A cost-effective ROF system employing FBG and DML to generate optical mm-wave

We have investigated and experimentally demonstrated a ROF system employing FBG and low-cost DML to generate optical mm-wave. We employ FBG because the bandwidth of the optical modulator is largely reduced and the architecture of the ROF system is simpler. Because no expensive broadband external modulator is used, the overall system is considered as a cost-effective solution. This novel scheme employs low-cost DML to generate mm-wave signal which is a practical scheme to be applied for future broadband access networks. Full Text: PDF References L. Xu and T.

Call for Papers: Optical Code Division Multiple Access

Call for Papers: Optical Code Division Multiple Access Guest Editors Alan Willner, University of Southern California Janet Jackel, Telcordia Submission Deadline: 1 November 2006 Optical code division multiple access (OCDMA) is a technique in which each network user is assigned a unique code rather than a specific wavelength or time slot. This approach allows the same available bandwidth to be shared among the various users, and the code assignments can be flexibly and dynamically changed. CDMA is, of course, quite valuable in wireless systems and had been explored in the optical domain since the mid 1980s. Recently, OCDMA has received increased attention because of significant advances in the enabling technologies, optimal coding schemes, and efficient network algorithms. Due to the increase in interest and the number of published articles in OCDMA, it was felt that the time was ripe for a special issue in the Journal of Optical Networking (JON) on the topic. The research community has demonstrated advances in synchronous and asynchronous systems, based variously on manipulation of phase, frequency, time, and wavelength. A critical question remains as to the ultimate utility of OCDMA, as opposed to or in addition to time and wavelength multiplexing approaches. Applications have been proposed, ranging from PONs for FTTX to the use of codes for flexible networking and for augmented security. This special issue focuses on the technology of OCDMA and on its applications, including its use in networks, possible coexistence with other types of communications, and issues relating to the control and management of networks that incorporate OCDMA. Scope of Submission We welcome submissions on topics including, but not limited to: Novel coding concepts, algorithms, and constructions Synchronous and asynchronous implementations OCDMA-enabled network architectures, topologies, and protocols Enabling hardware Demonstrations of OCDMA Analysis of system performance enhancements Applications of OCDMA and its core technologies Key issues affecting use of OCDMA for privacy and security Comparison and coexistence of OCDMA with other multiuser schemes Manuscript Submission To submit to this special issue, follow the normal procedure for submission to JON, indicating ``OCDMA' in the ``Comments' field of the online submission form.

Models of Restoration Probability in WDM Networks Employing Active Restoration

The ever-increasing demand for network bandwidth makes network survivability an issue of great concern. Lightpath restoration is a valuable approach to guaranteeing an acceptable level of survivability in WDM optical networks with better resource utilization than that of its protection counterpart. Active restoration (AR) is a newly proposed lightpath restoration scheme [M. Mostafa et al. OSA Journal of Optical Networking, vol. 3, no. 4, pp. 247–260] that combines the best of protection and reactive restoration while avoiding their shortcomings. In this paper, we conduct detailed performance analysis on the restoration probability of AR-based WDM networks. In particular, analytical models of restoration probability are developed respectively for networks with full-wavelength conversion capability and for networks without wavelength conversion capability under different backup path searching schemes. Based on the new models, we investigate the effects of wavelength availability, wavelength conversion capability, path length as well as backup path seeking methods on the restoration probability.

Call for Papers: Convergence

Call for Papers: Convergence Guest Editors: Thomas E. Darcie, University of Victoria Robert Doverspike, AT&T Martin Zirngibl, Lucent Technologies Coordinating Associate Editor: Steven K. Korotky, Lucent Technologies Submission Deadline: 1 January 2006 The Journal of Optical Networking (JON) invites submissions to a special issue on Convergence. Convergence has become a popular theme in telecommunications, one that has broad implications across all segments of the industry. Continual evolution of technology and applications continues to erase lines between traditionally separate lines of business, with dramatic consequences for vendors, service providers, and consumers. Spectacular advances in all layers of optical networking-leading to abundant, dynamic, cost-effective, and reliable wide-area and local-area connections-have been essential drivers of this evolution. As services and networks continue to evolve towards some notion of convergence, the continued role of optical networks must be explored. One vision of convergence renders all information in a common packet (especially IP) format. This vision is driven by the proliferation of data services. For example, time-division multiplexed (TDM) voice becomes VoIP. Analog cable-television signals become MPEG bits streamed to digital set-top boxes. T1 or OC-N private lines migrate to Ethernet virtual private networks (VPNs). All these packets coexist peacefully within a single packet-routing methodology built on an optical transport layer that combines the flexibility and cost of data networks with telecom-grade reliability. While this vision is appealing in its simplicity and shared widely, specifics of implementation raise many challenges and differences of opinion. For example, many seek to expand the role of Ethernet in these transport networks, while massive efforts are underway to make traditional TDM networks more data friendly within an evolved but backward-compatible SDH/SONET (synchronous digital hierarchy and synchronous optical network) multiplexing hierarchy. From this common underlying theme follow many specific instantiations. Examples include the convergence at the physical, logical, and operational levels of voice and data, video and data, private-line and virtual private-line, fixed and mobile, and local and long-haul services. These trends have many consequences for consumers, vendors, and carriers. Faced with large volumes of low-margin data traffic mixed with traditional voice services, the need for capital conservation and operational efficiency drives carriers away from today's separate overlay networks for each service and towards "converged" platforms. For example, cable operators require transport of multiple services over both hybrid fiber coax (HFC) and DWDM transport technologies. Local carriers seek an economical architecture to deliver integrated services on optically enabled broadband-access networks. Services over wireless-access networks must coexist with those from wired networks. In each case, convergence of networks and services inspires an important set of questions and challenges, driven by the need for low cost, operational efficiency, service performance requirements, and optical transport technology options. This Feature Issue explores the various interpretations and implications of network convergence pertinent to optical networking. How does convergence affect the evolution of optical transport-layer and control approaches? Are the implied directions consistent with research vision for optical networks? Substantial challenges remain. Papers are solicited across the broad spectrum of interests. These include, but are not limited to: Architecture, design and performance of optical wide-area-network (WAN), metro, and access networks Integration strategies for multiservice transport platforms Access methods that bridge traditional and emerging services Network signaling and control methodologies All-optical packet routing and switching techniques Manuscript Submission To submit to this special issue, follow the normal procedure for submission to JON, indicating "Convergence feature" in the "Comments" field of the online submission form. For all other questions relating to this feature issue, please send an e-mail to jon@osa.org, subject line "Convergence."
