Passive Optical Network (PON) is the promising technology in future broadband access networks. Protection is an important and imperative issue in PON system while protection of cascaded PON (with two-stage splitter or more) system has been ignored. This paper presents a comprehensive study on protection strategy for cascaded PON system. The reliability and protection issues of cascaded PON are studied...
Passive optical networks (PONs) are considered as a promising solution for broadband access networks. Due to the growing demand for reliable service delivery, fault management in the network is becoming very significant. However, there is a trade off between the cost of protection and the level of service reliability. Since economical aspects are most critical in the access part of the networks, improving...
The paper presents a techno-economic assessment of optical access network upgrade technologies for subscribers with high capacity demands. The major contribution is an in-depth analysis of expected cost benefits and business opportunities of optical broadband alternatives in the mixed residential and business market. The study focused on physical layer upgrades, and examined the installed first costs...
