 12-13.5, and 16-18 Tbps and it reaches transmission distances of 3000, 1300, and 700 kilometers with acceptable Bit Error Rate (BER≤ 2× 10-3 ) respectively. Peak optical power for received signal detection and full width at half maximum is noted for the different modulations under a fixed grind network.

“…Cenários com essa variedade de interconexões aumentam a complexidade do problema. Com isso, novas arquiteturas de rede metro são pensadas para promover, com baixo custo, a melhoria e escalabilidade da maioria dos servic ¸os [de Sousa and Drummond 2023].…”

“…Geralmente as topologias da metro possuem maior quantidade de nós do que as redes de núcleo, e consequentemente enlaces. A escalabilidade dessas arquiteturas de rede tem demandado maiores investimentos para apoiar a escalabilidade da infraestrutura, em topologias que tem evoluído do formato em anel para o formato em malha [de Sousa and Drummond 2023].…”

“…Os operadores de telecomunicac ¸ão em Redes Ópticas Metropolitanas (ROM ou metro) têm sido cada vez mais desafiados a melhorar o desempenho da sua infraestrutura enquanto atendem as crescentes demandas de capacidade e velocidade das tecnologias disruptivas, como por exemplo, a Internet das Coisas (IdC) [de Sousa and Drummond 2023]. Os clientes desses operadores, principalmente grandes empresas e instituic ¸ões, necessitam de largura de banda escalável e flexível para a manutenc ¸ão dos seus negócios.…”

A EON é capaz de prover maior quantidade de recursos otimizados para os diversos perfis de aplicac ¸ões, mas até o momento a maior parte das soluc ¸ões estudadas não consideram as informac ¸ões sobre essas áreas/clusteres na tomada de decisão.…”

As redes ópticas metropolitanas (ROM)s concentram grande parte do tráfego que vem da internet, assim como agrega todo o tráfego proveniente das redes de acesso. A distribuição desse tráfego na ROM ocorre de diferentes maneiras e em diferentes tipos de áreas, seja em decorrência do padrão de atividades da população ou do horário do dia. Assim, um desequilíbrio do tráfego é percebido ao longo das áreas enquanto muitos recursos permanecem ociosos, aumentando a taxa de bloqueio dos serviços. Este trabalho propõe a utilização de algoritmos de roteamento e alocação de espectro ciente da área e de clusteres de áreas. A solução proposta demonstra o dobro de melhoria dos resultados de bloqueio em comparação com algoritmos agnósticos das áreas.

In modern conditions of organizing the work of IT infrastructure, the issue of increasing the efficiency of the optical network is relevant and in demand. In this regard, to formalize methodological approaches and argue the theoretical prerequisites for increasing the efficiency of optical networks, an in-depth analysis of the main methods and directions was carried out. The advantages of using the method of transforming the architecture and topology of the network are argued. The main types of optical networks are stated: passive, hybrid, elastic, followed by highlighting key technologies and identifying promising options for increasing efficiency. Optimization opportunities highlighted operation of an optical network using PoF cable and super coherent technologies. Aspects of a software solution to improve the efficiency of an optical network are touched upon. The use of redundancy is justified as one of the promising methods to improve the efficiency of an optical network. Methodological approaches to increasing the efficiency of optical networks have been formed and can be applied in practice when organizing information architecture using the main results of the study.
