Switched DWDM Ethernet Passive Optical Networks
نویسنده
چکیده
The IEEE Ethernet Passive Optical Networks (EPON) standard is a leading Time Division Multiplex (TDM) standard for PONs. The paper investigates the operation of an EPON based system in a Dense Wavelength Division Multiplex (DWDM) environment. It extends the concept of a multi-wavelength system from being merely a stack of independent PONs to that of a stack of a switched set of PONs. The functioning of the switching elements within the scope of EPON operation are investigated and qualitatively described. The architecture of the “Switched DWDM EPON” system is presented.

A Di erentiated Optical Services Model for WDM Networks
This article addresses the issues of scalable end-to-end QoS in Metropolitan DWDM networks serving as transit networks for IP access networks. DWDM o ering few wavelengths have in the past been deployed in backbone networks to upgrade point-to-point transmission where sharing is based on coarse granularity. This type of DWDM backbone networks o ering few lightpaths, provides no support for QoS ...
متن کاملCase Study for a GPON Deployment in the Enterprise Environment
Enterprise networks are facing disruptive change caused by the use of Internet versus enterprise based applications, increasing video content, integration of voice services onto the LAN, and the transition from wired to wireless LANs. This paper explores this opportunity to adopt Passive Optical LANs (POLs), based on Gigabit Passive Optical Network technology (GPON), rather than continuing with...
متن کاملlambdaMON - A Passive Monitoring Facility for DWDM Optical Networks
This paper presents lambdaMON a novel approach to passive monitoring of very high performance optical networks based on dense wavelength division multiplexing (DWDM). The approach offers very attractive cost/benefit scaling properties, which are further refined by introducing state-of-the-art transparent fiber switching equipment. The rapid pace at which we intend to implement lambdaMONs opens ...
متن کاملEnabling next Generation Ethernet Access with Ethernet Passive Optical Networks
This article describes Ethernet Passive Optical Networks (EPONs), an emerging local subscriber access architecture that combines low cost point-to-multipoint fiber infrastructure with Ethernet. EPONs are designed to carry Ethernet frames at standard Ethernet rates. EPONs use a single trunk fiber that extends from a central office to a passive optical splitter, which then fans out to multiple op...
