Ciena brings data analytics to optical networking

• Ciena's WaveLogic Ai coherent DSP-ASIC makes real-time measurements, enabling operators to analyse and adapt their networks.     
• The DSP-ASIC supports 100-gigabit to 400-gigabit wavelengths in 50-gigabit increments. 
• The WaveLogic Ai will be used in Ciena’s systems from 2Q 2017.  

Ciena has unveiled its latest generation coherent DSP-ASIC. The device, dubbed WaveLogic Ai, follows Ciena’s WaveLogic 3 family of coherent chips which was first announced in 2012. The Ai naming scheme reflects the company's belief that its latest chipset represents a significant advancement in coherent DSP-ASIC functionality.  

Helen XenosThe WaveLogic Ai is Ciena's first DSP-ASIC to support two baud rates, 35 gigabaud for fixed-grid optical networks and 56 gigabaud for flexible-grid ones. The design also uses advanced modulation schemes to optimise the data transmission over a given link.

Perhaps the most significant development, however, is the real-time network monitoring offered by the coherent DSP-ASIC. The data will allow operators to fine-tune transmissions to adapt to changing networking conditions.

Cyan's stackable optical rack for data centre interconnent

Demand for high-capacity links between data centres is creating a new class of stackable optical platform from equipment makers. Cyan has unveiled the N-Series, what it calls an open hyperscale transport platform. "It is a hardware and software system specifically for data centre interconnect," says Joe Cumello, Cyan's chief marketing officer. Cyan's announcement follows on from Infinera, which detailed its Cloud Xpress platform last year.

"The drivers for these [data centre] guys every day of the week is lowest cost-per-gigabit"
