Altice Labs is thrilled to announce the granting of a new European patent entitled “Method for Configuring an FTTH Distribution Network Cell.” This innovation introduces advanced methods for configuring FTTH (Fiber to the Home) network cells, optimizing the use of GPON (Gigabit Passive Optical Network) ports in low-density residential areas and SMBs (Small and Medium-Sized Businesses).
In typical FTTH topologies, GPON ports and splitters are often underutilized due to low network penetration rates. Additionally, failures in a GPON port or splitter can impact all connected customers. The patented solution from Altice Labs involves cross-connections between splitters and Optical Distribution Points (ODPs), ensuring an even distribution of splitter coverage throughout the network cell. This method supports the progressive activation of GPON ports in Central Offices as customer numbers grow, reduces simultaneous failures by distributing the splitters’ load among multiple PDOs, and optimizes the use of GPON ports based on the target penetration rate set by the operator.
The invention also employs a round-robin algorithm to connect fibers from splitters to multiple PDOs, guaranteeing uniform and efficient coverage. With a “pay-as-you-grow” strategy, operators can reduce initial costs by tailoring infrastructure expansion to market needs. Key benefits of this technology include better utilization of network resources, reduced initial costs, enhanced resilience to failures, minimized service interruptions, and dynamic infrastructure planning that adapts to market demand.
The inventors of this patent are João Guerrinha, Pedro Carvalhido, Manuel Romeiro from the Business and Operations Support Systems department, and Ricardo Cadime from the Innovation Strategy and Communication department at Altice Labs.
This invention also has patent applications underway in the United States and Brazil, underscoring its global potential.
