O que é Cabeamento Estruturado - Introdução

Introduction to Structured Cabling

In this section, the speaker introduces the topic of structured cabling and outlines the purpose of the upcoming video series on this subject.

What is Structured Cabling?

• Structured cabling will be covered in the network videos.

• The first video serves as an introductory explanation of structured cabling.

• It involves components that follow national standards voluntarily adopted by companies.

Importance of Structured Cabling

• Structured cabling encompasses physical components for data communication architecture.

• Compliance with standards ensures organized infrastructure for telecommunications and data networks.

• Contrasted with unstructured cabling, which lacks standardization and hampers maintenance and troubleshooting efforts.

Benefits of Structured Cabling

This part delves into the advantages of structured cabling beyond aesthetics, emphasizing its impact on network performance and maintenance efficiency.

Advantages of Structured Cabling

• Structured cabling enhances network performance predictability and reliability.

• Facilitates quick layout changes and device additions or removals.

• Enables redundant data paths for continuous network operation in case of failures.

Implementation and Applications

Here, the discussion shifts towards implementing structured cabling across various network sizes and applications, highlighting its versatility and compatibility benefits.

Implementation Flexibility

• Structured cabling suits networks ranging from small to large scales seamlessly.

• Compatibility among equipment from different manufacturers ensures smooth operations.

Interconnection and Cabling Standards

The speaker discusses the interconnection process, emphasizing the use of intermediary equipment for linking elements and the importance of following specific pinout standards for network cabling.

Interconnection Process

• Interconnection involves linking elements using intermediary equipment to establish direct connections.

• Historical overview: Initially, network systems were closed, lacking interoperability. Standards like TIA/EIA 568 were developed to ensure structured cabling and interoperability.

• Evolution of cabling standards: TIA-568-B updated in 2001 dictates cable pinout order for RJ-45 connectors, with subsequent revisions (B1, B2, B3).

Cabling Standards

• TIA-568 series: Includes standards for cable pinouts; widely used in networking.

• Brazilian standards: ABNT norms like NBR 14565 provide guidelines for structured cabling; adherence is recommended but some companies prefer TIA/EIA 568 series.

Structured Cabling Components

The discussion focuses on the structure of structured cabling systems, highlighting six subsystems that compose a complete cabling system.

Structured Cabling System

• Structured cabling is divided into six subsystems that form a complete system.

• Subsystems include entrance facilities, equipment rooms, vertical and horizontal cabling, telecommunications rooms, and work areas where end devices connect.

Interconnection Illustration and Functions

The speaker illustrates how different components within a structured cabling system are interconnected to facilitate communication across various areas.

Interconnection Illustration

• External network connection enters through entrance facilities leading to equipment rooms housing servers and networking devices.

• Vertical backbone cabling connects telecommunications rooms across multiple floors or areas within a building.

Communication Flow

• Horizontal cabling links telecommunications rooms to work areas where end-user devices like computers or phones are connected.

Facilities and Equipment Rooms

Details about entrance facilities and equipment rooms within a structured cabling setup are provided.

Entrance Facilities

• Entrance facilities house incoming utility cables from external providers (e.g., telephone lines), including protective equipment against electrical surges.

Equipment Rooms

Telecommunications Infrastructure Overview

In this section, the speaker provides an overview of the telecommunications infrastructure, detailing components such as telecom rooms, horizontal cabling, fiber optics, work areas, and vertical cabling.

Telecommunications Rooms and Cabling

• Telecom rooms are simple closets in buildings where all telecommunication equipment is housed.

• The telecom room connects to horizontal cabling that carries network terminations to user stations like computers.

Work Areas and Vertical Cabling

• Work areas consist of connection points for devices like computers and phones.

• Vertical cabling involves cabinets on each floor connecting to the telecom room for distributing connectivity.

Elements of Structured Cabling System

This part delves into the various elements constituting a structured cabling system, including cables, patch panels, racks, connectors, and standards governing their usage.

Components of Structured Cabling System

• Elements include metallic and fiber optic cables, patch panels, conduits, racks for equipment storage.

• Different types of cables used are twisted pair copper cables (Cat5e/6), fiber optics with specific standards regulating their deployment.

Standardization in Telecommunications

The discussion focuses on standardization bodies like ISO and local organizations setting norms for structured cabling systems to ensure uniformity and efficiency.

Standardization Bodies

• International bodies such as ISO establish standards for transmission methods and installation techniques.

• Local organizations like ABNT in Brazil develop norms (NBR) aligning with international standards for structured cabling systems.

Importance of Knowledge in Networking

Emphasizing the significance of networking knowledge in structured cabling work to comprehend protocols, transmission rates crucial for effective implementation.

Networking Proficiency

• Understanding network protocols, transmission rates is vital for working with structured cabling efficiently.

• Deep knowledge aids in grasping reasons behind using specific cable types over others based on design considerations.
