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>

Avoid outage outrage: Why AI-assisted operations is the next big thing for networks
By Kailem Anderson – You can’t go far in the broader tech industry these days without coming across a conversation about the future of artificial intelligence (AI). I’ve been talking about AI and machine learning (ML) in telecom networks for quite a while, and for good reason: network operators desperately want and need AI to help simplify their complex network operations.

Troubleshooting and resolving issues in today’s increasingly complex and dynamic networks has become a major operational burden, complicated by multiple management systems and a flood of raw network data and alarms.

This results in two major challenges. First, the flood of raw data obfuscates true insight into the state of the network, making it difficult to detect indications of potential network outages before customers have been impacted. Second, the “trouble-to-resolve” process becomes slow and tedious as the team struggles to identify, isolate, and rectify the issue’s root cause.

These challenges can result in network troubles that last for weeks or even months. In North America alone, an IHS Markit report from 2016 estimated that network outages cost enterprises $700 billion a year in lost revenues and productivity.

To address these challenges, Blue Planet has today introduced a comprehensive solution built around AI and advanced analytics. more>

The Next Wave Of Digital Growth in India
By Gautam Billa – Demand for wireless mobile broadband in India has been one of the most prevalent technology trends in recent years, putting more pressure on operators to prepare their networks for digital growth in India. Fueled by a considerable drop in smartphone prices and broadband tariffs, the consumption of mobile data dramatically escalated last year.

In fact, wireless broadband subscribers more than doubled in two years, from 200 million in 2016 to 493 million in 2018, according to data released by the Telecom Regulatory Authority of India (TRAI).

The expansion of 4G networks beyond major cities and into rural areas in India has led to better coverage and quality of services, resulting in more subscribers and data consumption. Content in local languages has greatly improved, further contributing to the rising demand for data services across India.

The growth is happening at a tremendous rate and isn’t showing any signs of stopping. According to the Ericsson Mobility Report, the monthly data consumption per smartphone in India will reach 15GB by 2024, growing at a CAGR of 14 percent from 6.8GB in 2018. India will have more than one billion smartphones by 2024 and 80 percent of the users will have 4G LTE connections, according to the report.

Video, Internet of Things (IoT), and cloud-based services will further drive demand for broadband in both consumer and business segments. Low-latency gaming, applications, and business services are also increasing in popularity. more>

Top 5 business benefits of modernizing legacy networks
By Wayne Hickey – Modernizing legacy networks is a hot topic, and for very good reasons.

Consider this – your legacy network is rapidly headed to obsolescence, while your packet-based applications are growing. Legacy applications are hindering your revenue growth opportunities, consuming your budget, and degrading your customers’ quality of experience, which can lead to the loss of your existing and/or new customers.

Two primary factors are driving the migration of legacy networks; (1) the imminent phase-out of legacy systems, and (2) the need to use modern packet networking techniques to improve network efficiencies, serve end-users better, and open up new revenue-generating business opportunities.

Let’s further break it down into the top 5 business benefits of modernizing legacy networks:

The biggest bang for your buck is to reduce the number of networks you operate with the goal of getting to a single, common network. Why? Running parallel networks is costly, complex, and ultimately unrealistic. Network silos are costly to manage and prevent the use of common features, toolsets, and services. more>

Delivering high-bandwidth, revenue-generating services in minutes, not months
By Frank O. Miller – Many operators’ networks have grown organically to keep pace with rapidly growing traffic demands, with new technology added incrementally over time. This has resulted in multi-vendor, multi-domain networks that are difficult to manage and support. There are also major challenges when it comes to understanding where available capacity exists in the network, requiring consultation between multiple teams before new services can be provisioned and turned up. Additional effort and lead time are needed when service offerings are being newly designed and rolled out to the market.

These challenges typically result in very high costs for operators, who spend large amounts of time performing manual ordering, feasibility appraisals for new services involving multiple teams, manual configuration steps, and manual resource provisioning across several network layers and domains. As an additional challenge, new multi-vendor, physical or virtual network elements that support new service offerings may need to be introduced and integrated into Operational Support Systems (OSS) on a piecemeal basis, resulting in costly integration projects that result in a more complex operational environment.

Without a simple way to assess available capacity across the network, planning for new services is a time-consuming and difficult process. Most operators remain highly dependent on their vendor relationships in this regard, putting in frequent requests to understand if new services can be supported on existing infrastructure. Sometimes there is available capacity on the network, while other times a network buildout needs to be initiated with a vendor change request – which can be very time consuming and expensive.

All of this makes current, manual approaches to capacity planning and service provisioning unsustainable, particularly as customers’ expectations for on-demand, high-speed connectivity services continue to increase. more>

500G transpacific. Yep, we did that!
The news from SubOptic? Let’s start with our successful single-wavelength 500G field trial over a 9,000km transpacific cable. Ciena’s Brian Lavallee explains more about this milestone as well as other highlights from this important technical conference.
By Brian Lavallée – SubOptic 2019 has recently come to a close, and as the locals say, “laissez les bon temps rouler”, or let the good times roll – and they did.

We shared the news of a successful single-wavelength 500G field trial over a 9,000km transpacific cable, which was completed just before the event. Of course, this means we can also do 500G single-wavelength transmission across much shorter transatlantic distances too. The transpacific field trial leveraged our very latest WaveLogic 5 Extreme coherent optical technology, which truly takes our pioneering submarine networking solution,

GeoMesh Extreme, to the extreme. In just under a decade, we’ve leaped from 10G to 500G transpacific – a truly impressive feat.

How did we achieve such performance?

By leveraging advanced Digital Signal Processing (DSP) capabilities, 95Gbaud operation, Probabilistic Constellation Shaping (PCS), throughput-optimized FEC, and nonlinear mitigation techniques. more>

Tomorrow’s cities: evolving from “smart” to Adaptive
Cities are going smart – trying to deal with the proliferation of people, sensors, automobiles and a range of devices that demand network access and generate mind-boggling amounts of data. However, being smart is not an instance in time, and a “smart city” is not static. To be worthy of the name, a smart city must continually evolve and stay ahead of demand. This is only possible if the city’s underlying network is just as smart and can adapt to its constantly changing environment.
By Daniele Loffreda – Cities are constantly in flux. Populations move in; populations move out. Demographics change, economic growth falls and then soars. New leadership steps in and—if you believe all the commercials—technology will make everyone’s life better.

Municipal governments understand the need to consider which smart city applications will best serve the demands of their diverse demographic segments. The City of Austin’s Head of Digital Transformation, Marni White, summed up these challenges stating, “Our problems will continue to change over time, so our solutions also need to change over time.”

The one constant in the smart city is the network running underneath these solutions—and the truly smart city has a network that adapts.

Smart city applications must be aligned with where a city and its citizens want to go. Some municipalities that created model smart-cities early on have had to initiate extensive revamping. For example, the City of Barcelona has long been at the cutting edge of using digital devices and the Internet of Things to improve municipal operations; however, in 2017, Mayor Ada Colau gave Barcelona’s CTO, Francesca Bria, a mandate to “rethink the smart city from the ground up.”

This meant shifting from a “technology-first” approach, centered on interconnected devices, to a “citizen-first” focus that responds to the changing needs that residents themselves help define. more>
