With new routes, the internet provider from Paraná has been expanding its operations to cities in Santa Catarina, Mato Grosso do Sul, and the borders with Paraguay and Argentina.
Expanding and upgrading its fiber optic network to ensure speed and stability for its customers’ connections – from companies and public and private institutions to end users. This is the goal of Ampernet Telecom, an internet provider operating in around 40 Brazilian cities – most of them in the state of Paraná – which is investing in Padtec’s technology and equipment to enhance its internet and telephony services through a fully optical network.
“With investments in new technologies, we are prepared to meet the growing demand from customers for higher transmission capacity and, at the same time, to prepare our network for the future,” says Thiago Luquini, CEO of Ampernet Telecom. In addition to Paraná, where it began and maintains its headquarters (in the city of Ampére), the provider also operates in cities in the states of Santa Catarina and Mato Grosso do Sul, as well as in neighboring Argentina and Paraguay.
Luquini points out that, in 2025, Ampernet expanded its operations to the metropolitan region of Curitiba, western Paraná, and southern Mato Grosso do Sul. “With a new route recently built on the Ayrton Senna Bridge, which crosses the Paraná River, we reached Mato Grosso do Sul with our own fiber optic network, delivering high-speed connections and also creating a redundant route to Paraguay,” says the Ampernet director.
The Ayrton Senna Bridge, 3,607 meters long, connects the cities of Guaíra (PR) and Mundo Novo (MS), linking the agricultural frontiers of Brazil’s North and Midwest regions with the South, in addition to facilitating access to shopping tourism in Paraguay. Ampernet’s optical network covers this area and also reaches the borders with Paraguay via the Friendship Bridge and with Argentina via the Tancredo Neves Bridge.
At the end of last year, the provider invested in upgrading its DWDM (Dense Wavelength Division Multiplexing) network, which currently spans approximately 2,300 kilometers. The upgrade includes the adoption of Padtec’s ROADMs (Reconfigurable Optical Add/Drop Multiplexers) with FlexGrid technology on some segments of the network.
“A FlexGrid DWDM network offers greater flexibility in allocating bandwidth for channels over the fiber, enabling the optimal configuration of each one according to requirements and optimizing the use of the fiber’s spectrum,” explains Henrique Graciosa, Padtec’s Sales Director for the National Market. “It is an evolution of DWDM technology that brings greater flexibility and efficiency to data transmission over optical networks, allowing adaptation to different scenarios as well as to future technologies,” he adds.
With Padtec’s ROADMs featuring FlexGrid technology, Ampernet can configure channels for local add/drop in a station or node, as well as adjust channel width according to the transponder technology in use: 100 GHz channels for the TM800G transponder or 150 GHz channels for the TM2400G-NK, for example. The TM800G is already being used by the company in its networks, enabling up to 400 Gb/s per channel. In addition, other equipment such as the TM2400G-NK and routers are currently undergoing certification by the provider. With this investment, Ampernet’s network is ready to support channels of 800 Gb/s or even 1.2 Tb/s with state-of-the-art optical transmission technology and future higher-capacity generations.
