DSP-4000 Series 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 Hz 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 142: Coaxial Cable
DSP-4000 Series 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 143: Basic Link Connections
Basic Cabling Testing Basic Link Connections Basic Link Connections The cable links you test may or may not include equipment patch cables and extra transition connections in the telecommunications closet and work area. For example, cable installers are often responsible only for the permanent cabling installed between the closet and the first wall outlet in the work area.
Page 144: Channel Connections
DSP-4000 Series Users Manual Channel Connections A channel includes the transition connectors and equipment patch cables added to a basic link segment. The channel should be tested from end to end to verify the performance of all the components. In this case, you use the equipment patch cables to connect your test tool to the channel, as shown in Figure 7-5.
Page 145: Permanent Link Connections
Basic Cabling Testing Permanent Link Connections Permanent Link Connections Permanent link test connections are similar to basic link connections, except that the effects of the test equipment’s patch cables are excluded from the test results. When compared to the basic link and channel, this test configuration provides the most accurate characterization of the permanently installed section of the cabling.
Page 146: Attenuation (Insertion Loss)
DSP-4000 Series Users Manual Attenuation (Insertion Loss) Attenuation is a decrease in signal strength over the length of a cable, as shown in Figure 7-7. Cable Signal Signal Receiver Source Loss oy30f.eps Figure 7-7. 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 147: Noise
Basic Cabling Testing Noise Noise Electrical noise is unwanted electrical signals that alter the shape of the signals transmitted on a LAN cabling. Figure 7-8 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 148: Characteristic Impedance
DSP-4000 Series Users Manual 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 149: Minimizing Impedance Discontinuities
Basic Cabling Testing Minimizing Impedance Discontinuities Minimizing Impedance Discontinuities Characteristic impedance is usually altered slightly by cable connections and terminations. Sharp bends 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.
Page 150: Next
DSP-4000 Series Users Manual NEXT The test tool measures NEXT (near-end crosstalk) by applying a test signal to one cable pair and measuring the amplitude of the crosstalk signals received by the other cable pairs. The NEXT value, expressed in decibels, is computed as the difference in amplitude between the test signal and the crosstalk signal measured at the same end of the cabling.
Page 151 Basic Cabling Testing FEXT and ELFEXT In cable, the inductive crosstalk component is very low. Most of the crosstalk is due to the capacitive component. Because the difference between the two components is nearly equal to the capacitive component, NEXT and FEXT are nearly the same in a cable.
Page 152: Locating Next And Elfext Problems
DSP-4000 Series Users Manual Locating NEXT and ELFEXT Problems If the test tool reports a NEXT or ELFEXT failure on a cable pair, you can use the HDTDX analyzer to locate the source of the crosstalk problem. Like the HDTDR results, the HDTDX analyzer results are presented in both a list and a plot format.
Page 153 Basic Cabling Testing Locating NEXT and ELFEXT Problems The vertical scale represents the magnitude of the crosstalk detected. The crosstalk levels shown on the plot are adjusted to compensate for cable attenuation. Without this adjustment, the peak on the right side of the plot (farther from the test tool) would appear much smaller.
Page 154: Split Pairs And Next
DSP-4000 Series 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 7-11 shows an example of split pair wiring.
Page 155: Minimizing Crosstalk
Basic Cabling Testing Power Sum Values 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 156: Propagation Delay And Delay Skew
DSP-4000 Series Users Manual Propagation Delay and Delay Skew Propagation delay is the time it takes an electrical signal to travel the length of a wire. A wire pair’s delay depends on the pair’s length, twist rate, and electrical properties, such as the type of insulating material used around the copper conductors.
Page 157: Nominal Velocity Of Propagation (Nvp)
Basic Cabling Testing Nominal Velocity of Propagation (NVP) 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.
Page 158: Nvp And Length Measurements
DSP-4000 Series Users Manual NVP and Length Measurements Length measurements depend directly on the NVP value entered for the selected cable type. To measure length, the test tool first measures the time it takes for a test pulse to travel the length of the cabling. The test tool then calculates cabling length by multiplying the travel time by the signal speed in the cable.
Page 159: Reflections From Opens
Basic Cabling Testing High-Definition Time Domain Reflectometry (HDTDR) Reflections from Opens An open, or break, in the cabling represents an abrupt increase in the cabling’s impedance. The impedance of an open is nearly infinite. In open cabling, a signal’s energy is not dissipated by a terminating impedance, so the signal bounces back towards the source.
Page 160: Reflections From Shorts
DSP-4000 Series Users Manual Reflections from Shorts A short represents an abrupt decrease in the impedance between 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 161: Cable Termination
Basic Cabling Testing High-Definition Time Domain Reflectometry (HDTDR) 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 162 DSP-4000 Series Users Manual 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.
Page 163 Basic Cabling Testing Figure 7-15 shows a plot of NEXT and attenuation limits, along with the resulting ACR plot. Notice that the ACR is lower where NEXT and attenuation values are near each other. 70.0 60.0 50.0 40.0 NEXT GOOD 30.0 GOOD 20.0...
Page 164 DSP-4000 Series Users Manual RL (return loss) is the difference between the power of a transmitted signal and the power of the signal reflections caused by variations in the cable’s impedance. A RL plot indicates how well a cable’s impedance matches its rated impedance over a range of frequencies.

Page 199 Appendix B Glossary 10BASE2 An IEEE Standard for Thin Coax Ethernet networks: 10 Mb/s transmission, baseband signaling, 185 meters per coax segment. Also known as Thinlan, Thinnet, or Cheapernet. 10BASE-T An IEEE Standard for unshielded twisted pair Ethernet networks: 10 Mb/s transmission, baseband signaling, unshielded twisted pair cable.
Page 200 DSP-4000 Series Users Manual Anomaly A location on network cabling where the cabling’s impedance changes abruptly. Attenuation (Insertion Loss) A reduction in the strength of a signal. Attenuation is usually expressed in decibels. Auto-Negotiation The ability of a network device to determine the capabilities of a far end device, then select settings for optimal communication.
Page 201 Glossary Baud Rate Baud Rate A measure of data transmission speed. Baud rate is the number of times per second that a signal changes states. If only one bit is encoded in each signal change, baud rate is the same as bits per second. If more than one bit is encoded in each change, the baud rate is lower than the bits per second rate.

Category 4 A cabling standard specified by EIA/TIA 568 for use at speeds up to 20 Mbps. Category 5 A cabling standard specified by EIA/TIA 568 for use at speeds up to 100 Mbps.
Page 203 Glossary Crossed Pair Crossed Pair A wiring error in twisted pair cabling where a pair on one end of the cable is wired to a different pair in the connector on the other end of the cable. Crosstalk Unwanted signal transfer between adjacent cable pairs. Crosstalk occurs because electrical signals passing through a cable pair create an electromagnetic field that transmits the signal to nearby pairs.
Page 204 DSP-4000 Series Users Manual Equal Level Far End Crosstalk (ELFEXT) The difference between the FEXT and the attenuation of the disturbed wire pair (in dB). Good cabling performance corresponds to high ELFEXT values, which result when FEXT is much higher than attenuation. Ethernet A local area network protocol using Carrier Sense Multiple Access with Collision Detection (CSMA/CD).
Page 205 Glossary HDTDX HDTDX  High-definition time domain crosstalk. The HDTDX analyzer locates sources of NEXT along cabling. This measurement technique is patented by Fluke Networks. Horizontal Cabling The cabling between a telecommunications outlet and a horizontal cross-connect. Horizontal Cross-Connect A group of connectors, such as a patch panel or punch-down block, that allows equipment to be cross-connected with patch cords or jumpers.
Page 206 DSP-4000 Series Users Manual Level I, Level II, Level IIE, and Level III Accuracy Levels of performance requirements for field testing of installed, unshielded twisted pair cable links. Level I is acceptable for testing channels. Level II has tighter limits and is preferred for testing basic links.
Page 207 Glossary Plenum Cable Plenum Cable Cable certified for installation in air ducts and open spaces over suspended ceilings without conduit. Plenum cable is fire resistant and does not emit toxic fumes when burned. Propagation Delay The time required for an electrical signal to travel the length of a cable. PSELFEXT Power sum ELFEXT.
Page 208 DSP-4000 Series Users Manual Runt Packet An Ethernet data packet that is shorter than the valid minimum packet length of 64 bytes. Runt packets are usually caused by a collision. Shielded Screened Twisted Pair (SsTP) Twisted pair cable in which each pair is wrapped in a metallic sheath, and the entire bundle is wrapped by an overall shield.
Page 209 Glossary Star Topology Star Topology A network design in which each node is connected to a central hub. Terminator A resistor connected to the end of a coaxial cable. The terminator, which is intended to match the characteristic impedance of the cable, eliminates signal reflections by dissipating signals in the cable.
