Which type of media can ATM run over?

Asynchronous Transfer Mode (ATM) is a networking technology that supports the transmission of voice, video, and data. It is designed to work across multiple types of media, offering flexibility in how network infrastructure is implemented. The correct answer points out that ATM can operate over both twisted-pair cables and fiber optics.

Twisted-pair cables, commonly used in telephone and broadband networks, are capable of carrying ATM signals, particularly in local area networks (LANs). Fiber optics, on the other hand, provide a higher-bandwidth option for transmitting data over long distances with minimal signal loss, making them a strong fit for ATM applications as well.

This combination of media types allows ATM to be more versatile and adaptable in various network configurations, accommodating the differing requirements of voice, video, and data traffic efficiently. Consequently, both twisted-pair and fiber optics are supported by ATM, which is essential for diverse deployment scenarios in modern telecommunications.
