LAN Standards, News & Trends Report

Alfred Flores

Berk-Tek January 2013

Objectives

• Overview of Standards – Fiber Focus

• Recent events and activities of TIA TR-42 Subcommittees – Most recent meetings held in early October 2012

• Review the recent events and activities of some LAN application

subcommittees

Standards Overview

• What is the process for developing a standard? – Projects are proposed and must be approved – Contributions are reviewed – Draft documents are created then balloted to remove or

resolve contentious issues – With consensus, the document is released for publication – Can take a few months or many years

Standards Overview

• What is the process for revising a standard? – Maximum 5-year lifespan for standards

• Must be revised, re-affirmed or withdrawn – Addenda may be added to keep the document growing

with advances in technology • Addenda may then be incorporated into the new

revision of the standard.
