Fibre Optic Research Paper

Fibre optic cables have gradually taken over as the transmission medium in local area networks as public telephone and data networks. Compared with electrically conductive cables are fibre-optic cables superior properties with respect to the range and bandwidth. The base material is glass and in some cable types of plastic. The cables therefore contain no metal and uses light transmission. Light waves have much greater bandwidth than electrical waves when the light wavelength is very short and the frequency correspondingly high. Fibre-optic cables can therefore transmit with much higher data rate, with tens of gigabits per second. Compared to twisted pair cables and coaxial cables are the benefits many. Advantages of fibre-optic: • Very high bandwidth and binary speed • Does not conduct electricity • …show more content…

It is a measure of how much the speed is reduced through the material relative to the vacuum. Wave lengths Wave lengths is the distance between two waves in a given period. Simply explained, its the length of the straight line between the two wave crest, but the wavelength can easily be measured at any other point of a wave. Precaution steps by working with fibre-optic cables and systems Laser light are used in fibre-optic cables. Laser light is divided into different categories according to their degree of dangerousness. The laser who are used in fibre-optic cables can be harmful to eyes and skin. • Never look into the end of a fibre. • Never look into laser diode or detectors or equipment for these components. The light is invisible, but will still be harmful. • Hold the fibre-optic cable well away form the eyes to prevent damage from the sharp fibre ends. • Protect yourself from injuries, like prick in the skin from fibre ends and fibre cuts. It can penetrate the skin and blood vessels without notice. • Fibre residues must always be in a suitable place in separate

    In half-duplex networks, the node transmitting must make sure that the network is quiet prior to transmitting, and in addition there is usually some mechanism for transmitting nodes to detect overlapping transmissions. 10BASE5 coaxial cable is the transmission technology used in the classic Ethernet protocol which was a stiff enough cable which was hard to install in buildings etc. as it was hard to bend. As it was hard to install along with other issues, 10BASE2 cable was made which was a skinnier coaxial cable which had obvious improvements in terms of installation.

    Answer1: When the transmission speed of ten megabits per second, the broadcast time of nine bits / 8x106 bits / second = 1 microsecond a large solitary byte. A good bit in connection with the 200 meters during optical fiber offers a large propagation time involving 200 meters / 2x108 meters / second = 1 microsecond. And so the area associated with 500 bytes requires 501 microseconds to arrive definitely with the recipient.

    The three most important properties of a wave are the wavelength, the amplitude, and the frequency. The wavelength is the distance from one point on a wave to the next identical point on the next wave. The amplitude is the distance from a waves rest position to either the crest or trough of the wave. The frequency is a rate which represents the amount of times a wave repeats

Nuclear medicine is a section of medical imaging that uses radioactive medication known as radiotracers or radiopharmaceutical (Understanding nuclear medicine, 2009). Radiotracers are given to the patient through injection, swallowing or inhalation, which makes the body radioactive for a short time. The radiation is detected by a special camera, and then the image is produced.

    There are different kinds of radiation such as ionizing radiation, like x-ray’s, and non-ionizing radiation, like ultraviolet rays. Welding lets off ultraviolet rays that can damage a welder’s eyes and burn his skin. To avoid the effects of radiation when welding, a welder should wear a suede jacket that protects his skin and wear a welding shield with a lens to protect his eye from the ultraviolet rays. Electrical hazards are another major concern in welding. The hazards of electrical injury are very severe and can be caused by cutting or welding.
