What is the definition of OSNR?

  1. The OSNR is defined as the ratio between the transmitted optical power and the received optical power over 1 km of fiber, including both signal and optical noise.
  2. The OSNR is the ratio between the optical output signal power and the optical input signal power of the device being analyzed.
  3. The OSNR is defined as the ratio between the average optical signal power and the average optical noise power over a specific spectral bandwidth.
  4. The OSNR is defined as the ratio between the optical signal power (including noise) and the optical noise power over a specific spectral bandwidth.

Answer(s): C



Which of the following are the main reasons for fiber attenuation?

  1. Refraction and reflection
  2. Scattering and absorption
  3. Chromatic dispersion (CD) and polarization mode dispersion (PMD)
  4. Small channel spacing

Answer(s): B



What is the meaning of first, second, and third window in the optical fiber propagation context?

  1. These windows correspond to three different minimum and maximum optical power levels used for optical transmission.
  2. These windows are three different wavelength intervals where the WDM optical transmission occurs.
  3. These three windows are three different angles of incidence of the light injected by the laser into the fiber.
  4. Different optical transmission windows correspond to different safety requirements and rules for the related lasers operating with these windows.

Answer(s): B



In which window(s) does the attenuation reach its minimum peak?

  1. First window (850 nm)
  2. Second window (1300 nm)
  3. Third window (1550 nm)
  4. Both first and second windows

Answer(s): C

Very up to date. I passed my exams. I studied very well though. But the past questions was exceedingly helpful too. Just practice the questions as much as you can. As for me I practiced all, and repracticed about 350 questions again before the exams day.
