How coherent optics improve capacity, performance and competitiveness for cable MSOs
Cable Multiple System Operators (MSOs) will be using coherent optics in their access networks to help solve a vital business challenge: the need to improve scale and reduce costs while delivering high data rates to end customers.
By Fernando Villarruel – MSOs must build a foundation for their networks that provides the needed capacity, introduces significant operational and cost efficiencies, and positions their businesses for future growth. This growth includes symmetric bandwidth support for the evolution of packet cores to cloud and aggregation of multiple revenue streams including mobile, business services and IoT.
Coherent optics facilitates growth because it enables massive scalability and maximizes network performance while using far fewer components, reducing equipment costs as well as the time and effort it takes to manage the network. These cost and operational benefits allow MSOs to be more competitive as they can place greater attention on delivering a compelling and differentiating customer experience.
Coherent optics employ a technique well known in the cable RF community—QAM, but in optics! This technology uses sophisticated symbol-based modulation scheme with higher baud to efficiently use the optical spectrum available so MSOs can optimize capacity and reach for a given link. With Ciena’s recently announced WaveLogic 5, we will be able to support 800Gb/s in one wavelength, for transport, and up to 200Gb/s in one coherent pluggable wavelength, in access! more>

Digitalize battery manufacturing for a greener future with electric vehicles
By Vincent Guo – The electrification of automobiles is gaining momentum globally as many countries have laid out plans to prohibit the sales of internal combustion engine (ICE) cars. The closing deadline is 2025 for the Netherlands and Norway, with Germany and India to be the next down the line in 2030, followed by UK and France in 2040. Other major economies in the world provide aggressive initiatives to push the electric vehicle (EV) to the market. For example, USA, China, Norway, Denmark, and South Korea have been implementing cash subsidiaries to EV buyers over $10,000 per vehicle, with Denmark and South Korea paying the consumer almost 20,000 Euro for each car purchased.
These incentive plans, however, also indicate that the price of EV is still high comparing to traditional cars. Independent research shows that the cost of the electrical powertrain is roughly 50% of the EV while, while the cost of the powertrain for ICE cars is only 16%. While it is largely true that the components of a car, whether it is an EV or ICE car, are largely similar except for the powertrain, the source of the difference in total cost is obviously the powertrain. The most expensive component is the battery pack, which accounts for roughly half of the powertrain and a quarter of the entire car.
Fortunately, the cost of the battery is going down steadily in the past 10 years. It is about to hit the point that the total cost of an EV is competitive to an ICE car and the point is about 125-150 USD/kWh.
As a result, battery manufacturing capacity has been ramping up quickly. Tesla is leading the way by its Gigafacotry in Nevada with target annual capacity of 35 GWh. Yet the race is tight as the battery manufacturing in Asia is catching up. CATL of China had recently announced a plan to boost its capacity in Germany to 100 GWh. more>

BAR Technologies uses Siemens Digital Industries Software solutions to create a new class of sport yacht
Siemens – With an optimized hull and dynamically adjusting foils that enable greater efficiency over a wider range of speeds, it’s a boat designed for both performance and comfort. The Princess Yachts R35 was made possible by BAR Technologies, which uses highly specialized techniques and processes when designing an America’s Cup racing yacht. BAR Technologies is now offering its unique expertise to customers across the marine industry.
Princess Yachts first approached BAR Technologies with the aim of creating a completely new design that would attract people who had not previously considered buying a boat. The new design was to be an entry-level purchase: a day boat that was exciting yet easy to drive. Paul Mackenzie, director of product development at Princess Yachts, explains: “We have a very high percentage of return customers and once they are in the Princess family they tend to move up our range, so introductory boats have always been important. However, most people who buy a Princess are already boat enthusiasts. We were looking to expand our potential market, closing the gap between boat owner and car owner, with a product that could be positioned alongside a super car.”
Simon Schofield, chief technology officer at BAR Technologies, adds “Our brief was to devise a technically driven design with increased efficiency and accessible performance, yet retain the luxury and quality that Princess is known for. The digital modeling and simulation tools and techniques that we have established over several years were critical to the fulfillment of the brief.”
The integrated virtual environment at BAR Technologies uses solutions from Siemens Digital Industries Software. These include NX™ software for product design,Teamcenter® software for data management and the Simcenter™ software portfolio, which includes Simcenter™ Nastran® for engineering analysis and Simcenter STAR-CCM+® software for computational fluid dynamics (CFD) analysis. more>
