Solution:

Bandwidth x Length $=15 \mathrm{Mb} / \mathrm{sec} \times 4 \mathrm{~km}=(60 \mathrm{Mb} / \mathrm{sec}) \mathrm{km}$

Selecting optical source: LED at $820 \mathrm{~nm}$ is suitable for short distances. The LED generates $10 \mathrm{dBm}$ optical powers.

Selection of optical fiber: Step-index multimode fiber is selected. The fiber has bandwidth length product of …
