What is "Ethernet over Fiber"?

The concept of "Ethernet over Fiber" refers to a technology designed precisely for the purpose of transmitting Ethernet frames using fiber optic cables. This approach takes advantage of the benefits offered by fiber optics, including higher bandwidth, greater distances without signal degradation, and immunity to electromagnetic interference that can affect copper cables.

By utilizing fiber optics, Ethernet over Fiber enables organizations to deploy high-speed networking solutions that can handle vast amounts of data traffic, which is essential for modern applications and services that require reliable and fast connectivity. This technology serves as a backbone for many enterprise networks, supporting robust and scalable infrastructure.

Understanding the context of the other options clarifies this concept further: improving Ethernet speeds over copper cables pertains to methods that optimize existing infrastructure but do not capture the essence of fiber-based transmission. A protocol for managing fiber optic connections relates to how network devices communicate over fiber but does not describe the specific transmission of Ethernet frames. Lastly, a standard for wireless Ethernet communication is entirely distinct from fiber transmission, focusing instead on wireless technology and its respective protocols. Therefore, the correct description closely aligns with the nature and purpose of Ethernet over Fiber.
