What is the primary use of multimode fiber optic cable?

The primary use of multimode fiber optic cable is indeed high-speed applications over short distances. Multimode fiber has a larger core diameter, which allows multiple light modes to propagate through the cable simultaneously. This characteristic makes it well-suited for transferring data at high speeds, particularly within buildings or across campuses where distances are typically short, generally up to about 300 meters for standard applications.

Because of its design, multimode fiber is ideal for local area networks (LANs), data centers, and other networking environments where rapid data transmission is necessary but the distances involved do not exceed the capabilities of multimode. This allows for efficient network performance in applications such as video conferencing, high-definition video streaming, and other bandwidth-intensive tasks.

In contrast, other cable types or options would not be appropriate for the high-speed and short-distance applications that multimode fiber excels at. Long distance communication typically employs single-mode fiber due to its ability to transmit over greater distances with minimal signal loss. Other options, like low-voltage transmission and television broadcasting, do not pertain directly to the primary function of multimode fiber, as fiber optic cables are more commonly associated with data transmission rather than general power supply or standard broadcasting needs.
