What is the most common type of fiber optic cable used for data transmission?

• A. Single-mode fiber
• B. Multimode fiber
• C. Coaxial cable
• D. Twist pair cable

Answer: (B)

The most common type of fiber optic cable used for data transmission is multimode fiber. This type of fiber optic cable is widely utilized in local area networks (LANs) and data centers due to its ability to support higher data rates over shorter distances. Multimode fiber has a larger core diameter than single-mode fiber, allowing multiple light modes to propagate simultaneously. This feature enables it to handle multiple data streams and can be more cost-effective for short-distance applications where high bandwidth is required. In environments like campuses and office buildings, multimode fiber is preferred because it generally has a lower installation cost and is easier to work with compared to single-mode fiber, which is designed for long-distance transmission and requires more precise alignment of optical components. Multimode fiber is well-suited for applications like video conferencing, data storage, and internet connectivity in scenarios where the cable runs are typically within a few hundred meters.
