The Challenge:
The communication’s
revolutions-
LASER &Fiber Optics
Principle implemented-
Total internal reflection
Advantage over its
Predecessor-
greater bandwidth
Wavelength conversion in optical networks:
Categories of Wavelength conversion
No conversion
Full conversion
Limited-
conversion
Fixed conversion
Sparse wavelength conversion
Concluding notes:
Possibility of coexistence of
two optical layers
Survival of SONET
The next big challenge –
managing 100+ wavelength
