5. Huge corporation are investing
$Billions on building infrastructure
with this technology.
6. Fiber Optics the Next Big Industry Change!
Verizon Bell Telephone Comcast Cox Cable
Time Warner AT&T Google Fiber Businesses
Banks Hospitals Mobile Phone Carriers
TV Networks Government Agencies Schools
7. As a Telecommunications Technician
This will be a part of your job!
There are over 117 Million Households in the United States.
Over 18 Million Businesses in the United States
That is a lot of upgrades to fiber optics!
8. It is a fact:
• Telecommunications companies are transitioning their
networks from copper wire to fiber optic cables.
• Fiber optic cables offer many advantages over copper
wires.
• Telecommunication companies need fiber optics to
meet increasing demands for more bandwidth to
provide new services.
9. AT&T is testing its next-gen phone
network on rural areas and retirees
A new proposal by AT&T …… moves customers off the
old, copper-based phone system that has served the
country for decades and onto newer, high-capacity, fiber-
optic lines.
Google Fiber
How Fast is Google Fiber’s Broadband Internet?
Google Fiber offers bandwidth speeds up to 1,000
Megabits per second (Mbps), one Gigabit per second
(Gbps). Of course, such speeds are over 100 times faster
than most connections in the United States.
Comcast / Xfinity
Comcast's Metro Ethernet services, which provide
access to the company's next-generation fiber
optic network for businesses with high-bandwidth
needs in multiple locations, are part of an ongoing
strategy to expand Comcast's portfolio of business
services to meet the requirements of larger customers.
Verizon / FiOS
Verizon lets its copper network decay to force
phone customers onto fiber. In recent months, Verizon
has filed notices with the FCC that it seeks to retire its copper
network in six wire centers…
The Move to Fiber Optics is the Next Big Push in the Industry
Fiber Optics In The Industry News
Verizon Accelerates Copper Landline Decommissioning;
Ready or Not, Customers Moved to FiOS
Singlemode fiber, as used in telco and CATV
networks, practically has infinite bandwidth.
10. It was simple in the old days. Cable TV Companies did TV and Phone Companies did Phone.
CATV BELL TELEPHONE
11. Why the move from copper wires to fiber optics?
The first copper phone systems were being built around 1880.
It was the next technological leap from the telegraph.
1980’s
• copper wire phone systems were
reaching their zenith!
• Fiber optics were being introduced
2000
• phone companies have squeezed
as much as possible from copper.
• CATV heavily vested in fiber
12. • HD and 4K Streaming Video
• High Speed Internet
• Telephone
• Alarm Systems
• XBox
• Video on Demand
• Homes have more devices using
services like PC’s, notebooks, tablets
and smartphones
• Businesses are also building networks
Today all companies want to provide everything and new players are coming in the game.
13. Most of these wireless service & cell sites
connect back to the network on fiber.
New 4G and Mobile Broadband demands
are being met by high bandwidth fiber
optic cables from receive site to the
network.
14. How fiber optic cables work.
A Laser injects a beam of light into the core of a glass filament. Light travels through the
filament until it reaches the end of the fiber. The light will bend inside the fiber following
what ever twists and turns the fiber makes.
• The Cladding: coats the glass to
increase the reflective sides of the glass
increasing the distance light can travel
in the fiber
• The Core: a very thin
filament of very pure
glass is the transport
medium for the light. • The Coating: several plastic
coating to protect the glass
15. How light measured in fiber optics?
• Wavelength of light measured in nm (nanometers)
• Power of light measured in dBm (decibels)
• Light loss is measure in dB (decibels)
Fiber Optic Laser Spectrum
16. 1 nanometer =1.0 × 10-9 meters
or
0.000000001 meters
If you divided 1 meter by 1 billion.
That is the length of a nanometer.
17.
18. You will find a broad variety of fiber optic equipment while working In the
telecommunications industry.
