Which of the following fiber-optic cable types can travel approximately 100 km?
The most suitable fiber-optic cable type that can travel approximately 100 km is the single-mode fiber (SMF) cable
The most suitable fiber-optic cable type that can travel approximately 100 km is the single-mode fiber (SMF) cable.
Single-mode fiber cables have a smaller core diameter compared to multimode fiber cables, which allows for a stronger and more focused signal transmission. This type of fiber-optic cable is designed to carry only a single mode of light, reducing dispersion and allowing for longer transmission distances.
The core diameter of a single-mode fiber cable is around 9 μm, which is significantly smaller than the core diameter of multimode fiber cables (typically around 50 μm). Due to this smaller core size, single-mode fiber cables are capable of supporting long-distance transmission, making them ideal for applications that require communication over several kilometers.
In contrast, multimode fiber cables are better suited for shorter distance transmissions, typically up to a few kilometers. This is because the larger core diameter can cause more dispersion and loss of signal strength over longer distances.
Therefore, if you need to transmit data over a distance of approximately 100 km, the most appropriate choice would be a single-mode fiber-optic cable.
