1)Describe the layout of fibre optic data transfer system.2)Detail the advantages/disadvantages and handling precautions for a typicalaircraft fibre optic system.3)Explain the basic operation of an optical data bus.1) Fiber-optic correspondence is a strategy for transmitting data starting with one place then onto the next by sending beats of light through an optical. The light structures an electromagnetic bearer wave that is regulated to convey data its focal points over electrical transmission, optical filaments have generally supplanted copper wire interchanges in center systems in the created world. Optical fiber is utilized by numerous media communications organizations to transmit phone signals, Internet correspondence, and digital TV signals. The waytoward conveying utilizing fiber-optics includes the accompanying essential strides: Creating the optical flag including the utilization of a transmitter handing-off the flag along the fiber, guaranteeing that the flag does not turn out to be excessively twisted or feeble, getting the optical flag, and changing over it into anelectrical flag. Optical fiber comprises of a center and a cladding layer, chose for aggregate inner reflection because of the distinction in the refractive record between the two. In reasonable strands, the cladding is typically covered with a layer of acrylate polymer or polyimide. This covering shields the fiber from harm yet does not add to its optical waveguide properties. Individual covered filaments (or strands framed into strips or packages) then have an intense pitch cushion layer as well as center tube(s) expelled around them to shape the link center. A few layers of defensive sheathing are added to frame the link. Unbending fiber gatherings some of the time put light-engrossing dull glass between the strands, to avoid light that holes out of one fiber from entering another. This lessens cross-talk between the strands, or diminishes flare in fiber package imaging applications.2)Advantages of using fiber optics are:•Lower attenuation. A 1550 nm, attenuation = 0.2 dB/km.•High power transmission: up to 32 Thz•km.•Immunity to electromagnetic interference.•Increased security. Fiber Optics is more difficult to puncture and no radiation signals are transmitted externally.•Extremely high bandwidth: This means that fibre optic is best for the transmitting data and no other cable offers the bandwidth like fibre optic cable.
•Early detection of cable damage: When fibre optic is damaged is decreases the speed of data transmission which indicates that we have to change the cable, splices in the cable can be detected as well. •Resistance to electromagnetic interference: Fibre optics has less error andit is noise free.•Smaller size and weight with greater flexibility compared to coaxical cables. The fiber cable weighs 10% to 30% less than copper.•High reliability and long operating life.
