Infinera inches closer to cognitive networking

Part 2: Infinera’s Instant Network

The second and final part as to how optical networking is becoming smarter

Infinera says it has made it easier for operators to deploy optical links to accommodate traffic growth.

The system vendor says its latest capability, known as Instant Network, also paves the way for autonomous networks that will predict traffic trends and enable capacity as required.

The latest announcement builds on Infinera’s existing Instant Bandwidth feature, introduced in 2012, that uses its photonic integrated circuit (PIC) technology.

Instant Bandwidth exploits the fact that all five 100-gigabit wavelengths of a line card hosting Infinera’s 500-gigabit PIC are lit even though an operator may only need a subset of the 100-gigabit wavelengths. Using Instant Bandwidth, extra capacity can be added to a link - until all five wavelengths are used - in a matter of hours.

The technology allows 100-gigabit wavelengths to be activated in minutes, says Geoff Bennett, director, solutions and technology at Infinera (pictured). It takes several hours due to the processing time for the operator to raise a purchasing order for the new capacity and get it signed off.

Infinera unveils first platforms using its latest PIC & DSP  

  • The Cloud Xpress 2 platform for data centre interconnects packs 1.2 terabits in a 1 rack unit (1RU) box.  
  • Infinera has also unveiled two DTN-X XT 'meshponder' platforms that aggregate client signals and offer sliceable transponder functionality that delivers wavelengths to multiple destinations. 
  • The company also announced an open flexible grid line system that supports the C and L bands 
  • Three of the top four US internet content providers are Infinera customers.

Infinera has started to unveil its platform portfolio based on its Infinite Capacity Engine that combines the company's latest-generation photonic integrated circuit (PIC) and coherent DSP-ASIC technology.

The first platform using the technology is the Cloud Xpress 2, Infinera second-generation data centre interconnect platform, was unveiled in September. More recently, it has added two DTN-X meshponder platforms - the XT-3300 and the XT-3600 - as well as upgrading two of its existing DTN-X platforms.

Infinera introduces flexible grid 500G super-channel ROADM

Infinera has unveiled a flexible grid, reconfigurable optical add/drop multiplexer (ROADM) to complement its DTN-X optical networking platform.

"The FlexROADM will open up the Tier-1 operators in a way Infinera has not been able to do before," says Dana Cooperson, vice president, network infrastructure at market research firm, Ovum. "The DTN-X was necessary but not sufficient; the ROADM is the last piece."
