The questions that will shape the future of capitalism
Advocates of free markets must engage in the public debate about them
By John Paul Rollert – What is the promise of capitalism?
That may seem like a strange question, and when I ask it of my MBAs, I suspect they regard it as an exercise in the pedagogical pastime Guess What Teacher Is Thinking. Still I ask it, for I hope it prompts my students to think about the kinds of problems capitalism is equipped to solve as well as those that are beyond its compass.
This is hardly a matter of idle speculation, especially for those who have good reason to believe that they will someday enjoy a disproportionate amount of the system’s spoils. Those fortunate individuals sometimes need to be reminded that free markets, however mighty, will not mend their marriage, relieve their cold, or stop their brother-in-law from bragging about his golf game. Indeed, there are plenty of things capitalism can’t do, and reflecting on them is a good way of distinguishing what it can do—and what it should.
Naturally, what capitalism can and should do are not one and the same. The first is a technical matter best left to economists; the second is more of an ideological affair, the province of moral and political philosophy. The distinction is an important one, but it tends to fade whenever one believes that free markets will solve most any problem: moral, social, and political as well as economic. If capitalism can do anything, so the thinking goes, then it should do everything.
Now, with the kind of intellectual prodding the question above intends, almost no one honestly believes that capitalism can, or should, do everything. Yet up until recently, it passed for conventional wisdom, in the United States and throughout most of the developed world, that capitalism could do most things, that the obvious solution to nearly any pressing problem of social organization was freer trade, fewer regulations, and far less government intervention. more>

Expanding business models of managed wave services with Adaptive Networks
It goes without saying that no other method of network transport has ever surpassed the speed and performance that is delivered over optical networks. The many innovations in optical communications form the backbone of the robust, reliable, high capacity networks that connect our world. But what is less talked about are the billions in revenues that stem from innovative business and service models delivered over optical networks as managed connectivity services (aka managed wave services). Ciena’s Niloufar Tayebi details what can happen to evolve managed wave services in the era of Adaptive Networks.
By Niloufar Tayebi – Let’s step back in time to take a snap-shot of what service interfaces have previously thrived in managed wave service offers. In a managed wave service, the service provider is able to offer a wide range of client service interfaces: Ethernet, SONET/SDH, DWDM, storage area networking (SAN) interfaces and more.
For these managed wave services, the client is handing off an interface that is required to transport payload connecting two data centers in complete transparency without protocol conversion. This is done by either using a dedicated wavelength over DWDM or through the use of OTN containers (aka ODU).
With the growth of traffic and cost-per-bit declining, client interfaces are now evolving to higher bit rates – as happened with the evolution from SONET/SDH clients to 10Gbps clients – but also expanding in client protocols that supported 10Gbps, such as ODU-2 and 10GE.
One natural path for evolving a managed wave service is to continue the path of offering higher rate, with more emphasis on 100GE and ODU-4 client interfaces. Today it is common to look at a managed wave service and see 100GE and ODU-4 /100Gbps clients supported. With the ongoing reduction of cost-per-bit and higher rate transport, offering managed wave services at higher than 100Gbps client support also makes economic and technical sense.
Ciena’s market intelligence and global consulting teams have been tracking the market size of managed wave services. Their findings show 10GEoDWDM managed wave services are mature services contributing to 60% of managed wave service offers, while 100GEoDWDM managed wave services are the fastest growing wave services at a 30% CAGR. more>

The submarine network seascape in 2020
Submarine networks carry over 99% of intercontinental data traffic making it critical infrastructure to be protected and innovated upon at a frantic rate to maintain pace with the approximately 40% bandwidth growth in all submerged corridors of our world. Ciena’s submarine networking expert, Brian Lavallée, highlights key areas for focused innovation throughout 2020.
By Brian Lavallée – There are several key technologies that are the focus of submarine network innovation and will garner a great deal of time, money, resources, and attention in 2020. These technologies will once again allow submarine cable operators to modernize their submerged assets and not only maintain pace with voracious and ongoing growth in bandwidth demand but provide critical competitive differentiation as well. I cover below these key technology innovation areas that I believe will dominate the discussion seascape throughout 2020.
With voracious and ongoing bandwidth growth experienced for many years now, coupled with expanding rollout of 5G services that significantly increase access speeds to content hosted in data centers, cable operators are constantly seeking new ways to increase available bandwidth between continental landmasses for Data Center Interconnection (DCI) purposes – satellite networks need not apply!
Although Submarine Line Terminating Equipment (SLTE) has been constantly innovative upon at a frenetic pace for the past decade, the wet plants they connect to have experienced comparatively little innovation – until now. Wet plants leveraging SDM technology offer more fiber pairs than traditional submarine cables, and although SDM cables support less capacity per fiber pair, they have a much higher overall capacity due to far more pairs (12 and higher), which is further enhanced with power-optimized repeater (misnomer for subsea optical amplifier) designs.
As an industry proof point, the first SDM-based submarine cable deployed is the transatlantic Dunant cable, which supports up to 250Tb/s of overall capacity over an aggregate of 12 fiber pairs, which is many more than the traditional 6 to 8 fiber pairs offered on recent submarine cable deployments. more>
