“…Variations in this process influence the phase delay function of the FBGs. Small differences in the phase delay function of the FBGs lead to variations in the drop penalty of FBGs [10]. These small differences in the drop penalties of the FBGs are assumed to be the explanation of the observed different system penalties at low BER in the metropolitan area network.…”

In this paper we present the topology of an optically transparent DWDM network testbed (part of the KomNet fieldtrial). We show results of our investigation on performance monitoring in the optical layer of this complex network. The testbed consists of a remotely configurable DWDM metropolitan area ring network (capable of transport up to 80x10 Gb/s) with two OADMs and one HUB/OXC and a long-haul bi-directional DWDM link (16x10 Gb/s, 8 spans over 750 km).

Phase distortions due to optical components play an important role in high speed optical transmission systems. Measurement methods for the phase transfer function of components are compared. As typical examples the phase distortions of two arrayed waveguide grating demultiplexers, a fiber Bragg grating add/drop filter and a dispersion compensating fiber Bragg grating are presented. Their resulting system impact is evaluated by means of experiments, simulations and an analytical model. Übersicht Phasenverzerrungen durch optische Komponenten spielen in hochratigen optischen Übertragungssystemen eine immer größere Rolle. Es werden Meßverfahren zur Bestimmung des Phasengangs optischer Komponenten miteinander verglichen. Als typische Beispiele werden Phasenverzerrungen von zwei AWG-Demultiplexem. eines Fasergitters als Bandpaßfilter und eines dispersionskompensierenden Fasergitters vorgestellt und die daraus resultierenden Signalverzerrungen durch Experimente, Simulationen und ein analytisches Modell behandelt.

“…It has excellent wavelength selectivity in its spectral characteristics. In telecommunication systems, fibre gratings have found a wide range of important applications such as dispersion compensation [2], optical filtering, optical add-drop multiplexing in optical Dense Wavelength Division Multiplexing (DWDM) systems [3,4], frequency stabilization of optical fibre lasers or semiconductor diode lasers [5], and gain flattening of erbium-doped fibre amplifiers [6], etc. They are also increasingly popular in various sensors for measuring temperature [7], pressure and strain [8], hydro-sound [9] and industrial process {1O].…”

Photosensitive optical fibres provide great potential for development of many important devices. The application of photosensitivity of optical fibres has profound impact to telecommunication at the 1550nm window and. increasingly, to optical fibre sensing as well as other systems. Large tunability in fibre grating is of great significance for future dense wavelength division multiplexing where channel selectivity and reconfigurability are of prime concern. The group in University of New South Wales has recently investigated the photosensitivities of various polymer optical fibres and has demonstrated that polymer optical fibre Bragg grating based on poly(methyl methacrylate) could be made and tuned over a range of more than 7Onm, far exceeding that could possibly achieved in conventional silica fibre Bragg gratings. More recently, the photosensitivity of a low loss new polymer fibre material-CYTOP has been demonstrated. These research activities and results unfold the great potential of realising a new class of fibre Bragg grating for various photonic applications. This paper will review the recent developments and will discuss some of the important prospects and remaining challenges in polymer fibre Bragg gratings and related topics.
