Network IQ Training Manual Chapter 5 Structured Cabling

Network IQ Training Manual Chapter 5 - Structured Cabling Standards for Fibre Systems

Agenda • Purpose of Standards • Cabling Standards Worldwide • Key Standards for Structured Cabling • fibre Optic Classes • Duplex System Polarity • New Standards/Updates • Summary Optical Fibre Network IQ Training Manual 2

Purpose of Standards (Cabling and Communication Systems) • Promote trade and commerce • Set rules for an open system, open participation. • Ratification based on voting ballot process: – Voters consist of customers, consultants, manufacturers • Protect customers when buying from multiple manufacturers – Ensures compatibility of components between vendors • Provide guidance or recommendation for products to ensure consistent operation of a system Optical Fibre Network IQ Training Manual 3

Purpose of Standards (Cabling and Communication Systems) Cable Transmission Protocol • Different components and features of a system must be defined • Standards help solve the puzzle of compatibility problems Testing Connector Mating Fire Resistance • However understanding the Standards can also be a puzzle!

The Need for Structured Cabling Server Racks • • Point to point structure The cabling starts with a few connections… and this is how it ends up. . . - No defined cable paths - Changes made at active equipment - Problem determination difficult - System growth can be impacted - Mess under the floor Storage Switch Racks Optical Fibre Network IQ Training Manual 8

Summary Cabling Standards • Standards provide guidance for components and systems to ensure installed systems perform properly and reliably support various protocols. • Standards ensure products from different vendors are compatible. • EN 50173 (based on ISO/IEC 11801 ) is the European standard for structured cabling – Some customers may follow TIA 568 C in Europe, MEA region • 40 G and 100 G ratified June 2010 – Require MTP connectivity and OM 3 fibre (minimum) Optical Fibre Network IQ Training Manual 22
