Choosing the Right Fiber-Optic Cable for Your Campus Network | Multi-Mode vs. Single-Mode

Which of the following fiber-optic cable types is used within a campus network?

The type of fiber-optic cable used within a campus network is typically either multi-mode or single-mode fiber-optic cable

The type of fiber-optic cable used within a campus network is typically either multi-mode or single-mode fiber-optic cable.

1. Multi-mode Fiber-optic Cable (MMF):
– Multi-mode fiber-optic cable has a larger core diameter, usually 50 or 62.5 microns, along with a larger numerical aperture.
– It is capable of transmitting multiple modes or paths of light simultaneously.
– MMF is often used for short-distance applications within a campus network, such as connecting devices within a building or between nearby buildings.
– It is suitable for lower-bandwidth applications like local area networks (LANs) and can support data rates up to 10 Gbps.

2. Single-mode Fiber-optic Cable (SMF):
– Single-mode fiber-optic cable has a smaller core diameter, typically 9 microns, and a narrower numerical aperture.
– It allows only a single mode or path of light to propagate through the core, resulting in reduced dispersion and better signal quality.
– SMF is generally utilized for long-distance connections within a campus network, such as connecting buildings that are farther apart.
– It is suitable for high-bandwidth applications and can support data rates up to 100 Gbps or more.
– Single-mode fiber-optic cable is commonly used in wide area networks (WANs) and backbone connections.

In summary, both multi-mode and single-mode fiber-optic cables are utilized within a campus network. Multi-mode is suitable for short distances and lower bandwidths, while single-mode is ideal for longer distances and higher bandwidths. The choice of cable type depends on the specific requirements and budget of the network.
