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>

Variable Fonts Are the Future of Web Type
By Mandy Michael – A variable font is a single file that acts like multiple fonts. Variable fonts can improve page-load times, but their appeal goes way beyond that: Site visitors get an improved reading experience, and designers get greater creative freedom.
While it’s still early days, some software applications—including the latest Illustrator and Photoshop—and many web browsers do support the technology, and more will follow. It’s a good time to understand how variable fonts work and how to use them in your web designs.
Inventive type designers aren’t restricting themselves to expected variations, such as weight, width, or italic. They’re creating variations that address effect, readability, and style. 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.
- 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>

Getting into Travel Photography: Find the Details
By Jordana Wright – Look at a photograph with an interesting texture and it might give you the impulse to touch it.
Examine a photograph filled with pattern, and your brain may start to extrapolate that pattern or perceive movement in it. Both sensations are common and heighten the connection between photograph and viewer. We have an innate level of comfort with what we can touch and visually understand, so images with texture and pattern draw us in and make us pay attention.
When photographing Patterns, gear is probably the least important part of the equation. Patterns as a subject won’t dictate what lens to use—instead you’ll find yourself choosing a lens based on the scale of that particular Pattern. If you wanted to photograph the Pattern of sandpaper, you’d need to use a macro lens or even a microscope to draw out the dimensionality of the grain. more>
