Fiber Access Assertions > Ethernet will be Everywhere > Residential , Business and Backhaul services will converge to single infrastructure > Fiber will progressively replace copper in the access to cope with traffic increase > New cable laying remains the #1 cost , thus PON technologies which optimize usage of the existing fiber are key > But legacy TDM PON (GPON) is not Future Proof and is not well suited to converged Residential/Business/Backhaul infrastructure > OPEX considerations are critical in the Last Mile NextGen Fiber Access solutions required for continued Service Evolution and Innovation 6 Nortel Confidential Information
