LightCounting releases Mega Datacenter Optics Report

Investments by Cloud companies in mega datacenters and supporting networking infrastructure have created a new and very dynamic segment in the optical components and modules market. This report from LightCounting offers an in-depth look at the development of this new market in 2010-2017 and its potential growth in 2018-2023. The database provided with the report presents detailed sales projections of more than 50 product categories of Ethernet optical transceivers, DWDM optics, Active Optical Cables (AOCs) and Embedded Optical Modules (EOMs), segmented into three main applications: telecom, enterprise and cloud. The cloud segment includes optics used inside the mega-datacenters of Cloud companies as well as in the networks connecting the datacenters (known as the data center interconnect, or DCI segment).

LightCounting estimates that sales of Ethernet transceivers to Alibaba, Amazon, Facebook, Google and Microsoft accounted for close to 60% of all Ethernet transceivers sold for applications in mega datacenters in 2017. Their share is projected to peak at 64% in 2020, but it will decline after that. We expect that several other Cloud companies will challenge the dominance of the Top 5 in 2021-2023.


Chinese Cloud companies are the best positioned to challenge the dominance of U.S.-based vendors. Alibaba sharply increased its investments into high speed Ethernet optics in late 2017 and early 2018, and it is now included in the Top 5 category. Baidu and Tencent are the best-known Cloud companies in China that are likely to follow Alibaba’s lead in increasing their infrastructure spending. There are several other lesser-known Cloud companies in China that operate networks of datacenters, including Ksyun Cloud, QingCloud, UCloud and SpeedyCloud. Policies of the Chinese government favor the creation of new and the growth of existing Cloud companies in that country. Chinese consumers are adopting many Cloud applications faster than Western consumers, according to analysis presented in the LightCounting report titled “Market for Optics in China”.

Current policies of the U.S. government for imposing new trade barriers will have a negative impact for international expansion of the U.S.-based providers of Cloud services. This will lead to faster growth of local Cloud vendors in many other countries, including India – home to 1.35 billion people. These new national champions will copy the business models of Amazon, Facebook and Google, including investments in local data centers equipped with the latest technologies.

Alibaba, Baidu, and Tencent operate a distributed network of datacenters in many metro areas because of restrictions on building larger facilities in China. Mega datacenters operated by the Western Cloud companies are starting to transform into metro-regional clusters as their strategies evolve. Interconnecting these distributed facilities will require a lot of high-bandwidth optics.

Amazon operates 25 datacenters interconnected with 3500 fibers in Ashburn, VA. Facebook expanded its mega datacenters by constructing new facilities in the vicinity of its existing ones. Microsoft announced its intention to build more metro and regional datacenters to reduce the time required for planning new facilities, along with achieving several other benefits. Cloud companies are also starting to invest in edge datacenters to position content and services closer to their end users.

The direct impact of Cloud companies on the market for optical components and modules is substantial, but the Cloud companies’s influence on the market spreads far beyond billions of dollars spent on purchases of optics each year. Amazon, Google, Microsoft and more recently Facebook and Alibaba have shaken up the industry by accelerating innovations in technology, disrupting supply chain practices and challenging industry standards.

Impact of these trends on the market for optical Ethernet and DWDM transceivers, Active optical Cables (AOCs) and Embedded Optical Modules (EOMs) is discussed in the report.

3D Sensing for Self-Driving Cars Reaches the Peak of Inflated Expectations

LightCounting releases a new report addressing illumination in smartphones and automotive lidarIn 2019, the market for VCSEL (vertical cavity surface-emitting laser) illumination in smartphones will exceed $1.0 billion – now nearly triple the size of the market for communications VCSELs. That’s quite remarkable for a market that didn’t exist three years ago.3D sensing in smartphones felt like an overnight sensation, but the technology foundations were laid down years ago with Microsoft’s Kinect – a motion-sensing peripheral for gamers released in 2010 but discontinued in 2017 after lackluster sales. Lumentum supplied lasers to the Kinect almost a decade before the iPhone opportunity emerged; the company was ready to profit from the iPhone X opportunity when Apple decided to launch 3D sensing for facial recognition in September 2017.

If all technologies follow the Gartner Hype Cycle, shown in the Figure above, then 3D sensing in smartphones is now moving up the slope of enlightenment. Android brands raced to add 3D sensing to their flagship phones in 2018 – the Xiaomi Mi8 Explorer and Oppo Find X phones were first – although these only sold in single digit million quantities. Huawei also brought out new phones with 3D sensing, but the ongoing U.S. export ban on the Chinese company must be hurting the company’s traction outside China. Apple continues to dominate the market as all new iPhones released by Apple since 2017 have included 3D sensing on the front of the phone. Apple is expected to introduce 3D sensing for ‘world-facing’ applications in 2020, which adds another laser chip to every phone.

Last year illumination for lidars were not included in our market forecast since LightCounting considered it unlikely that lidar would penetrate the consumer market to any great extent over the forecast period. All indicators now point to a market for lidar illumination ramping up in 2022 and beyond. Optical components firms are now shipping prototypes and samples of VCSELs, edge emitters and coherent lasers to customers developing next-generation lidar systems – many of them building on their expertise in illumination for optical communications and smartphones.

As was the case with smartphones, the foundations for lidar technology were laid down much earlier – in this case with the DARPA Challenge 2007, where the winning vehicle used a 64-laser lidar system from Velodyne Acoustics (now Velodyne Lidar). Lidar is considered by the majority of the industry to be an essential part of the sensor suite required for autonomous driving, helping the vehicle to navigate through the environment and detect obstacles in its path. The first commercial deployments have begun. In Germany, lidar on the Audi A8 enables the car to drive itself for limited periods under specific conditions. In Phoenix, Arizona, you can hail a ride in a Waymo robotaxi.

Investor enthusiasm for lidar is undeniable with nearly half a billion dollars invested in lidar start-ups in 2019 according to our analysis of publicly available investment data. Notable deals include $60 million for U.S. company Ouster in March, Israel’s Innoviz Technologies Series C round of $132 million in the same month, and $100 million for U.S.-based Luminar Technologies in July. Interestingly, these examples illustrate the variety of lidar approaches: each company is building a different type of lidar based on a different wavelength: 850nm for Ouster, 905nm for Innoviz and 1550nm in the case of Luminar. There’s an open technology battle and they can’t all be winners.

The automotive lidar market seems to be close to the peak of ‘inflated expectations’. It’s easy to understand why. The automotive industry is enormous, with nearly 100 million vehicles (including trucks) produced annually. Players like Baidu, GM Cruise and Waymo are backed by deep corporate pockets, and new entrants like Aurora and Pony.ai are attracting hundreds of millions in investment. Intel’s $15.3 billion purchase of Mobileye in 2017 was also directed at autonomous driving. Sensor company AMS is in a $4.8 billion battle to acquire German semiconductor lighting firm Osram with its eye firmly on lidar.

However, signs indicate that the descent into the trough of disillusionment could have already begun. Waymo has yet to roll out its robotaxi services more widely – and this summer admitted that its vehicles needed more testing in the rain. GM Cruise has delayed launch of commercial services for self-driving cars beyond 2019 and is reluctant to commit to a new timescale, with its CEO Dan Ammann observing that safety is paramount; automotive is not an industry where you can “move fast and break things” he said. A casualty of the slow pace was optical phased array lidar developer Oryx Vision, which closed its doors in August and started to hand money back to investors.

While lidar is being deployed commercially today, prices are not conducive to mass production, and there are open questions around regulation, safety, ethics and consumer acceptance. Do local laws prohibit self-driving cars? Will they really be safer than humans? Who is responsible for a crash? LightCounting remains skeptical about the pace of adoption of autonomous vehicles, but will be watching the market closely and with optimism.
