Which of the following fiber-optic cable types can help data travel approximately 500 meters?
The different types of fiber-optic cables have varying capabilities in terms of data transmission distance
The different types of fiber-optic cables have varying capabilities in terms of data transmission distance. For a distance of approximately 500 meters, the two commonly used types of fiber-optic cables are Single Mode Fiber (SMF) and Multimode Fiber (MMF) cables.
1. Single Mode Fiber (SMF): SMF has a smaller core diameter, typically around 9 microns. It allows for a single mode of light propagation, enabling long-distance data transmission. The small core restricts spreading and bouncing of light waves, resulting in less signal loss over longer distances. SMF can transmit data over distances exceeding 10 kilometers. However, it’s worth noting that using SMF for shorter distances may be more expensive compared to MMF.
2. Multimode Fiber (MMF): MMF has a larger core diameter, typically around 50 or 62.5 microns. It allows for multiple modes of light propagation, which means light waves can follow different paths within the fiber. This results in higher dispersion and greater signal loss over longer distances compared to SMF. MMF is suitable for shorter-distance data transmission, typically up to a few hundred meters. It is commonly used for local area networks (LANs) or within buildings.
Considering that your requirement is for a transmission distance of approximately 500 meters, both SMF and MMF can be used. However, if you anticipate future needs of longer transmission distances or desire better performance, SMF would be most suitable.
