  • An Absolute QoS Framework for Loss Guarantees in Optical Burst-Switched Networks

    <para> In order to meet the requirements of real-time applications, optical burst switched backbone networks need to provide quantitative edge-to-edge loss guarantees to traffic flows. For this purpose, there have been several proposals based on the relative differentiation quality of service (QoS) model. However, this model has an inherent difficulty in communicating information about internal network states to the edge in a timely manner for making admission control decisions. In this paper, we propose an absolute QoS framework to overcome this difficulty. The key idea is to offer quantitative loss guarantees at each hop using a differentiation mechanism and an admission control mechanism. The edge-to-edge loss requirement is then translated into a series of small per-node loss probabilities that are allocated to the intermediate core nodes. The framework includes a preemptive differentiation scheme, a node-based admission control scheme, and an edge-to-edge reservation scheme. The schemes are analyzed and evaluated through simulation. It is shown that the framework can effectively offer quantitative edge-to-edge loss guarantees under various traffic conditions. </para>

  • Wired, Wireless, and Optical Systems

    This chapter deals with the basic principles of telecommunication transmission systems, which employ wired cabling, wireless or radio signals, and fiber‐optic light transmission, and explains the salient points of each approach. It helps the reader to understand the importance of frequency and bandwidth in relation to a telecommunication system. The chapter also deals with various digital line codes used for synchronization, and also explains their purpose. It discusses the nature of a transmission line and shows how standing waves are produced. The chapter explores the general principles of radio propagation, and then explains the method by which antennas transmit or receive a signal. It also explores the principles of optical communications, including light generation, propagation through optical fiber, reception, and synchronization. The chapter applies knowledge of wireless and light propagation to transmission system loss calculations.

  • Optical Fiber Effects

    Wavelength division multiplexing (WDM) transmission heavily depends on the fiber type that is used, and the related transmission effects and characteristics. Single‐mode fibers are transmission systems that show frequency dependence (i.e., the pulse response is not the Dirac delta function), time variance, and weak nonlinear behavior. The resulting transmission impairments are as follows: Linear effects such as, attenuation (intrinsic loss, bending loss), polarization‐dependent loss (PDL), chromatic dispersion (CD) due to material waveguide, and profile dispersion. These dispersion mechanisms lead to group‐velocity dispersion (GVD) and dispersion slope or higher order CD. Nonlinear effects include self‐phase modulation (SPM), cross‐phase modulation (XPM, IXPM), four‐wave mixing (FWM, IFWM), modulation instability, nonlinear phase noise (NLPN), cross‐polarization modulation (XPolM), stimulated Raman scattering (SRS) and stimulated Brillouin scattering (SBS). For WDM long‐haul transmission, this chapter considers all these effects and their interactions.

Next there will be a discussion of testing dissimilar connectors and potential problems with mismatched end polishes on singlemode connectors. The final chapter explains the roles of components causing reflections and how the test to measure the amount of reflectance in a span is performed.

  • Realization of single-moded broadband air-guiding photonic bandgap fibers

    In this letter, we propose a novel type of air-guiding photonic bandgap fiber, which exhibits an effectively single-mode operation with a low confinement loss over a wide wavelength range, extended from 1460 to 1840 nm. For several realistic structural parameters, the wavelength dependence of the dispersion as well as the confinement loss properties are investigated through a full- vector modal solver based on the finite-element method. In particular, we optimize the structure so as to exhibit the following performance: effectively single-mode operation from 1460 to 1840 nm, with corresponding confinement loss of the fundamental air-guided mode of 8.8times10<sup>-5</sup> dB/km, and enhancement of the confinement loss of the higher order mode of 43 dB/m for ten-ring structure

  • Metal-based 1X2 Plastic Optical Fiber (POF) splitter for video over POF system application

  • Optimized TEM<inf>00</inf>output from a uniformly pumped four-level laser

    The maximized continuous TEM00output power and optimum output mirror transmission are calculated for a four-level laser assuming spatially uniform pumping of the laser medium. The results are expressed in simple closed forms that depend on the TEM00mode radius, the radius of the gain medium, the absorbed pump power, the threshold absorbed pump power, and the optical loss of the laser resonator.

  • A fiber optic barrier integrity monitor

    A description is presented of two designs for monitoring the integrity of a barrier surrounding a location. The concept was originally developed for verifying compliance to a treaty where the barrier was to surround a site containing treaty-limited items. The application of these designs is not limited to treaty verification and might be used to monitor the integrity of vault walls, building and igloo walls, truck and transport container walls, or net barriers partitioning a harbor. The barrier consists of a row of upright columns supporting three horizontal rails. An optical fiber is threaded through the rails and the continuity of the fiber is monitored via a light signal sent through it. The design is intended to detect any breach immediately so that the violator might be caught in the violation act. The equipment should also detect attempts to tamper with the system by inserting a bypass around a portion of the fiber.<<ETX>>

  • Optical coupling analysis of dual-waveguide structure for monolithic integration of photonic devices

    We proposed the dual-waveguide structure (DWS) with spot size converters and demonstrated the monolithic integration of both photodetector (PD) and electroabsorption modulator (EAM) based on the DWS. The coupling loss between the device facet and a lensed fiber was as small as 2.13 dB. The responsivity of PD and the extinction ratio of EAM were 0.58 A/W and 20 dB at -4 V/sub dc/, respectively. From the optical coupling analysis, it was proved that the dual- waveguide scheme provided one of the best solutions for the monolithic integration of optoelectronic devices.

  • Application of a low-loss criterion to optical waveguides and devices

    Optical waveguides and devices suffer loss due to a variety of nonuniformities. The calculation of the actual loss is usually involved and requires a fair degree of mathematical sophistication. However, if the goal of the waveguide designer is to minimise loss, a well known universal criterion can determine qualitatively whether loss increases or decreases with the variation in each of the waveguide or device parameters. To demonstrate the simplicity and generality of this criterion, it is applied to examples covering: microbending, pure bending, tapering, sinusoidal deformations (fibre gratings), helical fibres and Y-junctions.<<ETX>>
