Nokia PSS promises to quadruple optical fiber capacity
Telecom network maker Nokia has expanded its 1830 Photonic Service Switch (PSS) promising to quadruple optical fiber capacity to more than 70 terabits per second.

Nokia said the new 1830 PSS-24x is the world’s most scalable packet-OTN switch, providing up to 48 terabits of capacity per rack.

500G DWDM line card provides investment protection for 1830 PSS customers with an instant upgrade to 500G of flexible bandwidth for delivery of 100G services.

The enhanced 1830 PSS, centered around the Photonic Service Engine version 2 (PSE-2) from Nokia Bell Labs, doubles wavelength capacities and wavelengths per fiber, giving operators a platform to efficiently deliver the 100G transport services.

# to quadruple optical fiber capacity to more than 70 terabits per second
# providing up to 48 terabits of capacity per rack
# PSE-2s lowers cost per bit per kilometer
# uses 50 percent less power

Ovum says the adoption of 100G router ports for the interconnection of data centers and metro and backbone applications is driving the need for operators to migrate from 10G client services to 100G to keep pace with escalating transport requirements.

Ron Kline, principal analyst, Intelligent Networks at Ovum, said: “Service provider adoption of 100 Gigabit Ethernet is expected to drive growth of Core IP/MPLS routers to roughly $3.6 billion by 2020. This, in turn, will fundamentally transform operators’ networks as they look for solutions to handle this massive capacity increase in increments of 100G.”

Nokia is offering PSE-2 in two versions.

“While each of the PSE-2 advancements is important on its own, it is really the flexible combination of features – covering 100G to 200G to 400G and from metro to long haul and ultra long haul applications,” said Sterling Perrin, senior analyst at Heavy Reading.

Users can program the PSE-2 Super Coherent (PSE-2s) with seven unique modulation formats to support optimized 100G to 500G transport wavelength capacities, and distances for applications ranging from metro to ultra-long haul.

The PSE-2s lowers cost per bit per kilometer by maximizing capacity for every distance, while using 50 percent less power.

Nokia has optimized the PSE-2 Compact (PSE-2c) for 100G DWDM applications where density, space and low power are paramount, including metro access and aggregation networks. The PSE-2c design creates more compact line cards that support “pay as you grow” pluggable optics, while consuming 66 percent less power.

The 1830 PSS-24x offers 9.6 terabits of switching per half-rack shelf and is scalable to 48 terabits per rack. This gives operators a new level of 100G service density, efficiency, and resiliency while using 50 percent less space and power than current generation packet/OTN switches.

Daniel Melzer, CTO of DE-CIX, said: “By operating the world’s leading Internet exchange with peak traffic of more than 5 Terabits per second, DE-CIX is seeing an increased need to dynamically interconnect 100G router ports to handle our changing bandwidth needs.”
