  15. Why is measuring Dispersion so important?

  16. Dispersion compensation

  17. Dispersion compensation for DWDM

  18. CD management Prevention: 1. Compensation: - Fibers DCF & RDF, - Bragg Gratings technique. 2. Decreasing impulse spectral width: - external modulation, - pulse shaping of current modulation. 3. Solitontransmission.
