1 CCNA 1 v3.1 Module 4 Cable Testing

2 Purpose of This PowerPoint This PowerPoint primarily consists of the Target Indicators (TIs) of this module in CCNA version 3.1. It was created to give instructors a PowerPoint to take and modify as their own. This PowerPoint is: NOT a study guide for the module final assessment. NOT a study guide for the CCNA certification exam. Please report any mistakes you find in this PowerPoint by using the Academy Connection Help link.

3 To Locate Instructional Resource Materials on Academy Connection: Go to the Community FTP Center to locate materials created by the instructor community Go to the Tools section Go to the Alpha Preview section Go to the Community link under Resources See the resources available on the Class home page for classes you are offering Search Contact your parent academy!

4 Objectives

5 Waves

6 Sine Waves and Square Waves

7

8 Exponents and Logarithms

9 Decibels

10 Viewing Signals in Time and Frequency

11

12 Analog and Digital Signals in Time and Frequency

13 Fouries Synthesis

14 Noise in Time and Frequency Ampere's Law states that any electrical current is surrounded by a magnetic field.

15 Sources of Noise EMI [electromagnetic interference] Interference by electromagnetic signals that can cause reduced data integrity and increased error rates on transmission channels. RFI [radio frequency interference] The radio frequencies that create noise that interferes with information being transmitted across unshielded copper cabling. Nearby cables that carry data signals Laser noise at the transmitter or receiver of an optical signal

16 White Noise Noise that affects all transmission frequencies equally is called white noise

17 NarrowBand Noise Noise that only affects small ranges of frequencies is called narrowband interference.

18 Bandwidth Analog bandwidth typically refers to the frequency range of an analog electronic system. [Hz] Digital bandwidth measures how much information can flow from one place to another in a given amount of time. [bps - bit per second]

23 Attenuation and Insertion Loss on Copper Media

24 Sources of Noise on Copper Media

25 Types of Crosstalk Near-end crosstalk (NEXT)

26 Types of Crosstalk Far-end crosstalk (FEXT)

27 Types of Crosstalk Power sum near-end crosstalk (PSNEXT)

32 Time-based Parameters

33 Testing Optical Fiber

35 New Standard On June 20, 2002, the Category 6 (or Cat 6) addition to the TIA-568 standard was published. This new standard specifies the original set of performance parameters that need to be tested for Ethernet cabling as well as the passing scores for each of these tests. A quality cable tester is the Fluke DSP-LIA013 Channel/Traffic Adapter for Cat5e.
