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.

Real-time visibility makes optical networking smarter

Part 1: Ciena's Liquid Spectrum

Systems vendors are making optical networks smarter. Their latest equipment, combining intelligent silicon and software hooks, can measure the status of the network and enable dynamic network management.

Ciena recently announced its Liquid Spectrum networking product while Infinera has launched its Instant Network. Both vendors exploit the capabilities of their latest generation coherent DSPs to allow greater network automation and efficiency. The vendors even talk about their products being an important step towards autonomous or cognitive networks.

Infinera goes multi-terabit with its latest photonic IC

In his new book, The Great Acceleration, Robert Colvile discusses how things we do are speeding up.

In 1845 it took U.S. President James Polk six months to send a message to California. Just 15 years later Abraham Lincoln's inaugural address could travel the same distance in under eight days, using the Pony Express. But the use of ponies for transcontinental communications was shortlived once the electrical telegraph took hold. [1]

The relentless progress in information transfer, enabled by chip advances and Moore's law, is taken largely for granted. Less noticed is the progress being made in integrated photonic chips, most notably by Infinera.

Next-generation coherent adds sub-carriers to capabilities

Briefing: DWDM developments

Part 2: Infinera's coherent toolkit 


Source: Infinera

Infinera has detailed coherent technology enhancements implemented using its latest-generation optical transmission technology. The system vendor is still to launch its newest  photonic integrated circuit (PIC) and FlexCoherent DSP-ASIC but has detailed features the CMOS and indium phosphide ICs support.

The techniques highlight the increasing sophistication of coherent technology and an ever tighter coupling between electronics and photonics.

Ovum Q&A: Infinera as an end-to-end systems vendor

Infinera hosted an Insight analyst day on October 6th to highlight its plans now that it has acquired metro equipment player, Transmode. Gazettabyte interviewed Ron Kline, principal analyst, intelligent networks at market research firm, Ovum, who attended the event.    

 

Q. Infinera’s CEO Tom Fallon referred to this period as a once-in-a-decade transition as metro moves from 10 Gig to 100 Gig. The growth is attributed mainly to the uptake of cloud services and he expects this transition to last for a while. Is this Ovum’s take?  

Ron Kline, OvumRK: It is a transition but it is more about coherent technology rather than 10 Gig to 100 Gig. Coherent enables that higher-speed change which is required because of the level of bandwidth going on in the metro.

We are going to see metro change from 10 Gig to 100 Gig, much like we saw it change from 2.5 Gig to 10 Gig. Economically, it is going to be more feasible for operators to deploy 100 Gig and get more bang for their buck.

ECOC 2015: Reflections

Gazettabyte asked industry executives what trends and highlights they noted at the recent European Conference on Optical Communication (ECOC) event, held in Valencia. Here are three views.

ECOC was a big show and included a number of satellite events, such as the 6th European Forum on Photonic Integration, the 3rd Optical Interconnect in Data Center Symposium and Market Focus, all of which I attended. So, lots of information to digest. 

My focus was mainly on data centre optical interconnects and photonic integration.

Verizon tips silicon photonics as a key systems enabler  

Verizon's director of optical transport network architecture and design, Glenn Wellbrock, shares the operator’s thoughts regarding silicon photonics.

 

Part 3: An operator view

Glenn Wellbrock is upbeat about silicon photonics’ prospects. Challenges remain, he says, but the industry is making progress. “Fundamentally, we believe silicon photonics is a real enabler,” he says. “It is the only way to get to the densities that we want.”

Wellbrock adds that indium phosphide-based photonic integrated circuits (PICs) can also achieve such densities.

But there are many potential silicon photonics suppliers because of its relatively low barrier to entry, unlike indium phosphide. "To date, Infinera has been the only real [indium phosphide] PIC company and they build only for their own platform,” says Wellbrock.
