This document describes the specifications for preparing, routing, and bundling cables and attaching labels to these cables. The optical cable and. A fiber trunk cable system, fully configurable to exactly suit your design. The design's goal is to maximize efficiency using loss budgets productively. Breakout design exists to. Fiber trunks are pre-terminated cable assemblies connecting switches, servers, patch panels, and zone distribution areas in the data center, or serving as the backbone of enterprise fiber networks. PreCONNECT STANDARD was the first high-fiber-count, and modular „plug & play“ fiber optic cabling system developed and manufactured. The development of high-density MPO fiber optic networks has led to the widespread use of fiber push cables.
