3. Abstract
 Transmission of data through laser has been keen interest for the researchers for past
decades in compare of fiber optics and RF transmissions due to its distinctive
advantages such as: Low Cost, convenient installation and maintenance while
supporting high bandwidth and license free communication. Alike other free space
transmissions system FSO the environment and climate can degrade the performance
of the system. Whilst the effect of Fog is maximum on the narrow band transmission of
FSO because the size of particle and the wavelength of laser beam is almost identical.
 However, in this thesis we discussed the advantages and disadvantages of both
technologies. For fiber optics it is already understood that the most reliable solution to
go for is fiber optic but that would take months to install and capital cost is extremely
high. We sourced prices from authenticated sources and confident that these
quotations are valid and practical. For that we have concluded that FSO sure have
some performance issue in adverse weather conditions if not maintained properly
otherwise it’s extremely cost effective, reliable and convenient.

4. Introduction of Project
FSO Intro
 Free Space Optics (FSO) a wireless technology that is used to
transmit voice, video and data in form of light same as fiber optic
but the medium is air.
 It is a broadband technology requires clear line of sight between
two end pairs of FSO transceivers.
 It is completely license free.
 There are reasons to adopt FSO over Fiber optics: Installation cost
and time.
 We compared both technologies side by side in this project and
conclude the suitable choice for University of Sindh Campus Area
Network.

Fiber Optic Intro
 The modern telecommunication systems have grown
exponentially, hence twenty first century is the era of
‘Information Technology’.
 Distinctively, optical fiber has played pivotal role in
providing high quality high-speed telecommunication
systems.
 Undoubtedly fiber optics have achieved extremely high
signaling rates
5

6. Motivation and Need
 Our work is focused on economical and high speed last-
mile solution
 In University of Sindh new project of smart university is
going to implement
 Therefore we researched on ad-hoc FSO system.
6

7. Aims and Objectives
 Provide the comparison at the last mile connectivity of
Sindh university campus between networks of Fiber optic
cable and Free Space optical link.
 Our aim of project is to increase awareness of (FSO) in
Pakistan which is feasible, reliable and convenient against
fiber optics for shorter distance and high speed data
communication.

8. Scope of Project
 Currently a new project of HEC namely (Smart University
Project) is in running phase entitled as smart university
but in our university campus a new setup for ISP is also in
installation phase. Furthermore, the internet connectivity
will also be provide at hostel and other campus. Our
project is based on last mile connectivity of that network,
which provide point-to-point connectivity for around 5 t0
6 Km with high data rate and license free link in the
optical nature of signal.

9. Tools and Technologies
 Matlab (For losses calculations)
 Realistic quotations for FSO and Fiber optics

10. Design and Development
Methodology
 We are working in physical layer of the network
 Fiber optics and FSO are kept side by side
 The losses of FSO and Fiber optics are keenly observed
through ‘Matlab’ simulations.
 We also get price quotations of the equipment from
authenticated sources

and for the longer links (2km, 4km) goes up to USD 15 –
20,000 That’s a lot cheaper than digging fiber optics.
 Note: The major cost in fiber optics is digging + trenches
trenches + ducts.
 And time: Planning a fiber dig in a major cities takes
months to complete
16

17. Final Results
 By calculating the losses of Fiber optics and FSO we have
concluded that its rare that FSO link could get terminated
should the distance be in between 2kms.
 On the contrary Fiber optics have losses so small that are
almost negligible
 Both have almost same datarate
 By taking quotations side by side we found that FSO
system could cost 70% less than fiber optic plus no
maintenance cost will incur

20. Conclusion
 The purpose of this project is to find out the overall
sufficient solution for “Smart University” a project of
University Of Sindh main campus.
 Two choices for last-mile connectivity is considered first
one is Fiber optic, which may be the best solution if the
capital cost, maintenance and total deployment time took
aside. The second choice which we propose is using Free
Space Optics system (FSO) which gives exactly the same
functionality as Fiber optics but is low cost and ad-hoc in
nature
 FSO is better solution in terms of cost and deployment
time which is roughly ~ 7 days .
20

21. Future Work
 In near future wireless technologies will be more
affordable and considered to install rather using
conventional cables. Therefore, research and awareness
of such technologies in Pakistan is a dire need.
