3. Definition :The optical fiber system
serves as a simple connection between
two sets of electrical signal processing
equipment .This type of interconnection
between the optical systems is known as
“fiber optic networking”.
FIBER OPTIC NETWORKING
5. The technology used for the
implementation of fiber optic
networking is Dense Wavelength
Division Multiplexing (DWDM)
EVOLUTION:
6. Methods of Multiplexing :Methods of Multiplexing :
Wavelength Division Multiplexing –
• Multiplexes multiple optical carrier signals on a single optical
fiber by using different wavelengths (colors) of laser light.
• Allows multiplication in capacity.
• Enables bidirectional communications over one strand of
fiber.
7. Frequency Division MultiplexingFrequency Division Multiplexing ––
• AssignsAssigns non-overlapping frequencynon-overlapping frequency ranges to different signals orranges to different signals or
to each "user" of a medium.to each "user" of a medium.
8. The key requirements for the DWDM systems
in the networking include the following:
Multi protocol support
Scalability
Reliability and availability
Openness (interfaces,network management)
Ease of installation and management
Size and power consumption
Cost effectiveness
9. The advances in the optical infrastructure of
the DWDM technology.
10. ADVANTAGES OF DWDMADVANTAGES OF DWDM

Dynamic provision
Fiber capacity
DWDM will continue to provide the bandwidth for large
amounts of data
The capacity of the system can be increased with the
growth of technology.
