Transport Network Technology Evolution � Physical Medium
� Microwave Transmission & Transport Network � Boom in data services (HSPA+ / LTE) drives the need for Fiber Optic deployment in Backhaul and even in Access layer. �Dense Wavelength Division Multiplexing (DWDM) technology evolves from nx2.5/10/40Gbps and soon to nx100Gbps per fiber pair. � NG-DWDM incorporating L2 functionality is already a reality. � Passive Optical Network (PON) and NG-PON in the Access network permitting to further increase capacity by providing 1 Gbps connectivity for each customer expected to be available soon.

Transport Network Technology Evolution � From TDM to IP

� Circuit Switching � TDM technology
� Started with PDH over Microwave (up to 140 Mbps) � Continued with SDH over Microwave n x 155 Mbps (n usually up to 6) � Evolving to SDH and NG-SDH over Fiber � 2.5 Gbps and 10 Gbps � Support of Ethernet services (mapped over TDM networks) � Packet Switching � IP technology � Using mainly IP/MPLS both in the core and in the Backhaul parts of the network. � Carrier Ethernet also an option for backhauling purposes. � Trying to handle the packet traffic explosion and the strain in the Backhaul networks.
