Optical Fiber Communications

Optical Fiber Communications. Week 4. Dispersion. Dispersion of the transmitted optical signal causes distortion for signal transmission along optical fibers. Dispersion mechanisms within the fiber cause broadening of the transmitted light pulses as they travel along the channel.
