Market Growth Factors

The​‍​‌‍​‍‌​‍​‌‍​‍‌ worldwide optical interconnect market is mainly fueled by the escalating need for internet services in the sectors of home, business, and industry. The rapid growth of the IT sector along with the advent of big data analytics and the Internet of Things (IoT) intensifies the requirement for data transmission and bandwidth communication of very high capacity. Consequently, this technological change has caused a substantial increase in the worldwide demand for optical interconnect systems that are capable of supporting efficient and fast data communication. 

As semiconductor applications evolve, the need for bandwidth has been met by optical interconnects that provide frequency-dependent loss with a very low value, negligible crosstalk, and a high bandwidth. Besides, they can be considered as a better choice than the conventional technologies for the fulfillment of present data processor performance requirements. In addition, the issue of data centers' energy consumption has become the main factor behind the rise of the market which is driven by the extreme need for enhancement of the bandwidth capacity together with the necessity to reduce power consumption in data center networks for energy-efficient operations. 

Moreover, increasing network traffic originating from both private and government sectors has become a major driver of the demand for optical interconnect devices. These devices are crucial for the effective use of resources while managing cloud computing systems and web applications, which are the backbone of the new digital ecosystems. Since cloud applications enable fast communication and make digital transformation easier, the use of optical interconnects has been increasing at a rapid pace in the information-centric industries.
