QUESTION 1 1.1 In any long-haul optical fibre communications channel, it is important to have a large Bandwidth-Length Product (Hz-km). Name 4 things that could be considered in order to increase the Bandwidth-Length Product of a specific length of optical fibre. (4) 1.2 An optical fibre has a core diameter of 9 um and a refractive index of 1.466. The cladding refractive index is 1.442. 1.2.1 Determine if the fibre will permit single mode transmission at a wavelength of 1320...

10. Write a one-page summary of the attached paper? INTRODUCTION Many problems can develop in activated sludge operation that adversely affect effluent quality with origins in the engineering, hydraulic and microbiological components of the process. The real "heart" of the activated sludge system is the development and maintenance of a mixed microbial culture (activated sludge) that treats wastewater and which can be managed. One definition of a wastewater treatment plant operator is a "bug farmer", one who controls the aeration...
