Explanation:

Single-mode fiber is a type of optical fiber that has a small core diameter and allows only one mode of light to propagate. This reduces signal attenuation and increases transmission distance, making it suitable for long-distance communication networks. Single-mode fiber can carry data over thousands of kilometers without requiring repeaters or amplifiers. Single-mode fiber is also immune to electromagnetic interference and has a higher bandwidth than multimode fiber. Therefore, single-mode fiber is the best cable type for connecting sites on multiple continents. Reference: [CompTIA Network+ Certification Exam Objectives], [Single-mode optical fiber - Wikipedia]

Single-mode fiber optic cable uses a single ray of light to transmit data. This allows it to achieve very low attenuation and high bandwidth.

Multimode fiber optic cable uses multiple rays of light to transmit data. This results in higher attenuation and lower bandwidth than single-mode cable.

Twisted pair copper cable uses two insulated copper wires to transmit data. It is less expensive than fiber optic cable, but it has higher attenuation and lower bandwidth.

When choosing a cable type for a long-distance application, it is important to consider the following factors:

Attenuation: The amount of signal loss that occurs over the length of the cable.

Bandwidth: The amount of data that can be transmitted over the cable per second.

Cost: The cost of the cable and installation.

Single-mode fiber optic cable is the best choice for long-distance applications because it has the lowest attenuation and highest bandwidth of any cable type. However, it is also the most expensive cable type.
