### AI overview

This article explains how "multi-core fiber" is used in data center discussions, distinguishing multi-fiber or high-fiber-count cables from true multicore fiber. It covers cable construction, fiber counts, single-mode and multimode options, and MPO and MTP connectors.

### Source excerpt

If you work around data centers and high-density builds, you have probably heard the term "Multi-Core Fiber" thrown around. People use it in a few different ways. Sometimes, it means a new fiber trunk that comes into a cabinet as a single cable and breaks out into dozens or even hundreds of fibers. That setup ...
