Nokia has declared the world's first 1 terabit clear-channel interface deployment on Elisa's network in a commercial trial, using the Nokia FP4 chipset. Elisa upgraded some of its Nokia 7950 Extensible Routing System (XRS) nodes with 1T interfaces running on the FP4 chipset. The FP4 terabit linecard supports two 1T ports and demonstrated deployment readiness by carrying live traffic on Elisa’s network.
Terabit links improve capacity by ten times and simplify operational complexity and overheads, said Nokia, by avoiding the need to distribute terabit flows on high capacity routes over multiple lower rate interfaces in link aggregation groups.
Nokia said most networks are still operating a multitude of 100GE ports, with 400GE on the horizon. The vendor said the FP4 chipset is the first terabit-capable routing silicon.
Kalle Lehtinen, CTO at Elisa, said the IP routing capability achieved with Nokia enables the operator to leapfrog an 800G progression "that other service providers are only strategising about". This strengthens Elisa’s position as a global 5G leader and gigabit broadband service provider, said Lehtinen.
