Bangladesh Infrastructure service provider Summit Communications has signed a deal with Juniper Networks to upgrade its core optical network to 400G in anticipation of a surge in traffic demand once 5G is commercially launched in the country.

Under the deal announced by Juniper on Wednesday, Summit will deploy Juniper’s PTX10000 Series packet transport routers equipped with 400G coherent optics. Juniper said the routers enable Summit to make a seamless transition to a converged optical routing architecture that delivers high-speed data transmission over long distances to its PoPs in Bangladesh while maintaining high reliability.

Summit Communications chief network architect Md. Farrukh Imtiaz said the 400G solution will “establish a more robust foundation, delivering the performance, scalability and operational efficiencies essential to our network.”

Summit Communications MD and CEO Arif Al Islam said that the company has made “tremendous progress” in rolling out networking infrastructure services to mobile operators and ISPs in Bangladesh, but that it needs to adopt innovative new networking solutions to keep up with current and future demand for mobile, internet and digital services, especially with 5G coming down the pipeline.

“[Juniper’s] solutions will continue to play an integral role in our network, ensuring that we provide cutting-edge 5G connectivity and services for our customers guaranteeing fast, reliable, ultra-low latency services along with adaptation of network slicing and segment routing,” he said in a statement.

State-owned telco TeleTalk has been trialing 5G since 2021, while Grameenphone and Robi Axiata have launched their own trials since then. In 2022, Grameenphone, Robi Axiata, Banglalink and Teletalk paid a combined US$1.2 billion for 5G spectrum in an government auction. However, none have commercially launched 5G thus far, opting instead to focus on expanding their 4G networks first.
