Advanced Polarisation Mode Dispersion and Chromatic Dispersion Testing
Verified
Key Learning Objectives:
- Understand the impact of signal dispersion on a digital communications system 1.
- Describe the relationship between the signal bit rate to the time duration of each bit in the signal 1.
- Explain how the spreading of a series of digital pulses can degrade the quality of the digital signal at the receiver 1.
- Apply a dispersion limit (e.g. ITU 10% limit) to a digital signal to determine the maximum permitted pulse spread2.
- Understand the concept of light as an electromagnetic wave and the effects of the refractive index 2.
- Identify the wave length for a sinusoidal wave 2.
- Describe how the refractive index of a material relates to the speed of a light wave3.
- Understand the concept of chromatic dispersion 3.
- Describe the concept of chromatic dispersion in optical fibres 3.
- Explain the concept of the ‘wave group’ 3.
- Explain how the optical fibre dispersion value is related to the group delay curve 3.
- Describe how the dispersion of standard optical fibre varies with wavelength 3.
- Identify the wavelength of minimum dispersion in a dispersion curve 3.
- Demonstrate the use the chromatic dispersion value of an optical fibre to calculate the amount of pulse spreading 3.
- Describe the basic principle of chromatic dispersion compensation4.
- Understand the principles of chromatic dispersion testing 4.
- Identify why it might be necessary to measure the chromatic dispersion of an optical fibre link 4.
- Describe one method for measuring Chromatic Dispersion in the field 4.
- Describe the concept of curve fitting with regard to Chromatic Dispersion measurement 4.
