32. A cable television service provider installs a physical medium that transmits broadband signals over long distances. Which type of cable is typically used in this situation?
Answer: A
Coaxial cables are typically used to transmit broadband signals over long distances.
Coaxial cables are designed specifically for transmitting cable television and broadband signals efficiently over considerable distances, making them the preferred choice for cable service providers.
A) Coaxial
Coaxial cables are constructed with a central conductor surrounded by insulation and an outer conductive shield, allowing them to carry high-frequency signals with minimal interference. This design is ideal for the transmission of broadband signals, making it the correct choice for cable television service providers.
B) Cat7
Cat7 cables are designed for high-speed data networking and are primarily used in local area networks (LANs). While they offer excellent performance for data transmission, they are not suitable for long-distance broadband signal transmission like coaxial cables.
C) Cat5e
Cat5e cables are also used for networking purposes and can handle data transmission up to a certain speed, but they are not designed for long-distance broadband signals. Their structure limits their effectiveness in comparison to coaxial cables for cable television services.
D) Twisted pair
Twisted pair cables, commonly used in telephone and data networking, can transmit signals over shorter distances but are not optimal for broadband signals over long distances. Coaxial cables outperform twisted pair cables in terms of bandwidth and signal integrity, particularly for cable television services.
Conclusion
Coaxial cables are the definitive choice for transmitting broadband signals over long distances due to their specialized construction that minimizes interference and supports high-frequency signals. All other options, while useful for specific applications, do not match the performance and suitability of coaxial cables in this context.
