The optical interconnect market is anticipated to grow at a CAGR of about 15% over the forecast period 2020 to 2025. Optical interconnect will play an increasing role in the future of intelligent networks. The transport of information over distances as small as centimeters benefits from the multi-terabit capacity of optical fibers when data rates exceed 10 Gb s?1. Presently, directly modulated VCSEL arrays, parallel fiber ribbons, along with detector arrays, are highly being applied to optical backplane capacity issues. In the future, additional higher functionality is highly expected as an emerging trend for optical interconnects, which includes features such as cross-connect switches and data packet routing in the optical domain.
- The growing demand for communication bandwidth is expected to drive the market. Due to the emergence of a large number of new services in different types of communications and their value-added entities, the demand for bandwidth has gone up more than ever before. Optical interconnect drive it possible in providing more bandwidth and bring great advantage to computing performance as compared to electrical interconnects.
- With optics, over the next decade, it is believed that the energy-requiring for cross-chip communication would approach less than 0.5 pJ b?1 and to 0.1 pJ b?1 for communication such as off-chip communication technology. By utilizing the ability to move data affordably, both the power consumption and the total cost for such future multicore processor systems are expected to be reduced with improving bandwidth.
- The demand for mobile cloud computing is also expected to aid the growth of the market. Future networks set to provide a broad range of services over a multitude of technologies that carries a high range of traffic profiles. According to Cisco, the distribution of global cloud mobile traffic increases approx 90% in 2019 compared to 2018, having a distribution of 88%. The emerging mobile cloud computing applications impose numerous challenges on network operators to enable on-demand service provisioning. On handling the rising demands, wired and wireless networks, together with IT infrastructures, need to be part of a converged platform. Flexible and programmable optical networks integrate and merge IT and wireless technologies effectively and efficiently. The use of time shared optical network (TSON) for the interconnection of wireless access networks, and IT resource provides a path for the growth of the market.
- Further, the impact of Covid-19 has affected the market growth due to low demand by consumer segments in the automotive and consumer electronics segment. Players such as 3M are currently manufacturing medical products to assist in the fight of Covid-19. 3M has doubled production of N95 respirators to 1.1 billion per year at its global manufacturing facilities, including in the U.S., Asia, and Europe. This has led to the reduced manufacturing for optical interconnect cables.
- However, as the ability to work from home has become an absolute necessity, a player such as Nexcom (Taiwan) announced in May 2020, it can now help telecom providers and data centers across the world to virtualize and expand capacity. For meeting current network demands for faster speeds, the NC 220FMS3 module provides a PCIe3.0 x16 interface and two QSFP28 ports, each supporting 100Gb/s Ethernet connectivity. The module provides high-speed connectivity without any packet loss. The 100 G optical transceivers (providing 100Gb/s ethernet), their form factor type, and standard are developed according to the cost and power consumption, which are regarded as the main drive in the development for interconnect market, which potentially provides the demand of optical interconnect.
Key Market Trends
Data Center to Account for High Market Share
- Current data center networks, which are based on electronic packet switches, experiences an exponential increase in network traffic due to cloud computing development. Optical interconnects emerged as a promising alternative that offers high throughput, low latency, and reduced power consumption.
