There is a sea change happening in the global lighting fixture market. The market is rapidly moving to light emitting diodes (LEDs). LEDs are based on semi-conductor technology just like computer processors. They are constantly increasing in brightness, energy efficiency and longevity. Previous generation of LEDs were used for “ambient lighting,” to create moods and enhance areas with different colors; however, they were not used for their light output—until now.
Higher power LEDs now deliver powerful light outputs in addition to having a longer lifespan. For example, a 20-watt LED light tube can replace a 40-watt fluorescent light with the same light intensity brightness or better. Many products will last up to 50,000 hours (almost 6 years); that’s about 50 times longer than a 60-watt incandescent bulb or five times longer than a 40-watt fluorescent tube.
Many service providers have legacy copper cableinfrastructures. Today, they are striving to provide commercial services for small and medium-sized businesses as well as enhanced broadband services to residential subscribers. With limited CapEx and pressure to reduce OpEx, providers are searching for a logical upgrade path that is not possible with just copper cables and is not expensive with a fiber overlay.
Coax and twisted pair copper cables, while adequate for today’s needs, will eventually be challenged to deliver all the bandwidth needed for future services. Let’s face it; more bandwidth-hungry devices are tapping into the networks, with no end in sight. However, fiber is expensive to deploy unless it’s needed immediately. A solution is needed that installs easily, provides an upgrade path and minimizes upfront and Day 2 costs. Industry experience designing and constructing FTTx architectures have shown a consistent inability to estimate the consumers’ insatiable desire for bandwidth and a subsequent underestimation of fiber required in the last mile.
Barbecues, camping trips, baseball games and World Cup fever—summer in the Northern Hemisphere may be coming to an end but not all is “said and done” in the world of wireless.
The wireless industry is quickly expanding LTE coverage in countries and cities across the world with 320 networks in 111 countries. The next 3GPP technology evolution to LTE-Advanced is breaking ground, with 20 LTE-Advanced commercial deployments in 15 countries and as many as 40 or more expected by year end 2014. It’s evident that the wireless industry takes no summer breaks—a potential giant leap towards the “5G” future is currently being researched and developed for deployment plans in 2020 or later.
you install fiber optic infrastructure, how can you be certain that it will
support future applications? As a fiber optic network operator or owner, what
assurances do you have that your fiber optic infrastructure is designed and
installed based on industry established best practices? As a fiber optic
technician, how do you know that what you have been doing these past few years
is correct? These questions, and many like them, are what lead to the
development of several standards and best practices found within the network
industry has an insatiable appetite for more bandwidth, faster speeds, lower
latency, longer distances and better sustainability. With this appetite comes
the need for more critical control over how these fiber optic infrastructures
are designed and deployed. The mindset of “I have always done it this way” does
not really work in this new era of higher-speed technologies. It is a new game
with new rules.
We have been working with our partners on
exciting new technological advancements in support of optimizing high-speed
transmission over multimode
fiber (MMF). These advancements include a
next generation MMF that we refer to as wide
band multimode fiber (WBMMF). To understand the benefits of WBMMF, let’s start by reviewing today’s commonly used transmission technique
for very high data rates over MMF.
As data rates have advanced above 28Gbps, a technique called multiplexing has been successfully standardized and deployed to deliver higher
rates for applications such as 40GE and
100GE, with 400GE and 128GFC currently in standardization. All of these applications
employ a type of multiplexing on MMF
that involves dividing the data into lower speed constituents and conveying
each over its own individual fiber within a multi-fiber cabling infrastructure, commonly
referred to as parallel transmission.
The evolution to a converged optical network is well underway. Service providers are transitioning to all-digital video services and even IP-based video, achieving significant capacity gains. Today, most multiple system operators (MSOs) and broadband operators, who evolved through the video service delivery business, predominantly use hybrid fiber coax (HFC) infrastructure. Operators also have Ethernet business and wireless backhaul services provided through a Metro Ethernet point-to-point (P2P) or a passive optical network (PON) solution using separate fibers from the HFC network.
Current networks still have substantial bandwidth capacity potential; however, it can be enhanced through key network changes. If operators plan to stay competitive and support future growth, they must devise a plan that evolves the network from a HFC platform to a converged optical platform delivering Ethernet/IP-based services to the user.
In today’s data centers, many key technologies such
as virtualization and cloud computing have greatly improved efficiency and
asset utilization; however, they come with a much higher level of network
It is time to implement intelligent connectivity
systems − based on the AIM standards − in the data center to help manage this
complexity and ensure that the physical layer is fully-documented and can
automatically report all changes.
CommScope takes another step (maybe it is closer to a leap) forward with the availability of its 10G Ethernet Passive Optical Network (EPON) solution set enabling network operators, whether they are operating public or private networks, to deliver bandwidth to users well above legacy EPON or GPON (Gigabit Passive Optical Network) rates.
You might be asking yourself, “So what? Why would anyone need a 10G PON solution?” It is true that people hardly ever need anything that comes close to 1G, much less 10G. So, why do they need 10G?
First, while most consumers may not “need” 10G for standard Internet usage, commercial services and business users may require it. There are users that legitimately need services faster than 1G. A 10G EPON solution enables service to those with the benefits of PON technology.
If you think energy reduction, conservation or “green” energy is a fad, think again. Reducing everyone’s carbon footprint is at the forefront of every industry conversation, even in the cable industry.
Back in June, the Society of Cable Telecommunications Engineers (SCTE) announced a multi-year campaign to provide cable operators with new standards, technology innovation and training aimed at reducing power consumption 20 percent on a unit basis. In addition to reducing power consumption, the Energy 2020 campaign aims to:
- Reduce energy cost by 25 percent on a unit basis
- Reduce grid dependency by 10 percent
- Optimize the footprints of technical facilities and datacenters by 20 percent
- Establish vendor partnerships that will impact hardware development
CommScope understands how important it is for cable operators to deploy the right solutions to reduce their energy consumption from both a CapEx and OpEx standpoint. We are a supporter of the SCTE’s Smart Energy Management Initiative (SEMI) program and additional educational programs.
In July, it was revealed that the UK government would invest millions of pounds on mobile broadband on trains for passengers, with a new service that could be made available within the next three to four years and improving connectivity by 10 times. The upgrade will stop passenger’s connectivity being “constantly disrupted by poor signal,” as has been reported. The investment will mean trains will be upgraded to better pick up mobile signals that are then distributed via Wi-Fi within the trains.
In some countries, such as Sweden, in-train connectivity has already been upgraded enabling commuting experiences with seamless coverage. One country that has taken the lead in developing wireless access on its rail networks is Switzerland. InTrainCom, the consortium made by the Swiss mobile operators, has been focused on driving significant investment in broadband train connectivity in partnership with the national rail provider. Switzerland was one of the first countries to deploy wireless services on board trains, which has, in turn, driven the appetite and usage figures of wireless connections.
