What is the cable type and maximum distance of 10GBASE-E?

The correct answer identifies the appropriate cable type and maximum distance for 10GBASE-E, which is designed specifically for long-distance single-mode fiber applications. 10GBASE-E utilizes single-mode fiber optic cables, allowing for greater transmission distances compared to multimode fibers.

In this case, the maximum distance of 30 kilometers is applicable to 10GBASE-E, making it suitable for interconnecting equipment across vast distances, such as in large enterprise networks or data centers. Single-mode fiber's low attenuation and higher bandwidth capability support the long distances required for this standard, which makes it a preferred choice for extensive deployments.

The other options focus on maximum distances and cable types that do not correspond accurately to the specifications of 10GBASE-E. Multimode fibers, while effective for shorter distances, have different limitations and are not designed for the same extended range as single-mode fibers, making them unsuitable for 10GBASE-E applications.
