The fastest networks just got faster
The Alcatel-Lucent 400G Photonic Service Engine (PSE) is the first-ever commercially available electro-optics chip capable of driving traffic up to 400 gigabits per second (Gb/s). Versatile and scalable, it dramatically boosts the performance of 100G networks today—and lays the foundation for 400G transport down the road.
Built on in-house Bell Labs research and extensive field experience with 100G deployments, the 400G PSE is designed specifically for our 1830 Photonic Service Switch. It delivers 4X the speed of 100G and increases the capacity of today’s transport networks, while improving efficiency and better addressing the massive growth of broadband traffic.
4X the speed
The 400G PSE accelerates network speeds fourfold and delivers the highest possible performance per wavelength at 100G. It has the ability to pack more wavelengths into every fiber through waveform engineering, with the potential to increase spectral efficiency by as much as 33 percent.
Performance with no trade-offs, reach without regeneration
Keep up with customer demand for broadband, mobile data and cloud-based services—no matter how high that demand climbs. The Alcatel-Lucent 400G PSE offers a fourfold increase in density over current 100G solutions. That means you can scale quickly without expanding your footprint. And it offers a direct path to 400G when you’re ready to evolve again. The 400G PSE also extends your reach, supporting metro, regional, long-haul and ultra-long-haul transmission—beyond 3,000 kilometers without regeneration.
Boost efficiency. Manage TCO.
Minimizing space and power requirements, the Alcatel-Lucent 400G PSE lets you evolve your network without costly reengineering. It’s backward compatible with current 100G systems—whether newly lit or brownfield fiber photonic lines—at 10G, 40G and 100G. It features a market-first transmit digital signal processor (DSP), enabling wave shaping to improve tolerance to nonlinearlities. The 400G PSE also cuts power consumption by 33 percent per gigabit of transport. And it can be tuned to optimize performance per route—for example, by dialing pre-compensation up or down to address chromatic dispersion and extend reach.
Built on Bell Labs innovation
The 400G PSE chip furthers the well-established legacy of innovation at Bell Labs. It combines new modulation formats with coherent technology and advanced digital signal processing (DSP) to pack more information into every optical transmission. The newly developed transmit DSP can shape wavelengths—allowing better spectral efficiency, better tolerance to nonlinearity and improved noise reduction. The 400G PSE also features ultrafast digital-to-analog and analog-to-digital converters, powerful DSP-based forward-error correction and a host of other advancements to deliver the best possible performance and versatility.
"When it was first introduced, coherent optical processing technology was a big differentiator in the high speed optics market. Now simply having coherent processing is no longer enough. Alcatel-Lucent is one of only two vendors that have been shipping 100G coherent commercially for over a year and it is the market leader through 2011. In addition, the company is the only vendor with an integrated IP-optical solution for 100G and now a clear path to 400G. Alcatel-Lucent has raised the bar considerably for competitors just bringing 100G coherent to market. The 400G PSE chipset enables significant advances in network speed, efficiency and performance and lays the foundation for tomorrow’s ultra-high performance public and private networks."

"Alcatel-Lucent's next generation coherent optical engine exemplifies the coupling of Bell Labs advanced research and the company's 100G commercial market experiences. The PSE may well be the first commercial 400G chipset, but, just as significantly, it will improve the economics and performance of 100G systems - broadening and accelerating 100G market adoption."
