Optical Communications
- WDM systems
- dispersion (material and waveguide) but not based on derivations of modes
- effects of dispersion on choices of fibre - DSF, DCF and NZ-DSF
- multimode fibres and capacity
- nonlinear limits on power transmission
- electronics dispersion compensation
- advanced coding formats applied to optical comms
- error budget and simple comparison to back-to-back BER / power
