OPTICAL RECEIVER

123456789101112131415
Across
  1. 1. sensitivity /minimum average optical power level at the photo detector
  2. 3. /height of the eye opening
  3. 8. / the chance that bit is corrupted and received in error.
  4. 9. of pulses
  5. 11. optical network
  6. 13. penalty/various signal impairments can reduce the SNR
  7. 14. partition noise/intensity fluctuations in the longitudinal modes.
  8. 15. noise/due to speckle pattern.
Down
  1. 2. fidelity determination.
  2. 4. line broadening when injection current of laser is directly modulated.
  3. 5. end amplifier/ boost the signal
  4. 6. pass filter/reduce the noise
  5. 7. of optical power level for logic 1 to the power logic for logic 0.
  6. 10. Noise due to thermal interaction between electrons and the vibrating ions.
  7. 12. noise/Deviation of the actual no. of electrons from the average numbers.
