Okay, I apologize for the bad pun, but it does seem like the Fiber Optic market is finally trending upward. I attended the OFC/NFOEC Conference in Anaheim in March and although a bit late, I’m glad that April came and I can describe some of the developments. I was impressed with many of the technology, product and market developments on display.

At the top level, this market segment has floundered, directionless for the past several years. After good growth in the middle part of the 2000’s, the overall optical market ran into trouble in 2009 as the global economy faltered. The result was a drop in revenue of about 15%. With the exception of a short-lived spike in 2011, the market has been relatively flat. This behavior is understandable, because upgrading, expanding or initially deploying an optical transport network is a capital-intensive exercise and the uncertain direction of many regional economies only adds to the challenge. The wildcard in this scenario however, is the seemingly insatiable desire to consume data.

We tend to focus on growth in the mobile data consumption that is enabled by the vast array of wireless devices we’ve all grown so dependent on, but that’s not the whole story. As I am fond of pointing out, even with mobile data roughly doubling every year from 2009 to 2016, it will only account for roughly 10% of the total in 2016. The other portion of data consumption comes from Internet, high-speed broadband, CATV and enterprise data applications. Even with the backdrop of a still uncertain economy, it is becoming clear that transport network upgrades are essential to ensure future data increases are feasible.

It appears operators are finally committing the capital resources and this looks likely to set up the overall optical market for steady future growth. At the component level, another interesting trend I observed is the rapid conversion to higher capacity networks. It appears 10Gbps systems are the workhorse of the network, with lower capacity systems all but disappearing. Another thing that seemed clear was that while 40Gbps systems will grow, they won’t represent as big an opportunity as originally thought. There are currently four modulation schemes used for these networks: optical duo binary, DPSK, differential quadrature phase-shift keying (DQPSK) and dual-polarization QPSK or DP-QPSK. While this lack of standardization allows suppliers to differentiate their designs, it does not allow for economies of scale and the cost reduction standardization usually entails. At the same time, the cost of 10Gbps systems has been dropping quickly. These factors seem to be leading operators to consider jumping directly from 10Gbps to 100Gbps networks, skipping 40Gbps in the process. It appears from the Marketing presentations and the products I saw, that 100Gbps system will see the fastest growth, by far! For more information on growth rates, segmentation, quantities and market values for optical transceivers, please look at Capacity Requirements Driving Fiber Optic Market.

The other big topic at the show was silicon photonics. This idea seems to divide the audience into two distinct and passionate camps. One says, “we’ve been hearing this now for years, but where are the production products?” The other camp is more than ready to discuss the benefits of silicon CMOS processes for cost and power reduction. One thing that appears to be different from the past is the dramatic increase in enterprise applications and “big data”. As server farms grow, so does the need for fast, cheap, low power, short-reach connections. This need seems very well suited to the capabilities of silicon photonics. While the technology doesn’t appear to meet the needs of every application, there is certainly a lot of development effort and it will be interesting to see how quickly silicon photonic circuits penetrate short-reach enterprise applications. Stay tuned!

In the course of the last month or so, I have had the opportunity to attend CS MANTECH, CTIA Wireless and The Cable Show. Even though these conferences address different industries and different points on the supply chain, it was very interesting to see similar threads running through all three. The conclusion is inescapable: data consumption is the engine that is driving consumer and enterprise devices and networks. These networks, whether wired or wireless, are also becoming increasingly intertwined.

The onslaught of data consumption is not new, Strategy Analytics has been following the dramatic increase for years and most top-level market presentations include some reference to this trend. I think the most succinct explanation of this trend came during a panel session at The Cable Show. Actor, director and writer Edward Burns characterized the current landscape (and I am paraphrasing here) as one of access not ownership. This was fascinating to me because Mr. Burns is not in the wireless or wired broadband industry, but he realizes the importance of the network and how consumers access his craft. It also goes a long way toward explaining the demise of “big-box” electronics and audio stores and the growth of audio and video streaming services. It also bodes well for the continued growth of the broadband industry since the high-speed broadband networks enable access.

On the convergence front, one of the big announcements at The Cable Show was that US MSOs Comcast, Time Warner Cable, Cablevision Systems, Bright House Networks and Cox Communications will allow their broadband subscribers to connect to the Wi-Fi networks of any of the companies in this agreement. This combined network will total more than 50,000 hot spots and is again interesting from several fronts. First, it shows the commitment cable companies have made toward having a wireless component to their networks. This is being done with an eye toward maintaining the “broadband experience” for customers who are nomadic outside of their homes. It also shows the concern about wireless broadband capturing share of the total broadband market.

There were presentations from CEOs of major wireless, cable and device companies that were upbeat about the trends in their respective industries. Universally, the drivers for this optimism were increasing data consumption and the advances in the networks and devices to support this consumption. Most, however, also sounded a cautionary note about spectrum availability for the wireless industry and the most efficient way to increase spectrum for the wired industry. Addressing these issues will provide both opportunities and challenges for device, equipment and network manufacturers and will likely determine the trajectory of future growth.

It has been a very lively past few weeks. It is clear the growth engine in the compound semiconductor industry is still firing on all cylinders and convergence is occurring in all segments of the electronics industry. Please keep an eye out for more detailed summaries of the individual conferences in the coming weeks.

Consumer demand for new services, the global digital transition, new technologies and a recovering economy are driving strong growth in CATV network infrastructure. No longer used strictly for video, CATV network infrastructure has become the backbone for the "triple-play" of voice, video and data services offered by cable and telephone service providers. Strategy Analytics forecasts the market for MMIC and hybrid amplifiers in CATV infrastructure will grow at a 10% CAAGR to reach $227 million in 2014. We believe performance and cost benefits will continue to make GaAs-based amplifiers attractive and this technology will grow at twice the market rate. The use of GaAs in lower power MMIC and high power "hybrid equivalent" applications will erode silicon market share.  We forecast GaAs hybrid and MMIC amplifiers will account for revenue of more than $160 million by 2014. As fiber moves deeper into the traditional hybrid fiber coax (HFC) network, more component companies are investigating the performance advantages GaN amplifiers can provide. We have forecast that GaN amplifiers will enter the market in 2010 and this is being borne out by recent product announcements from companies like RFMD. We believe this market will grow rapidly to reach nearly $18 million in 2014. Clients can access the latest reports and data models outlining these forecasts: CATV Infrastruture Amplifier Market: 2009 - 2014 CATV Infrastructure Amplifier Market (Data Table)

Dr David Allstot from the University of Washington kick-started the 2010 IEEE Radio Frequency Integrated Circuits Symposium with a review of the challenges and ongoing research into CMOS power amplifiers for use in the cellular radio front-end. Highlighting the energy consumption and CO2 emissions from cellular handset usage, Dr Allstot emphasized the need for more efficient PAs as continued motivation for development of CMOS PA technologies.  Research into CMOS PAs has been ongoing for around 20 years, with current designs achieveing around 1W power outputs and up to 60% PAE. The performance of typical power amplifier PAs including Class A, B and E were highlighted, and then put into context with the demands of current networks which place greater importance on PAs operating backed off from peak power with schemes such as 64QAM resulting in probability distributions that translate into actual efficiencies of only 5%.  Dr Allstot provided examples of digital PAs comprising multiple PA cells and power combining techniques that have been put forward to address these issues, and highlighted the potential for Class G power PAs that feature a hump-shaped curve with the first peak aligning with probability distribution curves of a 64QAM spectral signal and offering the potential for efficiencies as high as 24%.  While these results are promising, Strategy Analytics still sees a gap in performance capabilities between GaAs and CMOS PAs which is compounded by cellular handset requirements continuing to evolve. This translates into a moving target that places greater emphasis on linearity, efficiencies and peak-to-average ratios (PAR) and in our opinion will continue to favour the capabilities offered by compound semiconductor technologies.  Nevertheless, the pervasive nature of RF technology will open up doors for CMOS and SiGe PAs, while also continuing to provide growth the compound semiconductor technologies, and this was highlighted by the second plenary talk, given by Gregory Waters of Skyworks Solutions Inc.  Mr Waters provided an overview of how the growth in the cellular handset market has transformed the RF industry into a mainstream technology with future trends pointing to greater pervasive use of RF in multiple applications. Smartphones are leading the initial trends towards more complexity in the radio chain which translates into greater content and provides continued growth for the industry.  Video is the primary driver for the RF market moving forwards with social media driving demands for always-on connectivity. This in turn will translate into more RF content going into terminals to meet these needs. Skyworks estimated that average RF content has increased by around 2.5 to 4x the content required when delivering voice-only capabilities.  The different approaches in the cellular front-end to handle these growing needs were highlighted, from multiple PAs through broadband PAs able to tackle high-band and low-band RF chains, to solutions that will cover all bands through a converged solution. This will be coupled with techniques such as envelope tracking and digital predistortion to provide more linear, more efficient RF solutions.  The other key message from Skyworks was that RF technology will become even more pervasive in its application moving forwards, with embedded RF translating to multiple applications, examples including smart metering for utilities, vending machines and passive RF technology for tracking applications.  To serve market needs moving forwards, RF companies will need to continue developing a broad base of technologies that incorporate not only the RF, but also interconnects and packaging   Strategy Analytics sees this pervasiveness as a catalyst that will open doors for Si technologies while the growing complexity needed to serve the always-on connectivity will present continued opportunities for compound semiconductor technologies.
