3. What is Optical Communication?
The communication in which light is used to carry the signal to remote end instead of electric current
Optical Communication relies on optical fibers to carry signals to the destination

4. Cont......

5. Advantages & Disadvantages of Optical Communication
Long distance transmission due to low attenuation
OFC is delicate so has o be handlled carefully
Small size and low weight
Communication is not totally in optical domain,so repeated electrical-optical-electrical conversion is needed
Larger information capacity due to wider bandwidth

6. Optical Soliton
Solitons are very narrow, high intensity stable optical pulses.
High peak power and special shapes
During propogation,the shape of soliton remains unchanged.
Soliton pulses reduce the effect of chromatic dispersions.
Chromatic dispersions:
1.Group velocity dispersion
2.Self phase modulation

7. Cont.....

8. Cont...
Group velocity dispersion

9. Cont.....
Self phase modulation

10. Criteria to be satisfied for the soliton
Appropriate peak power
Should be unchirped

11. Soliton based transmission

12. Advantages and Disdavantages
1.Dispersions are reduced
2.Pulse shape can be maintained
3.Transmission speed can be increased
4.Opens the way to ultrahigh speed superhighways

13. Cont
Disadvantage:
Proper power maintenance is a critical issue

14. Conclusion
Soliton based optical fiber communication systems are more suitable for long haul communication because of their very high information carrying capacity.
