Both ends typically use MTP®/MPO or LC connectors, but compared with jumpers, trunk cables feature: Common designs include dual-jacket structures to enhance tensile strength and installation stability. They enable future-proofed optical network design and provide more efficient connectivity than multiple single cables that have separate connectors. Internally, the trunk utilizes a microcore cable construction, housing arrays of bare fiber (usually 250 µm) within an outer jacket fortified with aramid yarn for tensile. MPO (Multi-fiber Push On): MPO is a standard multi-fiber push-pull optical connector interface designed for high-density fiber connections. As an industry-standard interface specification, MPO defines the mechanical structure. This document outlines the main features and benefits of MPO trunk cable assemblies, including functional considerations, main technical parameters, operational aspects, and their service life in the context of the evolution of network structures.
