Transport Network Technology Evolution – Physical Medium
• Microwave Transmission & Transport Network
• Boom in data services (HSPA+ / LTE) drives the needfor Fiber Optic deployment in Backhaul and even inAccess layer.
•Dense Wavelength Division Multiplexing (DWDM)technology evolves from nx2.5/10/40Gbps and soon tonx100Gbps per fiber pair.
• NG-DWDM incorporating L2 functionality is already arealit .
4 29 March 2010Mobile Technology Evolution
• Passive Optical Network (PON) and NG-PON in theAccess network permitting to further increase capacityby providing 1 Gbps connectivity for each customerexpected 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 usuallyup to 6)
• Evolving to SDH and NG-SDH overFiber
• 2.5 Gbps and 10 Gbps
• Su ort of Ethernet services

(mapped over TDM networks)
• Packet Switching – IP technology
• Using mainly IP/MPLS both in thecore and in the Backhaul parts of thenetwork.
• Carrier Ethernet also an option forbackhauling purposes.
• Trying to handle the packet trafficexplosion and the strain in theBackhaul networks.
