2. FIBER OPTIC INTERNET
OR BROADBAND

3. FIBER OPTICS, OR OPTICAL FIBER
Fiber optics:
Fiber optics, or optical fiber, refers to the medium and the technology associated with
the transmission of information as light pulses along a glass or plastic strand or fiber.
Fiber optics is used long-distance and high-performance data networking.
Fiber optics are also commonly used in telecommunication services such as internet,
television and telephones

4. BROADBAND
Broadband:
• In telecommunications, broadband is
wide bandwidth data transmission which
transports multiple signals and traffic types.
The medium can be coaxial cable, optical
fiber, radio or twisted pair.
• In the context of Internet access
, broadband is used to mean any high-
speed Internet access that is always on and
faster than dial-up access over
traditional analog or ISDN PSTN services.

5. HISTORY OF FIBER OPTICS
• Though many people think of fiber-optic as a new technology, it actually dates back to the
1970s, when it was first used in telecommunications.
• In 1988, fiber-optic cables were laid beneath the ocean, connecting the U.S. to Europe.
Over the years, more and more lines were laid under the sea.
• In developed nations, fiber-optic lines replaced the older copper lines years ago, forming
the core or “backbone” of our current internet networks.
• fiber-optic networks are expanding rapidly across cities and directly to homes.

6. FIBER OPTIC INTERNET OR BROADBAND
Fiber-optic internet, commonly called fiber internet or
simply “fiber,” is a broadband connection that can reach
speeds of up to 940 Megabits per second (Mbps), with low
lag time. The technology uses fiber-optic cable, which
amazingly can send data as fast as about 70% the speed of
light.
Advantages:
• Upload and download files quickly
• Enjoy smooth online gaming and video chatting with
friends and family
• Back up your entire hard drive to the cloud, including
large photos and videos, in minutes instead of hours
• Download a 2-hour HD movie in less time, compared to
waiting 30 minutes or more over a 20 Mbps traditional
internet service

7. HOW IS FIBER DIFFERENT FROM OTHER TYPES OF
INTERNET?
Broadband:
The main difference is that fiber doesn’t utilize electric
current like other types of internet connections do. It
uses light, delivered through the fiber glass core.
broadband connection that can reach speeds of up to
940 Megabits per second (Mbps)
Dial-up internet:
Dial-up utilizes existing telephone lines, which are usually
made of copper. Dial-up uses the audible frequency of
the landline.The average speed of dial-up connections is
about 56 Kbps (that’s about 0.05 Mbps) for downloading
and uploading.

8. HOW IS FIBER DIFFERENT FROM OTHER TYPES OF
INTERNET?
DSL internet
DSL (digital subscriber line) internet also uses telephone
lines to transmit data. But in contrast to dial-up, DSL uses
inaudible frequencies. Average speeds for DSL are
between 1 and 100 Mbps for downloading and up to 20
Mbps for uploading.
Cable internet:
Cable internet uses the same line (or at least the same
type of line) that your cable TV service uses, known as
“coaxial cable”.Speeds for cable internet can vary widely,
anywhere up to 940 Mbps for downloading and up to 50
Mbps for uploading, on average.

9. IS FIBER INTERNET FASTER?
• High-speed internet connections transmit data at different speeds. In addition to
being faster, fiber is widely considered to be more reliable, and is an excellent
choice for telecommuters, gamers, multi-user households and businesses.
• CenturyLink Fiber Gigabit service can deliver symmetrical download/upload
speeds of up to 940 Megabits per second (Mbps) over a wired connection to your
router.
• In thinking about speed, you can’t ignore the impact of WiFi. The everyday
connection speed you experience can be limited by the use of wireless technology,
which tends to lose signal strength (meaning reduced bandwidth) as compared to
the wired connection that enters your router.

10. BENEFITS OF FIBER FOR INTERNET USERS
Speed : Fiber-optic Internet is many times faster than even the highest-speed copper Internet
connections, with options available that range from 5mbps to 100gbps.
Cloud Access : From customer relationship management (CRM) tools to data storage, the cloud is an
important business tool for apps, hosting, and more
Reliability : Fiber Internet connectivity offers significant reliability advantages over copper Internet
connectivity, due to the fact that fiber is much stronger than copper. Fiber-optic Internet is not
susceptible to inclement weather conditions
Signal Strength : With traditional broadband Internet using DSL or Ethernet over Copper, the signal
degrades as the user moves away from the swtich . The signal strength of fiber-optic Internet does not
degrade as quickly over distance.
Bandwidth : For businesses with a high need for data transmission, it's relatively easy to "hit the cap" on
your cable Internet bandwidth. While fiber-optic Internet for business is not truly unlimited, the
bandwidth availability is significantly higher, and speed does not decrease as high demands are put on
the network.
Security : Would-be hackers and information thieves can gain access to business cable Internet with
relative ease, due to cable tapping or other relatively simple methodologies. The only way to penetrate
fiber-optic Internet is to physically cut the fibers, which will cause the signal to disappear

11. THE IMPORTANCE OF BROADBAND
Entertainment and Connectivity:
We may browse recipes, check the latest stock
information, video chat,stream a movie, download music,
or play interactive online games. With fiber optic Internet,
ISPs are able to provide enough bandwidth to do all of
those things at once, without having to sacrifice service
quality.
Smart Homes and Security:
Smart home technology is one of the internet of
things(IOT) fastest growing markets. Connect every aspect
of your home so it runs seamlessly from your smart
device. You can also monitor and protect your home
remotely using Smart Home Security.

12. THE IMPORTANCE OF BROADBAND
Distance Learning:
Educational and enrichment opportunities for every age
group are quickly becoming the norm at colleges, adult
education programs, and even as virtual elementary schools
emerge. Symmetrical speeds, once again, are a key part of
this process. They allow students to quickly upload their
assignments from home.
Telemedicine:
Today, high-speed fiber connections allow health care
professionals to evaluate, diagnose, and treat patients in
remote locations using telecommunications
technology. Fiber optic Internet provides seamless video
connections, so patients in remote locations can access
medical experts quickly and efficiently without having to
travel.

13. THE IMPORTANCE OF BROADBAND
Ecommerce:
Ecommerce, also known as electronic commerce or internet
commerce, refers to the buying and selling of goods or
services using the internet, and the transfer of money and
data to execute these transactions.This is only possible with a
good broadband connection.
Libraries:
Particularly during economic downturns, libraries become a
haven for the public, providing computers and internet access,
books and movies for inexpensive entertainment, and
assistance with online job searching. Regardless of the
economic climate, libraries are automated to the point that
users can download digital media from home, reserve and
renew books online, and access a myriad of web-based
enrichment and educational tools.

14. GLOBAL BANDWIDTH CONCENTRATION
Bandwidth has historically been very unequally distributed worldwide, with increasing concentration in
the digital age. Historically only 10 countries have hosted 70–75 % of the global telecommunication
capacity (see pie-chart Figure on the right).
In 2014, only three countries (China, US, Japan)host 50% of the globally installed telecommunication
bandwidth potential. The U.S. lost its global leadership in terms of installed bandwidth in 2011, being
replaced by China, which hosts more than twice as much national bandwidth potential in 2014 (29%
versus 13% of the global total

15. CONCLUSION
• Broadband also has the potential to create happier, healthier, and more resilient
societies. First, as an educational tool, broadband enables people to learn new skills
to solve challenges or to develop new hobbies; it allows them to learn more about
their health to better manage conditions and symptoms from home; and it can
inform them about local issues, helping create tighter-knit communities
• As a recreational tool, broadband increases and democratizes entertainment
options, giving people more choice and freedom in how they spend their time. But
it also democratizes information, allowing people to access new ideas, information,
and resources from a variety of platforms. And as a social
networking/communication tool, broadband makes it easier to maintain and
connect with loose or physically distant social ties, helping people maintain a
broader sense of community.
