Life’s tough in the great outdoors, especially for packet-optical network gear
By Frank O. Miller – Packet-optical network gear gets pretty pampered in the data center, with regulated temperatures and a whole team of techs on hand to fix any problems. But what happens if you want to put your equipment outside, closer to your customers? How do you know your switches and other gear will be tough enough to survive?

The answer’s simple: regular data center infrastructure won’t be up to surviving in the great outdoors. Instead, you’ll need equipment that’s street-tough, temperature-hardened, and always available – come snow, rain or shine.

So let’s take a moment and think about some of the biggest challenges that could impact your network equipment in the great outdoors…

In mainland Europe, the temperature differentials between summer and winter can be extreme, requiring all network equipment in street cabinets to be temperature hardened. In Germany, for example, many areas experience daily averages of 0°C in the winter, with summer daily averages of around 24°C. In Russia, the swing is even greater, with winter temperatures of -25°C in many regions and summer averages of 30+°C. more>

4 ways an Adaptive Network can overcome today’s challenges and take your network to the next level
By Françoise Pouliquen – There is a relentless push-pull from rapid business and technology change affecting operators today. On one hand, dramatic growth in subscriber demands are driving fronthaul and backhaul traffic and putting networks under intense pressure. While on the other, there’s an industry wide race to develop and commercialize new revenue-generating services, such as IoT use cases and 5G mobile services – and to implement the network technologies and architectures needed to support and deliver them. On top of that, new market entrants, including some of the largest internet companies, are deploying massive-scale network connections that support low-cost data transport between key locations and data centers with unrivalled economies of scale.

The challenges for operators are; how to take exponential traffic growth in stride; how to prepare the network for the next-generation of IoT and 5G use cases; and how to remain competitive on price with large connectivity providers in the market.

Here are four key ways an Adaptive Network can help:

  • Increasing network agility and efficiency
  • Future-proofing the network with industry leading packet-optical solutions
  • Helping avoid vendor lock-in with open networking
  • Driving network innovation in strategic partnership

The Future of the Internet Is Fiber Deep
By Elias Cagiannos – Netflix is the poster child for over-the-top (OTT) content and has no doubt played a large role in shifting the status quo when it comes to our entertainment and viewing habits. The company can be credited with reimagining content distribution — investing in homegrown content and a content delivery network to feed our binge-viewing habits.

However, these habits are primarily supported on MSO networks, which have one of the best internet service products on the market. These companies are focused on the future, making investments in the people, processes and infrastructure necessary to help them match their capabilities to a new generation of users.

Consumer demand for improved viewing options has created an environment where MSOs can’t tolerate service disruptions or quality issues. However, aging coaxial plants, analog repeaters and limited spectrum make meeting customer demand for fast and reliable service a challenge. MSOs recognize this and are already moving in the right direction, but they will advance even faster with fiber deep — the concept by which operators push fiber closer to the end user, which helps improve service. more>

FlexE: 3 reasons network providers are interested
By Helen Xenos – FlexEthernet, or FlexE, is a client interface standard being defined by the OIF that allows for a variety of Ethernet MAC rates (10GbE, 40GbE, nx25GbE) that are decoupled from Ethernet PHY (physical interface) rates.

Wait, what?

You may have heard about FlexE and even read about operators trialing FlexE in their networks, but unless you are intimately involved with standards activities or Ethernet protocol implementation, translating FlexE to its resulting networking value may not be obvious. For most of us, it is only once you start to look at the drivers behind the development and dig into which of today’s challenges it solves, that you can determine whether FlexE is something that makes sense for your network. more>

The Adaptive Network: Why automation alone isn’t enough
By Keri Gilder – Just imagine, instead of 70, your heart rate was at 100 beats per minute. This could be a warning sign that you are on the verge of having a heart attack.

If your doctor were to get this information in real time, they could check the readings against your medical records and see that this is completely out of the norm and then warn you to seek medical assistance immediately.

However, if your personal trainer received that same information, would they reach the same conclusion as your doctor? Your trainer has access to a different database, which might show your resting heart rate as well as the rate during high-intensity training. Knowing that you are likely exercising, they would instead conclude that there is no need to go to the hospital after all.

This clearly demonstrates that just accepting raw data without filtering and proper analysis is no longer good enough and can potentially have serious repercussions. Instead, it is critical that we have diversity of thought when it comes to how we interpret data.

This is not just true for our health or other day-to-day scenarios, but can also be applied to the communication networks that carry and house our information. more>

Why the Secret Behind Strong Early Adoption of 400G Technology is … 200G

By Helen Xenos – This month, we shipped our 5,000th 400G-capable coherent optical transponder, confirming our prediction that the use of 400G technology is ramping 3 times faster than 100G.  What may come as a surprise, however, is that the dominant application driving 400G deployments is not 400G, but 200G (long haul-datacenter interconnect to be precise).

Why? The technology that enables 400G wavelengths has a lot to do with expanding the application space for 200G as well.

To fully understand the demand drivers for 400G, it’s important to clarify the various ways 400G is defined. The term “400G” is quite popular in today’s optical networking conversations, but can also have different meanings depending on the context in which it is being used.

So, which applications are driving 400G deployments? We hear so much about the fast-growing metro WDM market, 400ZR and the need to maximize capacity for short reach DCI applications, that intuitively you would think this is the “sweet spot” application.

In fact, the most popular use case we see for early 400G adoption is to support the rise of 200G long-haul for aggressive DCI network builds. more>

4 Data Center Interconnect Developments You Need to Know
By Kent Jordan – The Data Center Interconnect (DCI) market is evolving rapidly and new compact, modular devices have been introduced to help network operators quickly and easily deploy new capacity to keep up with demand. But, as the adage says, “the more things change, the more they stay the same”. So, what’s new with DCI and what hasn’t changed in the last year?

One thing that hasn’t changed is the need for more interconnect capacity. Interconnect bandwidth growth is still on the rise, and it’s growing rapidly. By 2020, interconnect bandwidth has been forecasted to grow up to 5,000 Tbps, with double-digit growth rates across a variety of industry segments from Cloud and IT to Healthcare and Energy. All are poised to experience large capacity growth in the coming years, which means many of the same challenges from the past year still exist.

Network operators are challenged with keeping up with growing demand and offering content and/or services globally. They also have a need for automation to speed bandwidth activation and improve their customers’ quality of experience. On-going operational costs remain a challenge as well, with a need to reduce footprint and power consumption. more>

5 key wireline network improvements needed for 5G
By Brian Lavallee – Ask an end-user about how their phone connects to the network, and they’ll likely only talk about cellular or wireless technology, which is also where most of the current 5G industry hype is focused, and for good reason, as this is the first part of the network to be upgraded. However, the reality is that RAN (Radio Access Network) only makes up a small portion of the end-to-end path that data from a connected device must travel to provide connectivity. The rest of the path is primarily a fiber-optic transport network.

With 5G coming soon, featuring data rates as much as 100 times faster than what’s currently available, the wireline infrastructure that connects end-users (man and machine) to accessed content residing in data centers, must be ready to support upwards of 1,000 times more data flowing across it.

How can network operators prepare? Well, here are five key areas within the wireline network that will need to be upgraded and modernized to support 5G.

  1. Fronthaul
  2. Scalability
  3. Densification
  4. Virtualization
  5. Network Slicing

The move to 5G won’t be a simple network upgrade. It’s a long journey with a high-performance wireline network as the critical component to commercial success for both 4G strategies and the evolution toward 5G. more>

From Land to Sea to Cloud
By Brian Lavallée – Submarine networks carry over 99% of all telecommunications traffic between continental landmasses making them easily classified as critical infrastructure. There’s also no “Plan B” for these submerged assets, so they’ll continue to act as the jugular veins of intercontinental connectivity for years to come and will thus require constant technology innovation to reliably and securely maintain this pivotal role.

But exactly what traffic is transported back and forth on seabeds around the world? According to respected industry analyst firm TeleGeography, it’s increasingly Data Center Interconnection (DCI) traffic, and LOTS of it.

It’s projected that Internet Content Providers (ICPs) will soon account for the majority of submarine traffic in all regions of the world. Impressive for a group of companies that just over a decade ago, were essentially non-players in the submarine networking market.

Given the astonishing amount of DCI traffic added to traditional wholesale traffic, several new technologies were introduced to address this extraordinary growth, which sits at around 40% CAGR worldwide, according to TeleGeography. more>
