2- In its simplest terms, fiber optics is a medium
for - carrying information from one point to another
in the - form of light. Unlike the copper form of
transmission, - fiber optics is not electrical in nature.
- A basic fiber optic system consists of a
transmitting - device, which generates the light signal an
optical fiber - cable, which carries the light and a
receiver, which - accepts the light signal transmitted. The
fiber itself is - passive and does not contain any active,
generative - properties
3Today fiber optics is either the dominant medium
or a logical choice for every communication
system.
- Fiber enhances the reliability of networks while
simultaneously increasing transport capacity. - Telcos (Phone Cable) use fiber to connect all
their central offices and long distance switches
because it has thousands of times the bandwidth
of copper wire and can carry signals hundreds of
times further before needing a repeater - Copper wire has limitations and is susceptible to
interference. Fiber Optics has virtually
unlimited potential and is immune to
electromagnetic radiation (EMR). - Security is greatly enhanced due to immunity from
EMR
4Similarities
- Both types of fiber are 125 microns in outside
diameter - Both types of fiber are composed of thin strands
of highly transparent glass - Both types of fiber use infrared wavelengths
which are outside the visible spectrum -

5Types of Fiber Optics? Single-mode Multi-mode
Differences Multimode
Differences Singlemode
- Light travels in the core in
- many rays, called modes
- LED sources at wavelengths of
- 850 and 1300 nm
- Bigger core (Almost always
- 62.5 microns)
- Currently Most common LAN
- fiber - Used only for short
- distances and inside buildings
- Fiber shrinks the core down so small
- that the light can only travel in one ray
- This increases the bandwidth to almost
- infinity
- Laser sources at 1300 and 1550 nm
- Small Core ( 9 microns)
- Currently Used for Long Distances
- applications and outside plant

6Underground Construction 50,000 per mile for a
96 fiber cable Overhead Construction 35,000
per mile for a 96 fiber cable
7Installation Types (Underground vs. Overhead)
- Advantages/Disadvantages of Underground
Installation - No Annually Recurring Pole Attachment Fees
- Initial Construction Costs higher
- Rodents are a problem (Pulled conduit or armored
cable can relieve issue) - Earthquakes
- Advantages/Disadvantages of Overhead Installation
- Initial Construction Costs less expensive than
underground construction - Annually Recurring Pole Attachment Fees (15-45
per pole per year) - Ice Storms
- 4. Tornados

8- Fiber to the Curb (FTTC). Depends on copper
wires or coaxial cable for last mile delivery - Fiber to the Node (FTTN). Depends on copper wires
or coaxial cable for last mile delivery
9- Hybrid fiber coaxial networks (HFC) Depends on
copper wires or coaxial cable for last mile
delivery - Fiber to the Premises (FTTP). Fiber optic
communications delivery in which the fiber is run
directly into the premises
10- Active Optical Network (AON). Relies on active
electronic equipment to distribute a signal. - Each signal leaving the Central Office is for
that particular customers use
11(PON) is a point-to-multipoint, fiber to the
premises network architecture in which unpowered
optical splitters are used to enable a single
optical fiber to serve multiple premises
- PON vs. Point to Point Switched Ethernet
- 80 to 85 of all FTTH deployments in North
America are PON - GPON (ITU standard) versus GE-PON (IEEE standard
) - BPON or GPON, V/s GE-PON
12- PONStandardsBPON
- Defined in ITU G.939.3

- Defined in IEEE 802.3ah
- Ethernet Protocol
- 1.25 Gb/s Downstream
- 1.25 Gb/s Upstream

- ATM or Ethernet (GEM) Protocol
- 2.488 Gb/s Downstream
- 1.244 Gb/s Upstream
- 20 KM max from CO/HE to subscriber
13- Optical signal distributed from a central office
from an optical network. At the customer premises
optical network terminals (ONTs) convert the
optical signal into a electrical signal
14Have two fibers but need more, Technology exists
to multiplex fibers from one fiber up to 32
fibers with minimal db loss.
15- Provide for offsite backup
- Offset the costs for future bandwidth needs
- Provide high speed connectivity by utilizing a
combination of proposed fiber segments and
wireless hops - A number of studies rank the United States from
15th to 24th in penetration and broadband speed.
16- The status of broadband and its impact on small
business was the subject of a recent Senate
hearing. FCC Commissioner Michael Copps testified
that in many cases small businesses cant get
connectivity and, when they can, it often is
pricey.

18Affordable High Speed information access is key
to economic development. The proposed project
will help the Cities by
- Attracting new companies into the area
- Retain existing employers
- Improve the overall Quality of life of all
residents -

- Bandwidth! Bandwidth! Bandwidth!
- As a minimum, provide a fiber optic backbone for
WI-FI back-haul.
22HENDRICKS REGIONAL HEALTH (HRH) HOSPITAL
DANVILLE, INDIANA
23The project was divided into three parts
- Connect all four campuses with a fiber optic
backbone - Connect backbone to the Data Center or Point of
Presence (POP) for offsite backup and Internet
access - Procure system electronics
24Henry Street Data Center - Point of Presence (POP)
- WORLDCOM
- GLOBAL CROSSING
- ATT
- MCLEOD
- WILLIAMS
- TIME WARNER
- QUEST
25- Children must be given the tools to
- adequately prepare for entry into highly
- competitive global market.
- Connecting Public Libraries
- Research
- Distance Learning
26- Improving Public Safety (POLICE)
- Monitor Parks, Traffic, Schools
- Monitor Water Treatment Plants
- Increase Coordination between various
- departments
- Hospitals
- Schools
- Fire / Water
- Government Offices
- Utilities
27- Connect HRH sites with a High-Speed Backbone (
10 Giga bits/sec) - Provide High Speed data communications for
- Medical imaging
- Radiology
- Telemedicine
- MRI
28- Most providers will only lease bandwidth
- Some providers will Build fibers at your cost,
give you a small number of fibers and keep the
rest
29- Must have a Competitive Local Exchange Carrier
License (CLEC) to be in the Public Right of Way - Maximum IRU obtained will be 20 years, although
the life of a fiber optic cable is 30 years - Contract may be very restrictive
30- State laws prohibit building fibers in the Public
Right of Way unless you have a CLEC license - Cannot Co-locate in central office of a telephone
company
31- Cannot Build your own backbone you can get a 20
year IRU under a third party CLEC License. At
the end of the IRU agreement the fiber reverts
back to the original owner and the Organization
has to then re-negotiate for use of the fiber. - Every time you want to build a new segment of
fiber, you will have to pay a CLEC licensed
company for use of their license
32- Do your home work. Some providers with excess
fibers will lease you dark fibers - Hire an experienced Telecommunications Attorney
- Hire an experienced consultant
33- Co-locate agreement
- Bandwidth Purchase
- Maintenance Agreements
34The HRH Business Model
35- Expand existing bandwidth for present and future
needs - Offset costs for future bandwidth needs
- Enhance information security by providing
off-site data storage
36- Purchase Bandwidth or buy/install fiber optics
for the primary communication between campuses???
37Cost of 96 fibers vs. 12 fibers
- Construction costs identical
- Cost/mile 96 fibers _at_ .90/ft 4,752
- Cost/mile 12 fibers _at_ .41/ft 2,165
- Cost differential for 18 miles 46,566
38- Allay construction costs by leasing spare fiber
capacity to governmental/commercial entities - Local governments can provide public safety and
educational broadband access - Commercial access to broadband can spur economic
development - Providing reasonable fiber optic access creates
community good will.
