Comparative evaluation of optical amplifiers in passive optical access networks

In this paper, the parameters of optical amplifiers are evaluated using numerical methods with the Optisystem software. The main objective of this evaluation is the implementation of an optical telecommunication architecture, able to push back the current limits, due to a more and more restricted bandwidth following a demand which does not stop growing. We start from a study of the classical architecture of an optical telecommunication network with an external modulation provided by the mach zehnder modulator, the non return to zero (NRZ) coding, a pseudo random bit generator and a continuous wave (CW) laser diode of frequency 193.1 THz. The results obtained show a transmission possibility at 30.8 dBm and an output power of 25 dBm (316 mW) with an electrical rate signal to noise (SNR) and optical rate signal to noise (OSNR) beyond 34 dBm. The successive integration of the different amplifiers will improve these results with a gain of more than 10 dBm and also provide a better signal quality.

The Campus as a Smart City: University of Málaga Environmental, Learning, and Research Approaches

For the past few years, the concept of the Internet of Things (IoT) has been a recurrent view of the technological environment where nearly every object is expected to be connected to the network. This infrastructure will progressively allow one to monitor and efficiently manage the environment. Until recent years, the IoT applications have been constrained by the limited computational capacity and especially by efficient communications, but the emergence of new communication technologies allows us to overcome most of these issues. This situation paves the way for the fulfillment of the Smart-City concept, where the cities become a fully efficient, monitored, and managed environment able to sustain the increasing needs of its citizens and achieve environmental goals and challenges. However, many Smart-City approaches still require testing and study for their full development and adoption. To facilitate this, the university of Málaga made the commitment to investigate and innovate the concept of Smart-Campus. The goal is to transform university campuses into “small” smart cities able to support efficient management of their area as well as innovative educational and research activities, which would be key factors to the proper development of the smart-cities of the future. This paper presents the University of Málaga long-term commitment to the development of its Smart-Campus in the fields of its infrastructure, management, research support, and learning activities. In this way, the adopted IoT and telecommunication architecture is presented, detailing the schemes and initiatives defined for its use in learning activities. This approach is then assessed, establishing the principles for its general application.

Design and development of electronics for the EuXFEL clock and control system

The development of the Clock and Control (CC) hardware and firmware for the EuXFEL DAQ system is presented. The system exploits the data handling advances provided by the new telecommunication architecture standard for physics. The CC is responsible for synchronising the DAQ system to overall system timing. The hardware consists of a DESY designed MTCA.4 board and a UCL designed Rear Transition Module (RTM). Each RTM controls up to 16 Front End Modules (FEMs) for a 1 Megapixel 2D detector. The CC system is designed to provide extendibility and scalability to support future upgrades to the DAQ or larger detectors.

You Must Have Been at A Different Meeting: Enacting Culture Clash in The International Office of the Future

This article introduces a new concept for exploring the design of IT infrastructure in transnational organizations. This concept is simulation gaming that uses so- called synthetic national culture profiles. The paper describes a game in which a telecommunication architecture was designed for a multinational company. It concludes that synthetic cultures are a powerful tool for generating awareness about the profound potential effects of differences in national culture within multinationals.

Improving reliability through architecture partitioning in telecommunication networks

The paper presents a new switching architecture to improve telecommunications reliability. The architecture is partitioned depending on the type of network used, reliability requirements, and expected traffic in the network. The partition size depends on the network reliability, bandwidth, and traffic. A reliability model for a telecommunication architecture is used to partition the network and to improve end-to-end reliability. The model defines critical components in the networking architecture and their connections. The component connections permit the propagation of faults from the component in which the fault originates to the other components. This propagation can cause failures in the chain (or in the tree) of components. The partitioned architecture limits the propagation of faults, simplifies fault detection, and preserves reliability of the remaining partitions. Examples of different networks are used to show the applications of the model. >

Hermes system: Preliminary telecommunications architecture system

Many Hermes spaceplane communication and navigation needs can be met with existing, under development and planned means such as domestic satellites, global positioning system and European data relay satellites. This paper presents the first preliminary telecommunication architecture of the Hermes system, the chosen approach, major assumptions and main link budgets; a functional diagram summarizes this architecture with its links and nodes.
