Siemon Network Cabling Standards Guide

Dear customers, partners and friends,

At Siemon, we believe industry standards help you achieve the most out of your networks. For this reason, we have put together a guide to network cabling and data center standards.

We are pleased to introduce: Standards Informant.

Standards Informant is a new website covering a wide range of standards topics including twisted-pair cabling, fiber optic cabling, data center standards, pathways and spaces, bonding and grounding, industrial premises standards, building automation systems, energy efficiency and a whole lot more.

We hope you enjoy the new Standards Informant website.
