New Monitoring Concepts for Optical Access Networks

摘要

New integrated monitoring concepts for physical layer supervision of optical access networks are presented. Network faults and outage times are mainly originated by drifts and degradations of parameters on the physical layer. Simple remotely controlled integrated measurement systems will help network operators improve network quality and reliability and save operational costs. In addition to supervision under the performance parameters of active network components, the optical fiber plant itself will be supervised by an embedded fiber monitoring system in future. We present the functionality of a demarcation point monitor as a new network element which provides information about network availability up to the home network. The operation and the performance parameters of the new monitoring systems are described, and the compatibility with the transmission system is shown in detail. Finally, the additional expenditures and the benefits for the operator are discussed.
