Digitized-Radio over Fibre (DRoF) techniques provide higher dynamic range and are more robust against optical link impairments. In this paper, a fully-photonic DRoF system is proposed and its performance is investigated in an integrated system with an analogue Radio over Fibre (ARoF) system. In this simulation based evaluation, DRoF and ARoF systems performance in the presence of other channels...

Fibre Bragg gratings (FBGs) are novel components of communication and sensors. The technique commonly employed for production of FBGs involves exposure of photosensitive germanosilicate fibre cores to intense excimer laser radiation through an optical phase mask located in close proximity of the fibre. FBGs were written using this technique in two different fibre samples and their strain and te...

A model of an optical fibre communication line operating at 80 Gb/s with QPSK modulation format is studied numerically. The error statistics and patterning effects are analyzed and nonlinear transmission impairments of the optical signal are quantified.

A dielectric fibre with a refractive index higher than its surrounding region is a form of dielectric waveguide which represents a possible medium for the guided transmission of energy at optical frequencies. The particular type of dielectric-fibre waveguide discussed is one with a circular cross-section. The choice of the mode of propagation for a fibre waveguide used for communication purpose...

The achievable information rates of optical communication systems using ultra-wide bandwidth 100-nm distributed Raman amplification have been investigated for each individual subchannels, based on the first-order perturbative analysis of nonlinear distortions. Introduction To date, optical fibre communications have achieved unprecedented growth and success over the past three decades and now st...

Introduction: Owing to the decreasing cost of powerful integrated circuits, electronic signal processing in digital optical communication systems is receiving increasing scientific and industrial interest. In 10 Gbit=s optical links, such as those used in metropolitan and wide area networks, chromatic dispersion (CD) compensation plays an important role and affects significantly the communicati...

Nowadays 'optical communication' usually means the exchange of information with the aid of optical fibres. The term is also applicable, however, to visual communication by semaphore or similar methods. In France between 1793 and 1852, for example, a visual communication network designed by Claude Chappe was in use. This worked with a system of moving arms that could be viewed by telescope from ...

-Radio-over-Fibre (RoF) is an optical communication technique based on the transmission of standard wireless radio signals though optical Fibre in their native format. The optical Fibre provides a huge bandwidth that can support a variety of wireless systems, regardless of their frequency bands, being protocol-transparent which is reflected in great network flexibility. Radio-overFibre techniqu...
