Nokia announced it has achieved a major network capacity with Elisa while preparing the operator's network for the future. Through a live commercial trial, the companies are proving the world's first 1T (terabit) clear-channel interface deployment to efficiently scale Elisa's network to support new applications and access technologies. The exponential demand for connectivity and bandwidth driven by cloud computing, video streaming, AI, IoT and 5G, coupled with changing internet traffic patterns among consumers, home workers and businesses is pushing capacity limits of communication service provider (CSP) networks.

As CSPs look to combine gigabit capable fixed and wireless access technologies, the IP networks that carry this broadband traffic must scale in lockstep. Most networks are still operating a multitude of 100GE ports, with 400GE on the horizon. Nokia's trial with Elisa is proving out terabit interfaces.

Elisa upgraded some of its Nokia 7950 Extensible Routing System (XRS) nodes with 1T interfaces powered by Nokia's FP4 chipset, the industry's first terabit capable routing silicon. The new FP4 terabit linecard supports two 1T ports and demonstrated deployment readiness by carrying live traffic on Elisa's network. Besides a 10x boost in capacity, terabit links simplify operational complexity and overheads by avoiding the need to distribute terabit flows on high capacity routes over multiple lower rate interfaces in link aggregation groups.
