Description

Computer cabling is a crucial item in the company, due to its cost and its amortization over more than 10 years. This course revisits copper and optical techniques with illustrations by typical CCTP analysis. Promising new optical technologies and the place of carrier currents will be discussed.

Who is this training for ?

For whom ?

Technicians and engineers involved in the design and implementation of computer cabling, but also in charge of physical network infrastructure projects.

Prerequisites

Basic knowledge desirable in computer cabling techniques.

Training objectives

Assimilate the copper and optical infrastructures of computer cabling

Know the TIA, ISO and IEEE standards for cabling components

Test cabling using a cabling circuit scanner

Be able to analyze a CCTP (cabling specifications)

Training program

• Developments in copper and optical networks
  • Panorama of the evolution of techniques and performances over a quarter of a century.
  • Description of the different transmission media currently available.
  • Twisted copper pairs, fibers classic optics and recent developments.
• Network characterization and architecture
  • Twisted pairs: characterization and classification: categories 5, 5E, 6, 6A, 7, 7A, 8.
  • U/UTP, F/FTP, SF/FTP cables ... Certifications de-embedded (cat5E,6), re-embedded (6A).
  • Evolution of twisted pair tests: NEXT, attenuation, delay skew, return loss…
  • Silica optical fibers: multimode and single mode (OM1, OM2, OM3, OM4. OS1. OS2).
  • VCSEL injectors for multimode fibers. Recent contributions from active optical cables, MPO/MTP cassettes.
  • The change brought by OFDM in high speeds in difficult environments (Wi-Fi, 4G, CPL, ADSL, terrestrial TNT, etc.).
• Standards and performances
  • TIA/EIA, ISO/IEC standards for all computer cabling components.
  • Next evolution to 40 Gbit (40Gbase-T) of twisted pair Ethernet.
  • New advances in optical technologies.
• Indoor and outdoor, local, campus and metropolitan deployments
  • Optical fibers indoors and outdoors (Campus networks, operator networks).
• New networks
  • Carrier currents (IEEE P1901). Complement to copper and optical LANs.
  • Privileged targets: hotels, conferences, hospitals, museums, (surveillance camera, music and remote screens).
  • New types of fibers: FMF (restricted modes), MCF (multi-core) to increase single-mode throughput.
  • For new applications: HCF fibers (cores) hollow), microstructured fibers, bandgap fibers.
