Answer

Pulse dispersion primarily impacts the transmission time of information and bandwidth in a fiber optic system. Explanation 1. Identify the impact of pulse dispersion Pulse dispersion affects the transmission time of information by causing pulses to spread out over time, leading to overlapping signals and reduced clarity. 2. Analyze bandwidth implications Dispersion limits bandwidth because overlapping pulses reduce the ability to distinguish between different data bits, thus limiting the rate at which data can be accurately transmitted. 3. Evaluate receiver sensitivity Receiver sensitivity is affected as dispersion makes it harder for the receiver to detect distinct signal changes, potentially increasing error rates. 4. Consider insertion loss at the emitter Insertion loss is not directly impacted by dispersion; it relates more to signal attenuation rather than pulse spreading.
