4. Old vs New
• What if Albert Einstein was here
in this year of 2019?
• Data communication
Technology VS Other

Copper Optical Fiber
Maximum bandwidth of
10 Gb/s
60 Tb/s and beyond.
300 Ft. @ 1,000Mbps 12 Miles+ @
10,000Mbps
5 Years 30-50 Years
10W per User 2W per User
Photons travel at the speed of light, whereas electrons used
in copper travels
at less than 1% of the speed of light.

7. Evolution of fiber optics

8. History
• Discovered by Tyndall
• First used 1950’s
• Kao and Hockham published a paper at 1966
• Available commercially in 1980
• operated at a bit rate of 45 Mb/s and allowed repeater spacing of
up to 10 km

9. Main Sections Of
Fiber Optic Cable
• Main light transmitting section.
➢ Middle position.
• Guide for the light wave that
reflect back light wave into the
core.
➢Made by pure silica.
• Protecting section for core and
cladding from ultra violate
➢Gives cable rigidity.

communication
❑ Step Index:
▪ Single mode
▪ Multimode
❑ Guided Index:
• Single mode step index.
• Multimode Step index.
• Multimode Graded index
Fiber.
1 Microns = 0.001 mm

11. Why It is the best communication system ?
• Enormous potential
bandwidth.
• Small size and Weight
• Total Electrical Isolation

12. • Signal Security
• Low Transmission Loss
• Potential Low cost
Why It is the best communication system ?

13. Need to Improve: Disadvantage side
• High Initial Cost.
• Requires Specialized Maintenance.

14. Development in fiber optic communication
• Material used in fiber optic cable
• Sensor development
• Development in fiber technology in
‘HAPs’

15. Most Application of optical fiber
• Structural Health monitoring
• Industrial Automation
• Civil Structure Monitoring
