blog post is part of a new series called CommScope Definitions, in which common
communications network and data center industry terms are explained.
The time span between
the emergence of new generations of technology is growing shorter and this
phenomenon is especially apparent within the data center. Most data centers
started as connectivity technology housed in wiring closets, then quickly
started requiring entire floors. Today, many data centers are in their own
buildings comprised of hundreds of thousands of square feet housing hundreds of
millions of dollars in IT and facilities investments.
Hidden in the woods, miles away from city lights and busy highways, there is a 100-year old cottage to which I return every year. As night falls and the wind dies, the absence of noise – both acoustic and optical – becomes very noticeable. Or rather, I notice what I can then hear and see, like a faint creak in the timbers, an owl hooting in the distance and a million stars against the blackness of space. I highly value this experience which no money can buy in the urban environment I otherwise inhabit.
The above illustrates the importance of Signal-to-Noise Ratio (SNR). How well we perceive is not determined just by absolute loudness or brightness but more importantly by the contrast of an object or signal against its surrounding environment. In a radio receiver when noise levels rise, weaker signals cannot be reliably received and eventually become undetectable. Merely amplifying does not help at this point because the levels of signal and noise are equally raised and SNR does not improve.
The Internet has certainly changed the way we shop and conduct research. In the past, when you wanted to buy a car, you had to go to several dealerships to test drive a few cars and collect all the product information. Nowadays, shoppers do most of their research online.
They research the types of cars, compare prices, review safety records and other benefits, all before they go to the dealership. Customers have educated themselves about the car before they even speak to a salesperson.
CommScope continues to update its website about the solutions we manufacture for the enterprise and wireless industries. We want to provide you with the most accurate information on those solutions.
What’s the big deal in passive intermodulation (PIM)? PIM robs a network of the speed, efficiency and coverage needed to keep up with today’s wireless device users. Think about this—a one decibel (dB) degradation in uplink sensitivity equates to around 11 percent reduction in coverage! A poorly performing connector, for instance, can easily contribute much more than 1dB of PIM interference, and cause a hefty hit on network coverage.
Enter CommScope’s new 4.3-10 small connector series. The 4.3-10 connector interface certainly is smaller than the globally dominant 7-16 connectors used across the wireless space, but we’ve done small before. Type N connectors are small. The 4.1-9.5 connectors are small. So why do we need another interface?
Due to their rock-solid PIM performance and, yes, their small profile, 4.3-10 series interfaces are being adopted by a number of the biggest operators, and are being seriously considered by many more.
The future is finally upon us. For the past several years
industry pundits have predicted
that bandwidth needs
in the building will
exceed 1 Gigabit
(G), and that infrastructure decision makers would need to be
ready to support this requirement
. To properly prepare
for this reality,
CommScope has long recommended
for new installations
. Since Category 6A enables 10G speeds up
to 100 meters
, it is a prudent way to prepare for future bandwidth needs
The relentless growth in demand for wireless data services means that mobile networks are getting ever denser. Network operators are deploying cell sites of all sizes and putting more equipment on existing sites to meet the demand. The cost of acquiring and building a new site is considered only when all other options have been exhausted. Companies operating and leasing cell tower infrastructure want all assets operating to their full potential.
These market forces put a major responsibility on the structural engineers tasked with assessing existing towers for additional equipment. Too conservative a judgement results in lost revenue or unnecessary money spent on strengthening the tower. It is therefore essential that engineers have accurate weight and wind loading information for the tower equipment provided by manufacturers.
Whenever there is talk about data center efficiency, energy
is usually the first thing that comes to mind, especially server power and
cooling efficiency. However, there is so
much more to an efficient data center.
Efficiency should be thought through and achieved across the
entire physical infrastructure of the data center. Some key components of the data
center’s physical infrastructure are:
In my previous blog post, Calculate Your Fiber’s Performance, I explained how calculators and tools are a cornerstone of the support that CommScope provides to the industry; however, tools are not the only useful assets. We also make available a lot of technical documents for designers to better evaluate our products for solving their customers’ problems.
In the Enterprise arena, we have always provided cabling performance specification documents. These are greatly appreciated by customers because these assets outline what can be done (and not done) with each CommScope solution.
We all know technology changes at the speed of light. New applications are invented every year. Our research and development engineers are constantly updating our technical document library. We run the proper tests to assure our customers that our solutions will support their needs.
When people talk about connectivity,
they usually refer to bandwidth and
the trend of network traffic. Bandwidth is certainly an important aspect of
connectivity; however, bandwidth is not
the whole story. It’s crucial to understand that efficiency is another important
aspect of connectivity.
I have the honor of speaking at this year’s Ethernet Technology Summit in San
Jose, Calif. The event is April 14-16
and my presentation will take place April
15 at 8 a.m. My topic, “Build a
Solid Cabling Foundation for High-Speed Ethernet,” will cover what I believe
are the most important aspects to achieving
better efficiency in connectivity.
