Current and next-generation passive optical networks monitoring solution

Abstract: In order to enable new services that require high data rates over longer distances, the optical fiber substitutes the copper cable step by step in the access network area. Time division multiplexed Passive optical network (TDM-PON) is a fast emerging architecture that uses passive components only between the customer and the central office. PON operators need a monitoring system for the physical layer to guarantee high service quality. This monitoring system is necessary during the fiber installation, final testing, regular operation of the network, and for fault localization. In this paper, we present our monitoring system based on optical coding for PON maintenance. This system has almost all the monitoring features required by a network operator. We explained the design and the principle operation of the technique. Moreover, we presents a management and protection solution for long-reach PON networks. Our system design achieves high reliability performance with almost half the cost if full network protection is used.

More light in Polish optical fibers

Abstract: Optical communications infrastructure is undergoing an intense development in his country now. A number of international investors and domestic operators are building from the beginning, modernizing or developing proprietary network or leasing wide area systems on a large scale. The aggregate level of these processes is of the order of bil $. Despite of this the network is not homogeneous, has not satisfactory bandwidth, lacks the QoS, has inadequate international connections, and (according to prevailing opinions) the prices are too high for corporate as well as private users. The intense development of the optical infrastructure is governed by two dominant tendencies: burying new large, fat, optical pipes--cables containing even as much fibers as 500 (for C, L and XL optical bands) and investments in DWDM for main traffic directions (previously working in 1300 nm band).

Architecting a national optical fiber open-access network: The Australian Challenge

Abstract: In this article we discuss the challenges faced when building a national optical access network that is ubiquitous (i.e., reaches all households nationwide) and open access (i.e., allows any provider to offer their services over it). Our work is inspired by a public fiber access network being built in Australia called the National Broadband Network (NBN) that will deploy fiber to 93 percent of premises, providing broadband access at potential data rates of 100 Mb/s and above. We highlight how the nationwide open access nature of the network creates new architectural challenges, in terms of both fiber layout as well as interconnection with private providers competing to offer retail services. We identify some of the technical choices related to the support of advanced features such as quality of service, multicast, and reliability, and discuss potential challenges providers may face when rolling out their services in such a network.

Optical access networks

Abstract: Passive Optical Networks (PONs) are emerging as the ultimate solution for high speed access networks. All-fiber components are ideal for passive optical networks because of many inherent advantages such as low forward and return losses and high power handling capability. This chapter reviews the architecture and optical component technologies used in PON. This chapter also presents the relevance of the research work.
