Photonic integration and co-packaging: Design tools for footprint optimization in data center networks
As traffic within and between data centers continues to grow, operators need to constrain the resulting increase in power consumption to minimize operational costs. This is driving the need to manage footprint and power at the system design level. Photonic integration and co-packaging are related approaches to addressing area and power challenges for networking applications.

By Patricia Bower – Data center networks have evolved rapidly over the last couple of years, in large part due to the scalability and flexibility supported by today’s compact modular DCI solutions.  System designers leveraged advances in key foundational technologies to pack significant capacity and service density into these products, and their popularity is growing as these solutions capture new market segments.

The same advances have also paved the way for new consumption models for coherent optical technology in the form of footprint-optimized, pluggable solutions. As traffic growth for server interconnect within data centers continues to increase, greater for interconnect between data centers (DCI) will be required.

Scaling of data center traffic to get more bandwidth adds to the power consumption overhead and real estate requirements for operators which adds to capital and operational costs.

With each new generation of switching platform and coherent optical transport systems, designers have met the challenges by increasing throughput density and reducing power/bit. Both intra-DC and DCI traffic flows will increasingly rely on advances in foundational technologies and system design options to mitigate power consumption while maximizing interconnect densities.

What are these foundational technologies?  They include:

  • Complementary Metal-Oxide Semiconductor (CMOS)
  • Indium phosphide (InP)
  • Silicon photonics (SiPhot)

In networking applications, CMOS is the basis for both high-capacity switch chips used in router platforms and coherent optical digital-signal-processors (DSP).

InP and SiPhot are used to build electo-optical circuits for signal transport over optical fibers.  Together, the DSP and electro-optical components are the heart of coherent optical transport systems. more>

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>

SD-WAN Gets (More) Real for Service Providers

By Kevin Wade – Interest in Software-Defined Wide Area Networking (SD-WAN), which is designed to offer enterprises cohesive end-to-end visibility and control of their multi-site WAN, continues to grow. Although SD-WAN was originally envisioned to give enterprises a ‘DIY’ approach to WAN management, most industry analysts and experts agree that managed SD-WAN services are the predominant consumption model for enterprises today, and into the foreseeable future.

The trend toward managed SD-WAN services is good news for service providers, many of which were initially cautious that SD-WAN might reduce their revenues and/or weaken their relationships with key business customers. To the contrary, SD-WAN services have emerged as a rapidly growing new source of revenues, as well as one that offers service providers new opportunities to improve the customer experience.

I’ve been following the SD-WAN movement closely since nearly the beginning, and have been pleased to see some recent developments that signal the increasing maturity of SD-WAN services.

Without a doubt, SD-WAN services are becoming more established and accepted. And while Blue Planet isn’t inherently an SD-WAN solution, the deployment of SD-WAN services is one of Blue Planet’s biggest drivers and most common use cases. more>

Iceland’s data centers are booming—here’s why that’s a problem
By Tryggvi Adalbjornsson – The southwestern tip of Iceland is a barren volcanic peninsula called Reykjanesskagi. It’s home to the twin towns of Keflavik and Njardvik, around 19,000 people, and the country’s main airport.

On the edge of the settlement is a complex of metal-clad buildings belonging to the IT company Advania, each structure roughly the size of an Olympic-size swimming pool. Less than three years ago there were three of them. By April 2018, there were eight. Today there are 10, and the foundations have been laid for an 11th.

This is part of a boom fostered partly by something that Icelanders don’t usually rave about: the weather.

Life on the North Atlantic island tends to be chilly, foggy, and windy, though hard frosts are not common. The annual average temperature in the capital, Reykjavík, is around 41 °F (5 °C), and even when the summer warmth kicks in, the mercury rarely rises above 68. Iceland has realized that even though this climate may not be great for sunning yourself on the beach, it is very favorable to one particular industry: data.

Each one of those Advania buildings in Reykjanesskagi is a large data center, home to thousands of computers. They are constantly crunching away, processing instructions, transmitting data, and mining Bitcoin. Data centers like these generate large amounts of heat and need round-the-clock cooling, which would usually require considerable energy. In Iceland, however, data centers don’t need to constantly run high-powered cooling systems for heat moderation: instead, they can just let in the brisk subarctic air.

Natural cooling like this lowers ongoing costs. more>

Latest trends in optical networks- straight from NGON & DCI World
By Helen Xenos – “If you are not sitting at the edge of your seat, you are taking up too much space.”

I heard this quote from a friend recently and thought it was interestingly appropriate in describing the optical networking industry these days. No one has time to sit back. Technology is evolving at an incredibly fast pace, new developments are occurring at a regular cadence, and network providers are regularly evaluating different architecture approaches for evolving their networks.

In attending the 21st Annual NGON & DCI World event in beautiful Nice last week, I had an opportunity to get a pulse on the latest topics and trends that are driving change in the optical networking landscape.

A popular topic at all optical events – and NGON was no exception – is the discussion of the next technology breakthrough that will bring new levels of capacity scale and cost reduction to transport networks.

If we look at coherent optical shipments, capacity and average selling price data over the past decade, what is the principal way that network providers have been able to keep up with exponentially increasing bandwidth demands while maintaining transport costs relatively flat? Through coherent technology innovations that have enabled higher throughput at less cost.

So, how will we get to the next level of cost reduction?

The consistent response to this question in multiple sessions at NGON was higher baud, which means coherent optical solutions that have a higher symbol rate and can process more data per second, resulting in more fiber capacity with less equipment. more>

Reimagining Ethernet Service Delivery with Intelligent Automation
By Thomas DiMicelli – Communications service providers introduced Ethernet-based services almost 20 years ago as a more flexible and cost-effective alternative to TDM-based services. These services have been continuously enhanced over the years and are widely deployed today; however, traditional Ethernet service activation processes are increasingly out of alignment with market requirements.

I asked Andreas Uys, CTO at Dark Fibre Africa (DFA), an innovative open-access fibre optic company that operates in South Africa, to outline some of the issues concerning Ethernet service activation, and how CSPs can overcome them.

“The limitations of traditional Ethernet service activation processes are quite significant,” Andreas said. “Some of this is due to the way SPs are organized, and some is due to the reliance on manual operations; taken together, these issues dramatically slow the order to service process and delay time to revenue.”

Andreas continued: “Ethernet service activation naturally involves different departments… customer service reps generate work-orders, engineering designs the services, and the operations team provisions and manages the services. Each department has its own ‘siloed’ systems and rely on emails and spreadsheets to track workflow progress. This results in a time-consuming process, even to generate a simple quote.”

“Engineers design the service using stale data from multiple offline inventory systems,” Andreas added, “which results in non-optimal designs that waste network resources. Similarly, the operations team uses multiple tools to manually configure each element or domain in the service path, which adds cost and the potential for errors into the process.”

With fragmented systems and workflows, offline service design tools and error-prone manual provisioning, it is clear that the Ethernet service activation process needs to be updated. So what is the way forward? more>

GeoMesh Extreme: Release the Kraken!
importance to global communications, and how Ciena’s new GeoMesh Extreme allows submarine cable operators to integrate several technology advancements to enable an open submarine network solution with greater choice and performance.
By Brian Lavallée – Now that I’ve got your attention, what exactly is a kraken?

It’s a legendary sea monster that terrorized ships that sailed the North Atlantic Ocean. It was an unknown danger that dwelled the ocean deep and could attack without warning resulting in untold mayhem.

Whether the kraken legend originates from a giant squid or octopus sighting is debatable, but it terrorized sailors nonetheless, as they never knew if or when the kraken could be encountered. Legends die hard, but there are real dangers that lurk beneath the oceans of the world, and this is precisely where submarine cables live and work.

Hundreds of years ago, when the kraken was terrifying sailors crisscrossing the world’s oceans, ships were the only method of sharing information between continents that were separated by thousands of kilometers of water. This was until the first reliable transoceanic submarine cable was established over 150 years ago, way back in 1866.

This pioneering telegraph cable transmitted at rates that we’d scoff at today, but it was undoubtedly a monumental performance leap when compared to sending handwritten letters back and forth between continents, which could take weeks and even months. Imagine you waited months to receive an important letter, but couldn’t read the sender’s handwriting?! Oh, the horror!

Most modern submarine cables are based on coherent optical transmission technology, which enables colossal capacity improvements over the early telegraph cables of yesteryear, and can reliably carry multiple terabits of data each second.

We’ve come a long way in improving on how much data we can cram into these optical fibers that are the size of a human hair, housed in cables the size of a common garden hose, and laid upon the world’s seabeds for thousands of kilometers. We’ve also come a long way in being utterly and completely dependent upon this critical infrastructure, now carrying $10 trillion – yes, TRILLION – worth of transactions every day, over 95% of all inter-continental traffic, and are experiencing over 40% CAGR growth worldwide.

This network infrastructure will become more critical, if that’s even possible! more>

How AI can improve agriculture for better food security
ITU News – Roughly half of the 821 million people considered hungry by the United Nations are those who dedicate their lives to producing food for others: farmers.

This is largely attributed to the vulnerability of farmers to agricultural risks, such as extreme weather, conflict, and market shocks.

Smallholder farmers, who produce some 60-70% of the world’s food, are particularly vulnerable to risks and food insecurity.

Emerging technologies such as Artificial Intelligence (AI), however, have been particularly promising in tackling challenges such as lack of expertise, climate change, resource optimization and consumer trust.

AI assistance can, for instance, enable smallholder farmers in Africa to more effectively address scourges such as viruses and the fall armyworm that have plagued the region over the last 40 years despite extensive investment, said David Hughes, Co-Founder of PlantVillage and Assistant Professor at Penn State University at a session on AI for Agriculture at last week’s AI for Good Global Summit. more>
