    PROLITE-50/51/52 is more helpful for field operation. It can help to check the qualification of optical fibre chain circuit on a regular basis. For the purpose of future maintenance, transmission quality and condition of optical fibre need to be recorded and stored, which includes measurement of optical path, total loss, and loss of all tie-ins and connectors.
  • Page 8 PROLITE-50/51/52 basic applications: • Measure the length of optical fibre and cable. • Measure the distance between two points on optical fibre and cable. • Locate faults and ruptures of optical fibre and cable. • Display distribution curve of optical fibre and cable loss.

    The magnitude of reflection depends on the difference between IOR and the smoothness of boundary. PROLITE-50/51/52 sends out a light pulse into connected optic fiber, and receive reflections of events and backward scattering power of pulse in time.
  • Page 13 Reflection Events When some pulse energy is scattered, reflection events happen. When reflection event occurs, peak shows on trace, as shown in figure 3. Figure 3.- Reflection Event. Non-reflection Events Non-reflection events happen at certain points where there is some optic loss but no light scattering.

  • Page 14: Measurement Application Of Prolite-50/51/52

    Inspection Event PROLITE-50/51/52 sends off a light pulse into the optic fiber to be inspected, and then receive returning light signals, and starts calculating the “event” distance. The farther the distance is, the longer time need for scattered light to be received by the instrument. Event distance can be calculated according to the time of receiving events signals.
