Ethernet-based passive optical local-area networks for fiber-to-the-desk application

Abstract: We introduce optical local-area network (LAN) architectures based on multimode optical fiber and components, short wavelength lasers and detectors, and the widely used fast Ethernet protocol These architectures are designed to lower the costs associated with passive optical LAN implementation Further reduction in overall cost is achieved through decreased network downtime, lower maintenance cost, extended geometrical spans, and larger headroom for future capacity increase These optically transparent networks represent a novel approach for implementing fiber-to-the-desk

The optical network control plane: state of the standards and deployment

Abstract: The notion of an optical control plane has rapidly ascended from being a mere concept to a detailed set of protocol standards developed with broad industry participation. In this article we present a brief overview of optical control plane architecture and the associated protocols. We then examine the business drivers and inhibitors behind the optical control plane effort, the current state of the standards, interoperability status, and the open issues that need to be resolved before widescale deployment of this new technology can begin.

Cost-minimized design for TWDM-PONbased 5G mobile backhaul networks

Abstract: Dense deployment of small cells would be required to provide for high capacity and universal access to future fifth-generation (5G) mobile networks. However, this would require cost-effective and reliable backhaul connectivity between these small cells. Time and wavelength division multiplexed passive optical networks (TWDM-PONs) are considered a promising choice for this purpose. In this paper,we consider the cost-minimized design of a backhaul network for a 5G mobile system using TWDM-PON. For this, equipment and deployment costs are considered, and the design is based on satisfying network constraints such as the maximum number of subscribers per optical line terminal and themaximumnumber of subscribers per wavelength. Considering the fact that many small cell base stations are dispersed over an extensive wireless coverage, a K-means clustering-based algorithm is proposed for the optimal solution. The strategies of using multistage remote nodes and cable conduit sharing are applied to further reduce the labor cost of trenching and laying fibers. Our simulation results show that the proposed approaches can substantially reduce the backhauling cost in comparison with the traditional intuitive random-cut sectoring approach.

Benefits and requirements of flexible-grid ROADMs and networks [invited]

Abstract: Due to claims of enhanced spectral efficiency and the ability to accommodate future modulation formats, flexible-grid networks in which the center wavelength and passband width of the optical channels can be set on the fly have attracted wide attention. A flexible-grid reconfigurable optical add/drop multiplexer (ROADM) requires more than a flexible-grid wavelength-selective switch, and a flexible-grid network requires far more than flexible-grid ROADMs. We discuss the technologies required to enable flexible-grid networks. We examine the potential benefits of using flexible-grid ROADMs and compare this approach with alternative strategies.

Optical local area network technologies

Abstract: To utilize the large bandwidth of optical fiber, optical LANs must employ architectures that fundamentally differ from current single-channel LAN architectures. With computer processor speeds continuing to grow exponentially and multimedia applications growing even faster, there is a strong need for higher-speed local area networks (LANs) that can handle the traffic generated by tomorrow's LAN users. Optical fiber is well suited for high-speed traffic transport, but the busty nature of computer traffic and large number of users makes it difficult to utilize the fiber's capacity in LANs. The incorporation of multiple payload channels in future LANs is seen as a necessity; WDM is a good candidate for achieving this. The rapidly improving optical component technologies allow more flexible WDM architecture designs for various emerging applications. >
