Elisa has 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.
Elisa’s live commercial trial is 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 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.

Kalle Lehtinen, CTO at Elisa, said: “Elisa continues its string of world firsts with this record-breaking IP routing capability achieved with Nokia, enabling us to leapfrog an 800G progression that other service providers are only strategizing about.”

Ken Kutzler, vice president of IP Routing Hardware at Nokia, said: “Delivering FP4-based 1T ports in the 7950 XRS is a testament to Nokia’s innovation and drive to push the technology envelope, maximizing investments for customers like Elisa.”
