The data bus market is projected to grow from USD 15.70 Billion in 2016 to USD 19.47 Billion by 2021, at a CAGR of 4.41% during the forecast period. Intensive electrification in automotive, commercial aviation, and marine sectors, modernization of military aircraft, telematics, and need to reduce Swap specifications are the major factors, which are expected to drive the market globally. There is a positive trend towards adoption of AFDX/ARINC 664 and MIL-STD technologies by market leaders. China, India, Brazil, Russia, and Saudi Arabia are the key countries that are expected to witness an increase in demand for data bus.

Based on protocol, the data bus market has been segmented into ARINC 429/629, CAN, TTP, AFDX/ARINC 429/629, and MIL-STD-1553. The ARINC 429/629 segment is estimated to lead the market in 2016. This growth can be attributed to use of these protocols in major applications, namely marine and aircraft, to achieve high accuracy.

Based on application, the marine segment is expected to lead the data bus market during the forecast period. It is estimated to account for the largest share of the market due to upgradation of old military naval systems, which means integration of new technology into the existing naval systems. Data bus plays a vital role in naval systems as it provides a path for data, and connects all on-board computers and sensors.

Based on component, the cables segment is expected to lead the data bus market during the forecast period. It is estimated to account for the largest share of the market due to technological advancements, and use of fiber optics over copper cables, and lightweight cables to save space and cost.

North America is estimated to account for the largest share of the data bus market in 2016. The growth of the market in North America can be attributed to the growth of the electric car industry due to environmental regulations and green initiatives. Furthermore, the Asia-Pacific market is expected to grow at the highest rate. Rise in defense spending of countries in the Asia-Pacific region is expected to drive the data bus market during the forecast period.

The U.S. and the U.K. are witnessing economic slowdown. The U.S. government has drastically reduced its defense spending. According to the U.S. DoD, in 2015, the country solely accounted for approximately USD 650 billion of the total defense spending. Besides the U.K. and the U.S., the European Union, which is recovering from economic crisis, is mulling over trimming its defense budget. In addition, the life cycle of a data bus varies from 35-45years, after which, a data bus is upgraded. Key players prefer replacing the data bus than upgrading it. Hence, the market for data bus remains stagnant for a long period, thereby restraining the growth of the data bus market.

The data bus market is a diversified and competitive market with a large number of players. Key players in the market are TE Connectivity (Switzerland), Amphenol Corporation (U.S.), Fujikura Ltd. (Japan), Corning Inc. (U.S.)., and Rockwell Collins (U.S.), among others. TE Connectivity is the leading player in the data bus market. The company has presence in 20 countries of America, Asia-Pacific, Europe, the Middle East, and Africa. In 2015, the company’s transportation solutions business accounted for a share of approximately 40% of the data bus connectors market. The company focuses on carrying out innovations for each of its products that are launched in the market.
