By David Dollar and Zhi Wang – Two-thirds of world trade now occurs through global value chains that cross at least one border during the production process, and often many borders. As a result, the typical “Chinese product” that the United States imports has a lot of value-added from countries other than China.
Furthermore, in computers and electronics, more than half of China’s exports come from multinational firms operating in China.
U.S. firms are also involved in production chains. Thirty-seven percent of U.S. imports from China are intermediate products used by American firms to make themselves more competitive. Putting tariffs on intermediate products is shooting oneself in the foot. The list of targeted products posted by the United States includes some intermediates, such as aircraft propellers.
Many of the targeted products are consumer goods such as televisions and dishwashers.
What all this means is that tariffs are a very poor instrument for punishing China for any unfair trading practices. Some of the cost will be borne by American consumers; some by American firms that either produce in China or use intermediate products from China; some by firms in countries (mostly U.S. allies) that supply China; and some by Chinese firms (mostly private ones). more>

Coherent optical turns 10: Here’s how it was made
By Bo Gowan – This is the story of how a team of over 100 people in Ciena’s R&D labs pulled together an impressive collection of technology innovations that created a completely new way of transporting data over fiber…and in the processes helped change the direction of the entire optical networking industry.
Back in 2008, many in the industry had serious doubts that commercializing coherent fiber optic transport was even possible, much less the future of optical communications. That left a team of Ciena engineers to defy the naysayers and hold the torch of innovation.
“What we first began to see at Telecom 99 was that we could achieve these high speeds the brute force way, but it was really, really painful,” said Dino DiPerna in an interview. Dino, along with many in his team, were brought on by Ciena as part of the company’s 2010 acquisition of Nortel’s optical business. He now serves as Ciena’s Vice President of Packet-Optical Platforms R&D and is based in Ottawa.
By ‘brute force’ Dino is referring to the traditional time-division multiplexing (TDM) method that had been used until then to speed up optical transmission – basically turning the light on and off at increasingly faster speeds (also called the baud or symbol rate). “But once you start pushing past 10 billion times per second, you begin running into significant problems,” said DiPerna.
Those complexities had to do with the underlying boundaries of what you can do with light. The fundamental issue at hand was the natural spread and propagation of light as it travels along the fiber – created by two phenomenon called chromatic dispersion and polarization mode dispersion, or PMD. As you push past 10G speeds, the tolerance to chromatic dispersion goes down with the square of the baud. Due to PMD and noise from optical amplifiers, a 40 Gbaud stream will lose at least 75% of its reach compared to a 10 Gbaud stream.
This reach limitation had two consequences. First, it meant adding more costly regenerators to the network. Second, it meant that the underlying fiber plant required a more expensive, high-quality fiber to operate properly at 40G transmission speeds. more>

By George Bradt – Most understand the need to follow up and monitor progress on a theoretical level. Yet there are few guidelines to how frequently you should do that. Let me suggest that varies by the nature of what you’re monitoring, ranging from daily or even more frequently for tasks to annually for strategic plans.
Ben Harkin discussed the value of monitoring and reporting in the Psychological Journal. His headline is “Frequently Monitoring Progress Toward Goals Increases Chance of Success” – especially if you make the results public. While he was more focused on personal habits and goals, the findings are applicable to organizational behavior as well.
Here’s my current best thinking on the right frequency of monitoring. The main discriminant is the nature of the work and level of people doing the work with tighter, more frequent monitoring of tactical efforts and looser, less frequent monitoring of more strategic efforts.
- Daily or more frequently – Tasks
- Weekly – Projects
- Monthly – Programs
- Quarterly – Business Reviews, adjustments
- Annually – Strategic/Organizational/Operational processes

What is Fiber Densification?
By Helen Xenos – The term “network densification” is being used more often in relation to wireless network deployments, and more recently, “fiber densification” has become a hot a topic of discussion. So, what exactly is densification?
Densification simply describes the goal or end state of supporting more capacity within the same area or footprint. It is borne from the need of network providers to not only keep up with the increase in bandwidth demand they are seeing, but also grow their competitive edge in delivering a better end user experience for their customers.
Cable or Multi-Service Operators (MSOs) are undergoing a multi-year upgrade of their Hybrid Fiber Coax (HFC) access infrastructure. To provide a better quality of experience to subscribers, they are delivering higher capacity to smaller groups of homes and pushing fiber closer to the edge of the network.
HFC Fiber nodes, which on average service 500 homes per node, are being replaced with 10 to 12 Digital Fiber nodes. These nodes will now service 40 to 64 homes, be pushed deeper into the access, and increase per-user capacity.
An incredible amount of digital fiber nodes are expected to be deployed in the next few years, from tens to hundreds of thousands globally in 2018 and 2019. Fiber densification, the ability to pack as much capacity as possible over the limited fiber resources available, is of critical importance to achieve business objectives.
Finally, the simplest example of fiber densification is the hyperscale data center interconnect application. Global content providers are deploying huge amounts of fiber between massive data centers to maintain their aggressive pace of innovation and keep up with the doubling of bandwidth they are seeing on a yearly basis. more>

PLM ALM Integration using Teamcenter Linked Data Framework
By Jatish Mathew – Reports from the field indicate that the power window system in a particular car model has a defect. The anti-pinch feature does not work all the time. Customer service files a high priority incident report.
Representatives from different engineering teams meet and try to find the root cause of the problem.
The problem may be due to hardware failure such as a stuck button, it can be in the embedded software, or it can be a combination of hardware-software. Each team analyzes the problem using their tools and processes but when these teams need to coordinate what do they do?
The biggest worry for engineers, when they work with different teams, is that the practices, processes, and tools they use are diverse. How do they ensure that teams effectively collaborate without losing the processes and systems that work well for them?
In this post, we will explore how hardware (PLM domain) and software (ALM domain) teams work together to solve the power window problem. The automotive company in our example uses Linked Data Framework (Customer Only Access) to integrate and collaborate across domains. It is an integration framework to integrate different enterprise information systems such as Product Lifecycle Management (PLM) systems and Application Lifecycle Management (ALM) systems.
PLM ALM integration using Linked Data Framework helps with the following business problems:
- How do you implement a process such as change management across different domains such as PLM and ALM?
- How do you avoid creating new applications, and avoid user training?
- How do you enable ALM users to access PLM data without learning PLM concepts or new tools?

Standards Update: 200GbE, 400GbE and Beyond with Pete Anslow – “Live” from Geneva
By Helen Xenos, Pete Anslow – IEEE 802.3bs defines the technical specifications to support MAC or Ethernet data rates of 200Gb/s and 400Gb/s – double and four times the capacity of Ethernet rates today – that can operate at distances to meet the requirements for most applications. The objective of the project is to define specifications that will enable multi-vendor interop, using appropriate technologies that will meet the performance and cost points required by the industry. Cost will be a function of volume and yield of components, so we aim to use existing components and technologies that can be supplied by multiple vendors.
The IEEE 802.3bs project defines physical layer specifications for operation over 100m (400GBASE-SR16), 500m (200GBASE-DR4 and 400GBASE-DR4), 2km (200GBASE-FR4 and 400GBASE-FR8), and 10km (200GBASE-LR4 and 400GBASE-LR8) distances.
The most popular formats to meet the majority of core router to transport distance requirements are the 2km and 10km devices.
While the per lane technology for 100GbE used 25Gbps NRZ signaling, we are now using PAM4 signaling for most of the new electrical and optical interface specifications. PAM4 stands for Pulse Amplitude Modulation with the “4” indicating 4 levels of modulation. 50G PAM4 requires a more sophisticated receiver design but allows for the doubling of capacity per lane while reusing existing high volume, reliable electro-optics. The signal operates at a symbol rate of 25GBaud (speed of the electro-optics), but carries 2 bits per symbol, thus doubling the capacity (50G per lane). more>
Accenture – With everything from agriculture to aeronautics in the midst of paradigm shift, a cautious approach to adopting new technologies simply can’t keep pace.
Nor will adopting just one innovation suffice. Effective adaptation almost always involves a combination of innovations working together: a dash of machine learning here, a sprinkle of automation there.
As Accenture Chief Strategy Officer Omar Abbosh describes: “You’re combining a series of innovations, one on the back of the next, to do something fundamentally different… You’ve all heard about Big Data and artificial intelligence and internet of things… They are all very meaningful in their own right, but when they come together they can have a massive impact on business and society.”
The benefits of combination abound. For example, amalgamating just five technologies—autonomous robots, AI, 3D printing, big data, and blockchain—could save industrial-equipment companies a total of $1.6 billion. more>
