Traditional PON Versus Mixed PON/Active Architectures Based on Ciena’s Universal Aggregation Solution

10G XGS-PON CAPEX- centric Business Case
By deploying a pluggable mixed PON/ active architecture based on Ciena’s Universal Aggregation (UA) solution, network operators can achieve both CAPEX savings and PON reach extension. This white paper develops a business case employing Ciena’s 5170 Packet Networking Platform to quantify the CAPEX.
Introduction The Passive Optical Network (PON) architecture employs shared fibre to achieve cost savings for network operators, which is quite cost-effective over short feeders. However, over long feeders, the Outside Plant/Optical Distribution Network (OSP/ODN) cost for the traditional PON architecture, in which the Optical Line Terminal (OLT) is located at the Central Office (CO) or local exchange, increases rapidly. Also, limitations in system reach/distance due to optical splitting power loss creates a major disadvantage for the traditional PON architecture. Over long feeders, a mixed PON/active architecture enables network operators to achieve: n CAPEX savings n PON reach extension
Ciena’s UA solution summary
Network operators are looking for comprehensive solutions to address their main pain point around deploying PON- based broadband access networks— OSP/ODN cost and PON reach limitation. Figure 1 shows Ciena’s UA solution. This solution provides network operators with increased choice and control of tangible business value assets like coherent optics, pluggable dedicated and shared
