The application of a recently demonstrated mode-locked ultralong pulsed fibre ring laser architecture (Gallazzi et al., 2021) to the inexpensive and efficient generation supercontinuum from output at 1.56 μm in standard single-mode telecommunication is experimentally demonstrated. impact broadening fibre, dynamic switching between different harmonic modes influence polarization on properties ge...

The purpose of this study is to investigate the factors contributing brand switching and how product quality can help maintain brands competitive position in market. direct relationship with was measured through mediators customer satisfaction image. data collected from 300 top-tier consumer brands. Findings show that availability perception are intrinsically tied service or quality. results de...

By using two main effects of cross-gain modulation and cross-phase modulation in semiconductor optical amplifier-based devices, many logic functions of logic AND, OR, XOR, NOR and XNOR are successfully demonstrated. Also, complex systems including all-optical half and full adders in a combination of multiple logic functions are successfully demonstrated. These functions will provide not only in...

Large software systems evolve slowly but constantly. In this paper we examine the structure of several releases of a telecommunication switching system (TSS) based on information stored in a database of product releases. We tracked the historical evolution of the TSS structure and related the adaptations made (e.g. addition of new features, etc.) to the structure of the system. Such a systemati...

Modern telecommunication networks are designed to support converged traffic including voice, data and video. [1] One major feature of these networks is that the input traffic is usually highly bursty.[2] Also, because these networks operate in a packet switching mode, there is usually a strong correlation between packet arrivals. Thus, for these networks the traditional Poisson traffic model ca...

In the computer market open interfaces have paved the way for intense competition with dynamic and rapid market evolution as a result. Open switch interfaces could in a similar way change the market conditions for the switch and router industry and in addition result in a more diversified telecommunication market. This Invited Lecture provides an overview of the new system architecture that the...

The basic concepts of the ultrafast optoelectronic interface for superconducting digital electronics are presented. Several implementations of both the input optical-to-electrical and the output electrical-to-optical transducers are discussed. As an example, an optoelectronic telecommunication router is used that is capable of switching signals at a >100 Gbit s−1 rate on a single wavelength. We...

Today's requirements engineering approaches focus on notation and techniques for modeling the intended functionality and qualities of a software system. Little attention has been given to systematically understanding and modeling the relationships between business goals and system qualities, and how these goals are met during architectural design. In particular, modeling must encompass changes ...

A simple, high-performance ATM switch architecture for the public telecommunication services has been proposed. The switch has strictly internal nonblocking architecture which provides virtually no cell loss using the internal speedup. To reduce the size of BGT (Broadcasting and Group Translation) tables, we have proposed the rounding copy network which consists of cascaded copy modules to prov...
