Develop the skills you need to design and build a reliable, cost-effective cabling infrastructure
Fully updated for the growing demand of fiber optics for large-scale communications networks and telecommunication standards, this new edition is organized into two parts. Part I covers LAN Networks and Cabling Systems offers comprehensive coverage on current cabling methodologies and is updated to the latest industry standards. Part II addresses Fiber-Optic Cabling and Components probes deeper into fiber optics, and can be used to prepare for the Fiber Optics Installer (FOI) and/or Fiber Optics Technician (FOT) certifications, two of the Electronic Technician's Association's leading certifications.
- Explains why cutting corners is a bad idea
- Walks you through the obstacles to high-speed data transfer
- Encourages you to follow the golden rules of cabling
This new edition is the only book you need for current cabling methodologies and standards.

original signal is received (in other words, the lower the better). Figure 1.14 illustrates the problem that attenuation causes in LAN cabling. Figure 1.14 UTP cable The signal deteriorates as it travels between a node on a LAN and the hub. PC Transmitted signal Hub Signal is weaker on the receiving side due to attenuation. Attenuation on a cable will increase as the frequency used increases. A 100-meter cable may have a measured attenuation of less than 2dB at 1MHz but greater than 20dB
problem, try extending problematic cable runs with extra-long patch cords. Recognized Media ANSI/TIA-568-C recognizes two types of media (cables) that can be used as horizontal cabling. More than one media type may be run to a single work-area telecommunications outlet; for example, a UTP cable can be used for voice, and a fiber-optic cable can be used for data. The maximum distance for horizontal cable from the telecommunications room to the telecommunications outlet is 90 meters (295´)
to use Category 5e cabling at minimum. The Bottom Line Identify important network topologies for commercial buildings. Over the years, various network topologies have been created: bus, ring, and star. From the perspective of cabling, the hierarchical star topology is now almost universal. It is also the easiest to cable. The ANSI/TIA-568-C and ISO/IEC 11801 Ed. 2 standards assume that the network architecture uses a hierarchical star topology as its physical configuration. This is the
