Abstract
Deployment of new applications over local area network (LAN) cable technologies is moving forward at a lightning pace. With the emerging applications demand it has become very critical to select the right design of cable meeting current and upcoming applications needs. Structured cabling installations with lesser control and aggressive execution schedule, many times results in poorly installed systems. Structured cabling design planning includes pathways, containments and other necessary best practices which are very critical to achieve better headroom results in installed SCS (Structured Cabling System).
1. Introduction
Let’s understand dynamics around, project site field conditions, errors done during execution and how system integrations skill gap variability may impact installed cable performance. Considering field constraints and competitive market trend also changing .Now a day’s major quality OEM confirming guaranteed minimum 4- 6 dB headroom margin compliant to 90meter ANSI TIA-568- C.2 horizontal link performance .The same information getting incorporated in various large tender specifications ultimately eliminating many small players with limited capability to deliver such high performance margins absorbing certain level of field efficiency loss.
