Tray, ladder, trunking and conduit — standards-based cable pathways

Good cable on a bad pathway does not stay good. The pathway decides whether adding ten new ports five years from now is an afternoon of work or a separate project.

Choosing the pathway

Basket tray for main routes and suspended ceilings, ladder for heavy loads and runs between racks, trunking for surface routes in offices, conduit and duct for wall penetrations and protected routes, and floor systems for open-plan spaces.

Fill and growth

A tray is never filled to the rim. Fill is kept within the standard limit so that the cables underneath are not crushed and there is room left for future expansion.

Separating power and data

The data route keeps a defined separation from power lines, and at crossings the two run perpendicular to each other. In industrial environments that separation is greater and, where necessary, reinforced with a metal divider.

Frequently asked questions about cable pathways

Can network cable share a duct with power cable?

No. Sharing a pathway with power lines is not permitted by the standards, and in practice it causes noise and degrades link quality. The data route must be separate, and where a crossing is unavoidable it should cross the power route at right angles.
