New Fiber Supervision Technique for Passive Optical Networks Supporting Mobile Services

Abstract: In this letter, we propose a new fiber supervision technique for passive optical networks (PONs). The new approach allows for real-time in-service fiber fault detection and localization at any individual fiber in the PON even after high splitting ratios and optical amplifiers without optical distribution network modifications. It consists of real time permanent power monitoring of dedicated supervision wavelengths transmitted between the central office and each remote location. This new proposal relies on synchronized clocks between the test equipment and the remote devices, thus being adequate for its use in fixed-mobile convergent PONs. This novel technique has been successfully demonstrated in a commercial in-service gigabit PON system with 1:64 splitting ratio.

Integrated architecture of EPON and multi-band ROF links for broadband and ubiquitous in-building networks

Abstract: Integrated architecture of Ethernet passive optical networks (EPONs) and 2.4GHz/ 60GHz-band radio-over-fiber (ROF) links is proposed for versatile in-building networks, providing ubiquitous sensing, high-definition video on demand (VOD) and WiFi services. Experimental results confirm the feasibility of the hybrid network of wireless sensor networks (WSN) and wireless local area network (WLAN).

Abstract: This paper presents a performance analysis approach for OCDMA networks, which takes into account both the physical layer characteristics and random media access schemes. Analysis results demonstrate its effectiveness in characterizing the OCDMA network dynamics.

Named Data Networking over WDM-Based Optical Networks

Abstract: Named data networking (NDN) is a typical implementation of information-centric networking (ICN), which has been widely investigated in recent years for its potential as the next-generation network architecture Optical networks are important as the demand for Internet bandwidth is enormous and they can be used to attain extremely high bandwidth In this article, we study optical named data networking (ONDN), which is a complete solution for NDN deployment over optical networks based on wavelength-division multiplexing (WDM) To the best of our knowledge, this is the first attempt to deploy NDN over optical networks We first introduce the basic network architecture of ONDN, based on which we discuss the intuitive packet routing and forwarding approach in ONDN, and propose an innovative alternative to improve network performance In our proposed approach, a novel packet type, called a response packet, is proposed to reserve wavelength along the routing path for data transmission Packet aggregation in ONDN is discussed to improve the efficiency of wavelength utilization In addition, the optical node structure of ONDN is developed and discussed to support all functionalities proposed in this article

MEMS technology for optical interconnect and networking applications

Abstract: The Internet has brought and keeps bringing an explosion of bandwidth that can only be accommodated through the use of optical networking. At the same time there is an evolution in the network, from static point to point WDM links to future all optical mesh networks, where lightpaths may be quickly switched on demand. This change is forced by the demands of the carriers and their clients for new services such as rapid provisioning or bandwidth-on-demand and by considerations of power, costs, bit rate and protocol transparency. However, optical networking today is severely handicapped by the unavailability of high-performance, low-cost optical components. Developing low-cost methods for fabricating large optical switches and tunable lasers is key towards the realization of the all-optical network vision. MEMS play a crucial role in enabling these devices to be realized. Large-fabric optical switches are one of the key application areas for MEMS, but MEMS technology is also finding its way into small-scale switches, variable optical attenuators, and tunable lasers and filters.
