2. Local Exchange network

3. Types of local exchanges

4. Deployment of wdm

5. WHY ? Deployment of WDM Short Distant Communication ( Few 10 KMs )
Capacity Growth
High Capacity connections

6. DEPLOYMENT OF WDM No. of optical amplifiers between shorter spans
Cost is reduced when Integrated with WDM/SONET
1:1 protection for Physical fiber
1:N protection for SONET systems
Need for higher capacity requirement in U.S.

7. High capacity Provides high capacity connections Different protocols
Different Bit rate
Local Exchange Carrier < Interexchange networks

8. SERVICES Different services offered Multiple networks are deployed
Public network
Private network

9. Disadvantages Traffic distribution changes
Re-arrange of network capacity
Happen frequently

10. Current progress Deployment of DWDM in local exchange carrier networks
Features :
Scalability
Interoperability
Extended Operations
