"Now we are in the second wave of photonics, Suresh Venkatesan explains. It is bigger and more sustainable than the first wave, because it is driven primarily by the needs of consumers and corporate users. 2015 saw more than 1.6 billion smartphones worldwide. 1.8 billion photos are uploaded every day, and, according to a Cisco estimate, in 2018 we will stream one million video minutes per second through the Internet. More and more companies are storing their data „in the cloud“, i.e. on the computers of cloud providers. These gargantuan amounts of data are driving the demand for ever higher throughputs in data centers and for additional data centers."

"Cost is top priority for data center operators. POET Technologies intends to unfold a huge operating cost reduction potential with its active optical cables (AOC). Short and very short distances are still in the domain of copper cables today and they are relatively energy hungry. Optical cables are carrying data in the form of light signals. However, while consuming much less power, they are simply too expensive – or the optical cables of today are. POET’s optical cable, however, will cost not much more than a copper cable and still provides the user with all the benefits of optical cables. „What you have to sell is what the market needs“, Venkatesan quotes a typical statement from the business. And although POET cables will be much cheaper in sales than other optical cables, they are promising a high return on sales because of their low manufacturing costs."

Cloud traffic will represent 92% of data centre traffic by end of decade, Cisco predicts.

The exponential growth of cloud is set to put never seen amounts of pressure on data centres by the end of this decade.

According to Cisco’s most recent Global Cloud Index, cloud traffic will represent 92% of data centre traffic by 2020, and increase from 2015’s 3.9 zettabytes to 14.1 zettabytes, a rise of 3.7-fold.

In the index it says the rapid growth of cloud traffic “is attributed to increased migration to cloud architectures due to their ability to scale quickly and efficiently support more workloads than traditional data centres”.

Doug Webster, VP of Service Provider Marketing, at Cisco, said: “Powered by video, IoT, SDN/NFV and more, we forecast this significant cloud migration and the increased amount of network traffic generated as a result to continue at a rapid rate as operators streamline infrastructures to help them more profitably deliver IP-based services businesses and consumers alike.”

Cisco has studied the evolution of workloads within the date centre and predicts a CAGR growth of 21% between 2015 and 2020, from 180.9 million last year to 478.8 million in four years. This year, workloads have already increased by about 50 million to 234.9 million.

The report predicts business workloads to grow by 2.4 fold from 2015 to 2020, however, their overall share of data centre workloads will decrease from 79 to 72%.

Consumer workloads are expected to grow faster by 3.5 fold and account for 28% (134.3 million) of total data centre workloads by 2020, compared to 21% (38.6 million) in 2015.

By 2020, database/analytics/Internet of Things (IoT) workloads will account for 22% of total business workloads, compared to 20% in 2015.

Lastly, by the end of this decade, Cisco predicts that video streaming workloads will account for 34% of total consumer workloads, compared to 29% in 2015; social networking workloads will account for 24% of total consumer workloads, compared to 20% in 2015; search workloads will account for 15% of total consumer workloads, compared to 17% in 2015.
