SUMMARY
The discussion focuses on the performance of a Light Emitting Diode (LED) driving a 10 km single mode waveguide with a material dispersion of -100 ps/km/nm at a wavelength of 800 nm. The LED has a spectral width of 60 nm and is pulsed on and off in 5 ns. The optical pulse length at the end of the waveguide is determined by calculating the effects of dispersion and pulse duration. Additionally, the maximum practical pulse rate for distinguishable received pulses is analyzed based on the pulse length and dispersion characteristics.
