How to measure strain using fiber Bragg gratings
This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed. The work is devoted to the consideration of methods for determining the strain of objects using fiber Bragg gratings under a high-frequency vibration or pulsed mechanical action, which is difficult to perform using widespread methods and devices. A fiber Bragg grating is a small length of optical fiber that comprises a pattern of many reflection points that creates a reflection of particular wavelengths of incident light.

Methods for Detecting Stress in Fiber Bragg Gratings
This paper gives a short introduction to FBG sensors, points out their special strengths and weaknesses and describes a measuring system which enables strain gages and FBGS to be measured simultaneously, providing all data processing functions originally developed for the. Fiber Bragg Grating Sensors (FBGS) are gaining increasing attention in the field of experimental stress analysis. They are easy to install, immune to electromagnetic interferences and can also be used in highly explosive atmospheres.

Current Status of Fiber Optic Communication in Papua New Guinea
Papua New Guinea is enhancing its digital infrastructure through an extensive National Transmission Network. PNG DataCo, a subsidiary of Kumul Consolidated Holdings, operates the NTN, which spans over 12,000 km of fibre cable. As telecommunications connectivity reaches 80 per cent of Papua New Guinea's population, Business Advantage PNG looks at how the country's telecommunications wholesaler, PNG DataCo, is working to encourage greater adoption of the internet by business and consumers. Papua New Guinea's internet system continues to rely heavily on fibre optic cables, despite the growing presence of satellite-based services across the country, according to PNG DataCo. Work is underway to lay high speed telecommunication cables from Australia to Papua New Guinea and Solomon Islands, including a domestic network connecting Honiara with Auki, Taro and Noro. The Coral Sea Cable System (CS 2) will deliver faster, cheaper and more reliable communications. In addition, DataCo manages three tied data centers and 51 satellite infrastructures throughout Papua New Guinea (PNG).
