Fiber Access Networks: Reliability Analysis and Swedish Broadband Market

Fiber access network architectures such as active optical networks (AONs) and passive optical networks (PONs) have been developed to support the growing bandwidth demand. Whereas particularly Swedish operators prefer AON, this may not be the case for operators in other countries. The choice depends on a combination of technical requirements, practical constraints, business models, and cost. Due...

Reliability and Cost Benefit Analysis of Protection Schemes for Passive optical Fiber Network

This paper gives a model for finding the reliability and cost of passive optical fiber networks (PONs). Mathematical modeling of various PONs has been done using to determine the cost and reliability for deployment at the access domain. It is observed that there is a trade-off between cost of protection and the reliability level that we attain from adding redundancy, as duplication in PON netwo...

Reliability versus Cost in Next Generation Optical Access Networks

Design of Access Network System Based on EPON

Recently, with the development of internet, the requirement of bandwidth is increasing crazily. Since optical fiber has lager bandwidth and superior transmission capability than common copper local access solutions, it is more and more widely employed by access network. This paper proposed a high reliable system for access network in EPON. It is composed with NMS, DSS, OLT and ONU. Besides, to ...

Self-Healing Hybrid Protection Architecture for Passive Optical Networks

Expanding size of passive optical networks (PONs) along with high availability expectation makes the reliability performance a crucial need. Most protection architectures utilize redundant network components to enhance network survivability, which is not economical. This paper proposes new self-healing protection architecture for passive optical networks (PONs), with a single ring topology and ...
