The Communication and sensor society is a reality. According Cisco® Visual Networking Index (VNI) Global Mobile Data Traffic Forecast  Global mobile data traffic grew 63 percent and the number of mobile devices and connections grew to 8.0 billion in 2016. More and more things get connected; cars, trains as well as wearable devices. Video is still the main traffic driver with video traffic accounting for 60 percent of total mobile data traffic in 2016, . In figure 1 you can see some examples of actual usage need for some New IoT Devices.

It is noticeable that the communication and sensor society is driving some big trends. One of these trends are the hyper scale data centers  that use massive amounts of fiber connections within the data center. Hyperscale data centers are projected to number 485 by 2020 . By 2020, 92 percent of workloads will be processed by cloud data centers versus only 8 percent by traditional data centers. Driven by the Internet of Things, the total amount of data created (and not necessarily stored) by any device will reach 600 ZB per year by 2020, up from 145 ZB per year in 2015.

CST Global which is a wholly owned subsidiary of Sivers IMA offers for example Vertical Cavity Surface Emitting Laser (VCSELs) which are essential building block of modern, optical, communication systems. VCSELs offer a high bandwidth, power-saving and low-cost solution for links used within hyper scale data centers and high-performance computing. Sivers IMA believe hyper scale data centers is a high growth market, in the same way wireless mmWave multigigabit is another very interesting growth market we address. Hence being able to offer VCSELs for optical communication systems is very compelling and exciting, and we are now addressing several growth trends within the communication and sensor society.
