Which fiber option should be chosen given the presence of legacy systems and a need to control costs?

• A. Single-Mode Fiber
• B. Multimode Fiber
• C. Hybrid Fiber
• D. Coaxial Cable

Answer: (B)

When you’re dealing with older equipment and a need to control costs, the choice that fits best is multimode fiber. It uses cheaper light sources and transceivers, which lowers both the initial deployment price and ongoing maintenance. It’s well suited for the shorter link distances typical inside buildings and campuses, so you can deploy quickly without the premium optics and long-haul capabilities that single-mode fiber demands. That makes it easier to reuse or upgrade existing legacy gear without a big upfront investment, helping you keep overall costs down. Single-mode fiber, while powerful for long distances and future growth, requires more expensive transceivers and more precise installation, which clashes with a tight budget and a need to work with legacy systems. Coaxial cable isn’t a fiber option at all, so it wouldn’t meet the fiber requirement. Hybrid fiber can sometimes be used, but it often adds complexity and procurement considerations without offering a clear cost or compatibility advantage for a scenario centered on legacy equipment and cost control.
