In part one of
this series, I
discussed the tradeoffs between hybrid fiber coax (HFC)/DOCSIS and FTTH, and
the fact that MSOs are increasingly deploying FTTH to portions of their service
this blog, I will discuss deployment challenges in FTTH networks.
FTTH networks broadly can
be divided into two types with some distinct considerations for each:
- Networks that support single-family units/homes
- Networks that support multiple dwelling units
Fiber-to-the-MDU is of significant interest. US
Census data says 17.3 percent of the US population lives in
buildings with five or more units, and depending on the service provider’s
footprint, that number could be much higher. It also presents some unique
operators—large public networks or small private networks—must keep up with the
growing demand for bandwidth
from their users. One solution they turn to is a Passive Optical Network (PON).
PON infrastructure is
an all-optical point-to-multipoint technology that provides an optical path for
a central office, headend or data center to a user terminal through the use of
optical fiber and splitters. The passive elements form the base architecture
- Gigabit PON (GPON)
- Next Generation PON
- 10G Ethernet PON (EPON)
- Radio Frequency over Glass (RFoG) networks / RF
My mom has been
right about so many things.
- I do regret that tattoo.
- That boyfriend in high school was indeed no good
- My daughter shouldn’t have eaten that whole jar
of prunes in one sitting.
Never was that more on display than when I took
that same daughter, our firstborn, to the bus stop for kindergarten. She wasn’t
scared. She wasn’t shy. And no, she didn’t miss me. I cried more. Mom was right again. She was a
kindergarten teacher for many years, so I’m not quite sure why I questioned
her. She knows how little people are when they arrive at school. Apprehensive, sure.
But scared? Nah. They’re so happy to be there.
Let’s talk about big decisions...like
marriage. As Tim Urban, one of the folks behind the popular “Wait But Why”
blog, reminds us:
“When you choose a life partner, you’re choosing a lot of things,
including your parenting partner and someone who will deeply influence your
children, your eating companion for about 20,000 meals, your travel companion
for about 100 vacations, your primary leisure time and retirement friend, your
career therapist, and someone whose day you’ll hear about 18,000 times.”
I mention this because, next to selecting your
spouse, choosing the migration path for
your data center is a piece of cake. Feeling better already, right? Let’s
break it down.
This is the fifth post in a new blog series about intelligent buildings, based on content from the CommScope Connected and Efficient Buildings e-book.
As the networking industry moves to more complex, highly available architectures, equipment manufacturers have created new software tools for network designs. The new software takes the complexity out of the network, enabling users to create a simpler way to digest the details about network operations. This trend has taken root in the servers and storage, switching and application layers of the network. The only area where this trend has not been fully embraced is within the physical connectivity of the network; however, that change is coming.
A data center’s layout is just as important as the type of
fiber cable or intelligent software inside it. The whole infrastructure and
server connectivity hinges on the design. Three factors should be considered
when putting everything together:
- The size of the data center
- Anticipated growth
- Whether it’s new installation or an upgrade to a
There are three main designs to choose from, yet there’s no
one-size-fits-all. Each design has its pros and cons.
challenging to keep up with the latest standards development for data center
of mine participate in the industry standards for Ethernet and cabling, and
they tell me that the standards meeting agendas are so busy that they nearly
have to run from one meeting to the next to keep up with all of the activities.
There was a time when Ethernet standards were very
predictable; you could nearly set your calendar to every five years or so, when
a new application speed would come out that was 10 times
faster than the previous one. Today, there are no less than six new application
speeds in development, which is amazing considering only six application speeds
have been developed to date in the 30+ years that the IEEE 802.3 standards have been published.
As the wireless industry looks toward 5G, it can be easy to forget that 4G/LTE will be the workhorse of wireless networks for many years to come. Before we reach 5G, mobile operators will continue to be challenged by increases in mobile data traffic. Operators face constant pressure to improve network capacity, enhance network speeds and lower deployment and operating costs.
Designing data centers can be
challenging when there is uncertainty in the forecast. This often leads to the
power, cooling and connectivity equipment being either under- or over-engineered.
At CommScope, we embrace the many years of experience we have in addressing customers’
pain points and assessing rapidly changing technologies and shifts in the business
to look ahead toward future trends. The
five key trends in the data center that we see having a direct and sustained
impact on infrastructure design and operations today and in the future are:
- Bandwidth explosion
- Shift to the

- New disruptive
