  8. Which transmitters are suitable for sending pulses of light through optical fibres?

  9. Compare LEDs and ILDs.

  10. What is a photodiode used for?



XVII. Read the text again and decide whether these statements are true or false.


  1. Optical fibres are more expensive to install than copper cables.

  2. Optical fibres are not liable to interference.

  3. Copper cables cannot carry so much information as optical fibres.

  4. Injection laser diode is not compatible with optical fibres.

  5. Photodiodes are used at the beginning of the fibre.


XVIII. Combine words from Box A with words from Box B to make collocations.


A

cross

low

glass

plastic

armoured

infrared

B

cladding

cable

loss

talk

wavelengths

coating




XIX. Connect the words with their definitions.


    1. cross-talk f) reflection

    2. eavesdropper g) dispersion

    3. attenuation h) photodiode

    4. refractive index i) infrared

    5. cladding j) core


1. The part of the electromagnetic spectrum with a longer wavelength than light but a shorter wavelength than radio waves;

  1. The act or an instance of interfering;

  2. The loss of energy suffered by radiation as it passes through matter, especially as result of absorption or scattering;

  3. The process of protecting one metal by bonding a second metal to its surface;

  4. A light-sensitive diode that has twp terminals, an anode and a cathode, and that responds rapidly to changes of light;

  5. The separation of electromagnetic radiation into constituents of different wavelengths;

  6. A measure of the extent to which radiation is refracted on passing through the interface between two media;

  7. A process in which light, electromagnetic radiation, sound, particles, etc. are thrown back after impinging on a surface;

  8. A piece of magnetic material, such as soft iron, placed inside the windings of an electromagnet or transformer to intensify and direct the magnetic field;

  9. People who listen secretly to what other people are saying.


XX. Translate the sentences paying attention to the Subjunctive Mood.


1. It is necessary that the cladding and core should be covered with plastic coating to prevent dust from reaching the glass core. 2. Its high time you read about basic optics. 3. It seems as if refractive indices were different. 4. In order that greater bandwidth might be available light waves must have frequencies about 10000 times higher than the highest frequency radio waves. 5. There would be no fibre optics communication without two high technology inventions, the laser and low-loss fibre optics cable. 6. I wish you knew more about fibre optics communication. 7. It is important that glass should be pure, otherwise information could not travel through optical fibres for long distances. 8. Infrared LEDs are used with stepped-index multi-mode fibres so that they emit a wide beam of light with a large spectral bandwidth.


XXI. Practice the Conditional and the Subjunctive Mood while discussing the following ideas.


  1. What if the telephone had not been invented?

  2. What if printing had not been invented?

  3. What if everybody in the world spoke the same language?

  4. What if optical fibres had never been discovered?

  5. If you had only one day to live, what would you do?
