Nokia announced significant enhancements to its 1830 Photonic Service Switch (PSS) portfolio, including the introduction of a new Photonic Service Engine version 2 (PSE-2) chip that enables the platform to double wavelength capacities and wavelengths per fiber. The new electro-optic chipset PSE-2 is available in two versions:
- the PSE-2 Super Coherent (PSE-2s) provides the ultimate in performance and flexibility for applications with very high traffic demands and potentially challenging distance requirements. It can be programmed 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 – including the industry’s first 400G single carrier, the first 200G long haul and the first 100G ultra-long haul. The PSE-2s lowers cost per bit per kilometer by maximizing capacity for every distance, while using 50 percent less power.
- the PSE-2 Compact (PSE-2c) is optimized 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 portfolio update includes:
- a new 1830 PSS-24x packet/OTN multilayer switching platform powered by a new Nokia-designed Transport Switching Engine (TSE) chipset. Nokia said that by combining a TSE-powered switch fabric with PSE-2 coherent interfaces, the 1830 PSS-24x offers 9.6 terabits of switching per half-rack shelf, scalable to 48 terabits per rack.
- a new 1830 PSS 500G DWDM Muxponder, powered by the PSE-2s and its variable modulation capabilities, offers operators investment protection for their 1830 PSS platforms with an instant capacity upgrade, carrying as many as five 100G services per line card. The 500G line card is available and being delivered to customers now.
- an expanded Wavelength Routing solution that supports the L wavelength band, thereby doubling the number of wavelengths per fiber. By integrating PSE-2 powered interfaces and Colorless, Directionless, Contentionless, with Flexgrid (CDC-F) technology, the 1830 PSS Ultra-Wideband Wavelength Routing solution becomes the industry’s first C+L band CDC-F system, giving operators unprecedented programmability in the photonic layer.
Sam Bucci, head of optical networking at Nokia, said: “When we introduced the industry’s first single carrier 100G solution in 2010 we became a leader in optical network transformations, a position that was further solidified when we released the first programmable 100G/200G line card. With the launch of the PSE-2, our 500G Muxponder and the 1830 PSS-24x, we are again at the forefront of innovations, leading the way to 100G client services being the currency of modern optical networks. Thanks to the optical innovations of Nokia Bell Labs we are able to keep operators ahead of today’s aggressive bandwidth demand curve.”
