A campus network is planning to install fiber-optic cables to replace outdated coaxial cables. They have the choice of installing single-mode, rnultimode, or a combination of single-multi mode fibers in the ground. Which fiber type should they select? Why?
a) Single-mode, because it allows for longer distances and higher bandwidth
b) Multimode, because it's cheaper and easier to install
c) Combination of single- and multimode, to cater to different needs
d) Multimode, because it's more resistant to signal loss over short distances
