Explanations of the TDR and TDX Basic troubleshooting procedures for LAN cable. LAN Cable Construction LAN cables have a number of characteristics in common with other types of electrical cables.
  • Page 114 Users Manual Cables are designed to perform best in specific applications. For example, power cables are designed to minimize power losses at frequencies of 50 or 60 Hz. LAN cables are designed to minimize signal distortion at higher frequencies. Two types of cables are designed for use with LAN systems: twisted pair cable and coaxial cable.

  • Page 116 Users Manual Coaxial Cable Coaxial cable consists of a conductor surrounded first by an insulating material, then by a braided conductive sheath, as shown in Figure 7-3. In LAN applications, the sheath is electrically grounded and serves as a shield that protects the inner conductor from electrical noise.

  • Page 117: Attenuation

    Basic Cable Testing Attenuation Attenuation Attenuation is a decrease in the strength of a signal over the length of a cable, as shown in Figure 7-4. Cable Signal Signal Receiver Source Loss gc30f.eps Figure 7-4. Attenuation of a Signal Attenuation is caused by a loss of electrical energy in the resistance of the cable wire and by leakage of energy through the cable’s insulating material.

  • Page 118: Noise

    Users Manual Noise Electrical noise is unwanted electrical signals that alter the shape of the signals transmitted on a LAN cable. Figure 7-5 shows an example of how noise affects the shape of an electrical signal known as a sine wave. Signals that are severely distorted by noise can cause communication errors in a LAN.

  • Page 119: Characteristic Impedance

    Basic Cable Testing Characteristic Impedance LAN cables act as antennas that can pick up noise from fluorescent lights, electric motors, electric heaters, photocopiers, refrigerators, elevators, and other electronic devices. Coaxial cable is far less susceptible to noise than twisted pair cable because it is shielded by a conductive sheath.
  • Page 120 Users Manual Minimizing Impedance Discontinuities Characteristic impedance is usually altered slightly by cable connections and terminations. Sharp bands or kinks in LAN cable can also alter the cable’s characteristic impedance. Networks can operate with small discontinuities because the resulting signal reflections are small and are attenuated in the cable. Larger impedance discontinuities can interfere with data transmission.

  • Page 121: Crosstalk And Near-End Crosstalk (Next)

    Crosstalk and Near-End Crosstalk (NEXT) Crosstalk is undesirable signal transmission from one cable pair to another nearby pair. Like electrical noise from outside sources, crosstalk can cause communication problems in networks. Of all the characteristics of LAN cable operation, crosstalk has the greatest effect on network performance. The test tool measures crosstalk by applying a test signal to one cable pair and measuring the amplitude of the crosstalk signals received by the other cable pairs.
  • Page 122 Users Manual The plot’s horizontal scale represents the distance along the cable under test. In the above example, the cursor is placed at a small crosstalk source caused by a connector 77 ft (23.5m) from the test tool. The vertical scale represents the magnitude of the crosstalk detected. The crosstalk levels shown on the plot are adjusted to compensate for cable attenuation.
  • Page 123 Basic Cable Testing Crosstalk and Near-End Crosstalk (NEXT) The scale of the vertical scale increases logarithmically. The scale units are arbitrary. A level of 50 represents a crosstalk magnitude that is close to causing a cable failure. The level of 100 is approximately 20 times greater than the level of 50.
  • Page 124 Users Manual Split Pairs and NEXT A split pair occurs when one wire from a cable pair is twisted together with a wire from a different cable pair. Split pairs most frequently result from miswires at punchdown blocks and cable connectors. Figure 7-7 shows an example of split pair wiring.
  • Page 125 Minimizing Crosstalk Crosstalk problems are minimized by twisting together the two wires in each cable pair. Twisting the two wires together causes the electromagnetic fields around the wires to cancel out, leaving virtually no external field to transmit signals to nearby cable pairs.

  • Page 126: Nominal Velocity Of Propagation (Nvp)

    Users Manual Nominal Velocity of Propagation (NVP) NVP is the speed of a signal through a cable relative to the speed of light. In a vacuum, electrical signals travel at the speed of light. In a cable, signals travel slower than the speed of light. Typically, the speed of an electrical signal in a cable is between 60% and 80% of the speed of light.

  • Page 127: Time Domain Reflectometry (Tdr)

    NVP Calibration The NVP values specified for standard cables are included in the cable specifications stored in the test tool. These values are accurate enough for most length measurements. However, the actual NVP for one cable type can vary up to 20% between batches because of variations in the manufacturing process.
  • Page 128 Users Manual Reflections from Opens An open, or break, in the cable represents an abrupt increase in the cable’s impedance. The impedance of an open is nearly infinite. In an open cable, a signal’s energy is not dissipated by a terminating impedance, so the signal bounces back towards the source.
  • Page 129 Reflections from Shorts A short represents an abrupt decrease in the impedance between the two conductors in a cable. A short is caused when the insulation surrounding a cable’s wires is damaged, allowing the wires to touch each other. The result is a near-zero impedance connection between the conductors.

  • Page 130: Cable Termination

    Users Manual Cable Termination Because signal reflections can distort the shape of communication signals, the unused ends of cable segments must be terminated to prevent reflections. The terminating device is a resistor with a value equal to the cable’s characteristic impedance.

  • Page 131: Acr

    Basic Cable Testing A negative reflection percentage indicates that the polarity of the reflection is the opposite of the original signal. Negative reflections are caused by abrupt decreases in the cable’s impedance, such as those caused by mismatches in cable types or shorts on the cable.
