Which statement about MPO trunks is true?

They are copper cables used for Ethernet. They carry multiple fibers arranged for MPO connector systems. They terminate with LC connectors. They are used for power distribution.

Correct Answer:

They carry multiple fibers arranged for MPO connector systems.

Explanation:

MPO trunks are fiber optic cables that bundle many fibers together in one cable and terminate in MPO/MTP interfaces. This setup is designed for parallel transmission and high-density interconnects in data centers. They are not copper cables or used for power distribution, and they don’t terminate with LC connectors—the LC family is a smaller, single-fiber connector typically used on individual fiber runs or breakout assemblies. The key point is that MPO trunks carry multiple fibers arranged for MPO connector systems, enabling multiple parallel channels in a compact footprint.
