An electron microscope uses a beam of highly energetic electrons to illuminate the object. As compared to the optical microscopes‚ electron ones can produce highly magnified images. Electrostatic and electromagnetic lenses are used in electron microscopes. These lenses control the electron stream and focus it to a specific plane of the sample. This method is similar to that of an optical microscope‚ which uses light to focus on the specimen. The original version of electron microscope‚ called transmission

Technology over the past century has advanced greatly. Fibre optics however is being utilized since more than a hundred years. Optical fibre is a model that has evolved greatly over time. From guided transmission lights experiments to lasers and light emitting diodes (LED)‚ and to dense wavelength-division multiplexing (DWDM)‚ the area under which optical fibre can be used has expanded. One of the modern and commonly used applications of fibre optics is high resolution visuals (HDTV) which

------------------------------------------------- ABSTRACT The race for unprecedented bandwidth is on - and DWDM(Dense Wave-length Division Multiplexing) is opening the way. DWDM is the technology that allows multiple streams of data to flow in one optical fiber of optical communication network. DWDM is the key technology at the heart of new systems and networks that offers more bandwidth at less cost. Soon‚ DWDM promises to change bandwidth from a premium to a commodity item.
