CHAPTER 1: Introduction

1. Introduction

1.1 The Digital Solution for Fiber and Copper

OMNIScanner is the most advanced hand-held certification and diagnostic tool for the verification of copper links. The Category 7, 6, 5E (Enhanced), 5 and ISO Class F, E, D, and C tester has an extended frequency range of 300 MHz. OMNIScanner provides full software compliance with TIA and ISO/IEC requirements for measurement reporting and analysis (including Length, Delay, ACR, NEXT, ELFEXT, Return Loss, Resistance, PSNEXT, PSACR, PSELFEXT, and Attenuation). In addition, OMNIScanner measures Length, Delay, Impedance, and Resistance on coaxial cabling.

OMNIFiber expands the tester’s capabilities to certify installed fiber links against TIA and ISO standards. Fiber cabling can be verified at 850 and 1300 nm wavelengths.

1.2 The Graphical User Interface

OMNIScanner’s graphical user interface consists of a backlit LCD display, quickaccess menus, arrow keys, and descriptive menu options that guide you through certifying or troubleshooting cabling systems.

1.3 OMNIRemote

For test and certification of twisted-pair cabling, the OMNIScanner requires the OMNIRemote unit at the opposite end of the cabling link under test. OMNIScanner communicates with OMNIRemote to obtain status and perform measurements from both ends of the link.

OMNIRemote is equipped with a speaker to generate tones, and several colored LEDs to indicate overall test results and status.

1.4 OMNIFiber

OMNIFiber transforms OMNIScanner and OMNIScanner2 into a fiber optic tool for testing and certification of multimode and single-mode fiber premise networks. OMNIFiber consists of two identical test heads that attach directly onto OMNIScanner and OMNIRemote to become a part of each unit. Using the 1Button Autotest feature, OMNIFiber measures loss (multimode and single-mode) and length (multimode) over two fibers simultaneously. The measurements are

OMNISCANNER

compared against the selected LAN standard for instant PASS/FAIL analysis. OMNIFiber measures loss at 850 and 1300 nm over multimode fiber and at 1310 nm over single-mode fiber.

Up to 1000 Autotests can be saved to nonvolatile memory. Saved results can be easily uploaded to the PC with Scanlink software.

1.5 Scanlink Tools Software

PC-based software expands OMNIScanner’s user interface and aids with the management of projects. Scanlink Tools consist of the OMNIScanner Configuration software, the Scanlink Upload software, and the OMNIScanner Remote Control software.

IREMAP

The Wiremap function tests twisted-pair cabling for proper wiring. Your cabling configuration is checked for shield continuity, opens, shorts, crossed pairs, split pairs, and reversed pairs. For each pair, Wiremap displays the length.

The screen displays a graphical representation of the wiring in your cable, where the near end wiring is shown on the left side, and the far end wiring on the right side of the screen.

10X

CHAPTER 5: Measurements

• A reversed number indicates a split pair.

• A straight line between pairs indicates a good pair.

• No line between wire pairs indicates an open.

• An X between wire pairs indicates a reversed pair.

• A | between wire pairs indicates a short.

• The measured length of the pairs 1-2, 3-6, 4-5, and 7-8 are shown on the left side.

In the example, OMNIScanner displays split pairs on 1 - 2 and 4 - 5 although they are wired straight through, a reversed pair 3 - 6, an open on wire 7, and a short on wire 8 to the Shield.

Press ESC to exit the WIREMAP screen.

5.3.2 L

ENGTH/DELAY

The Length/Delay function measures a cable’s length, propagation delay, and skew. OMNIScanner will determine whether the cable is open or shorted.

The accuracy of the NVP (Nominal Velocity of Propagation) setting determines the exactness of length measurements. The NVP specified by cable manufacturers is used for all the cables in OMNIScanner’s library. When creating or editing cables, the NVP value can be customized. (See Section 3.5, Setup: Cables, for further information.)

Delay is a measure of the time required for a signal to travel from one end of the circuit to the other. OMNIScanner measures the delay from when the pulse was sent and when the reflection was received. Knowing the speed that the pulse

OMNISCANNER

propagates down the cable (NVP), OMNIScanner then calculates the length of the cable.

Skew is the difference between the delay on the longest and shortest wirepairs.

The Length/Delay screen shows the test result information for all pairs.

The Limit is displayed at the top of the screen.

The pairs are displayed in the first column followed by small icons to indicate whether the pair is open or short.

The measured Length and the Delay are displayed for each pair. The result for the shortest pair is tagged with a PASS or FAIL indicator.

The length result can be displayed in meters or feet (see Chapter 4: Setup User Options).

Delay is displayed in nS (nanoseconds).

The Skew value and the Skew limit are displayed right below the pairs.

Press ESC to exit the LENGTH/DELAY screen.

5.3.3 NEXT

The NEXT (Near End Crosstalk) function measures the electromagnetic coupling that occurs between pairs at the near end. OMNIScanner and OMNIRemote allow NEXT to be measured at both ends of the link without having to swap ends.

OMNIRemote functions as a terminator while OMNIScanner transmits a signal which is monitored on the receive pair. The received signal is compared to the transmitted signal and the difference is reported as the NEXT value in dB. When

CHAPTER 5: Measurements

measuring the NEXT for the OMNIRemote end, the roles of the two units are reversed. OMNIScanner provides the termination; OMNIRemote transmits and receives the signal.

In the NEXT screen, the worst case margin for all near and far pair combinations is shown at the top of the screen.

Attenuation always reports the worst dB value regardless of the Report: setting in the RUN OPTIONS screen.

5.3.5 R

ETURNLOSS

The Return Loss function measures the uniformity of a cable’s impedance. OMNIScanner injects a signal into the cable and measures the reflected signal strength. Return Loss measures the difference between the transmitted signal delivered to the cable and the reflected signal at the input port of the cable. The reflected signal is the result of impedance mismatches in the link under test.

In the RETURN LOSS screen, the worst case margin for all near end and far pairs is shown at the top of the screen.

The pairs are displayed in the column on the left side, followed by the Return Loss in decibels (dB), the Return Loss margin/limit, and the frequency. The result for each pair is tagged with a PASS or FAIL indicator.

5.3.7 ACR/B

ANDWIDTH

Attenuation to Crosstalk Ratio (ACR) is an indication of how much larger the received signal is compared to the Near End Crosstalk (NEXT) on the same pair. ACR is calculated from the measured NEXT and Attenuation. The ACR value is computed at each measured Attenuation frequency. The worst-case ACR is reported for each pair combination.

OMNISCANNER

Bandwidth is a measure of the usable frequency range of the link under test. For most networks, this is the highest frequency at which the signal can easily be distinguished from background noise. Depending on the selected Autotest, the worst pair to pair ACR is typically 3 dB.

In the ACR screen, the Bandwidth is displayed at the top of the screen.

The pair combinations are located in the column on the left side, followed by the measured ACR, the ACR margin/limit, and the frequency. The result for each pair combination is tagged with a PASS or FAIL indicator.

5.3.8 R

ESISTANCE

Resistance is measured in a loop through each pair in the cable. In a twisted-pair cable, Resistance is measured by using OMNIRemote to short the far end of the pair under test.

The RESISTANCE screen displays the Resistance Limit and the test results in ohms for each pair. The result for each pair is tagged with a PASS or

FAIL indicator.

Press ESC to exit the RESISTANCE screen.

5.3.9 P

OWERSUM

Like NEXT, Power Sum NEXT is a measurement of electromagnetic coupling between adjacent pairs. While NEXT reports test results for each pair combination, Power Sum NEXT is calculated from NEXT for individual pair combinations and takes into account the crosstalk from multiple transmission pairs. When reporting Power Sum NEXT, OMNIScanner displays results for pairs, rather than pair combinations. The PS NEXT measurement is required to assure proper operation of networks employing simultaneous transmission on more than one pair in a link (Gigabit Ethernet, for example).

In the POWER SUM NEXT screen, the worst case margin for all near and far pairs is shown at the top of the screen.

OMNISCANNER

The pairs are displayed in the column on the left side, followed by the PS NEXT in decibels (dB), the margin/limit, and the frequency. The result for each pair is tagged with a PASS or FAIL indicator.

FFICELOCATOR

The Office Locator function allows you to find the termination of an office cable drop from a wiring closet. It eliminates the need to trace cables through walls and ceilings.

CHAPTER 5: Measurements

1. Connect the cable to be tested to OMNIScanner.

2. Insert the RJ-45 Office Locator adapters into wall outlets in the offices you wish to identify. You can connect any or all of the twelve Office Locators before beginning your test.

3. At the patch panel, run the Office Locator function to identify which office is connected to a given port.

OMNIScanner will identify office locations and display the ID of the Office Locator adapter found at the far end of the attached cable.

If you are testing a cable that does not have an Office Locator attached at the other end, OMNIScanner will display a question mark.

5.4 Fiber Optic Measurements with OMNIFiber

5.4.1 L

ENGTH/DELAY

The Length/Delay function measures a fiber’s length and propagation delay. Length measurements are derived from the propagation delay results using the GRI (Graded Refractive Index) at the appropriate wavelength.

Propagation Delay is the measure of the time required for a signal to advance from one end of the link to the other. When measuring propagation delay, OMNIScanner measures the round trip delay through both fibers, and then divides the result by two, assuming that the cables are equal in length.

Propagation Delay cannot be measured on a single-mode fiber; this measurement is available for multimode fiber only.

OMNIScanner measures the full length of the fibers under test.

CHAPTER 5: Measurements

The LENGTH/DELAY screen displays the GRI @ 1300 nm (nanometers).

The length limit and the actual derived length are displayed in meters or feet.

The delay is displayed in nanoseconds (nS).

Press ESC to exit the LENGTH/DELAY screen.

5.4.2 L

OSS

The Loss function measures the signal loss in a fiberoptic cable. The adapters inject a signal into the fiber cable and OMNIScanner and OMNIRemote measure the received signals at 850 and 1300 nm for multimode fiber cables and 1310 for single-mode fiber cables.

The LOSS screen displays the measured power in dBm (decibels, one milliwatt reference) for each wavelength.

The measured loss and limit values in decibel (dB) are displayed for both wavelengths.

OMNISCANNER

For dual fiber testing, the arrows at the top of the screen point out the direction of the light and indicate which fiber the result is for.

NOTE

When measuring single-mode fiber cables, OMNIScanner displays results for the wavelength; the upper (850 nm) section will be blank.

Press ESC to edit the LOSS screen.

5.4.3 P

OWERMETER

The Power Meter function reports the overall received power. Use it to quickly verify and correct cabling and equipment problems.

The Power Meter screen shows the currently selected wavelength and light source mode.

The overall power is displayed.

OMNIFiber is designed to provide a consistent, calibrated light source for effectively measuring signal loss in fiberoptic cables. The transmitted light can be operated continuously or modulated.

When testing loss, use the continuous light source. When identifying fiber cables with a tone locator, use the 2 kHz modulated mode.

Press (Continuous) or (Modulated) to change the light source.

Press or to change the wavelength of the OMNIFiber main transmitted and received wavelengths. Either main or remote can be used as the light source with the main power meter.

CHAPTER 5: Measurements

When OMNIFiber is attached to OMNIRemote, the remote unit can be used as a light source. With the OMNIFiber adapter attached, press the lambda key to activate the light source and provide continuous or modulated light at 850 or 1300/1310 nm. The green LED of the appropriate wavelength will blink rapidly when modulated light is transmitted. If the transmitted light is continuous, the green LED will not blink.

Press to find the reference value, place it in the appropriate field, and start calculating the loss.

Press ESC to exit the Power Meter screen.

5.5 Coaxial Measurements with OMNIScanner

OAXTESTS

In coaxial cable, an insulated wire runs through the middle of the cable and a second wire, called the shield, surrounds the insulation of the inner wire like a sheath. The outer insulation jacket wraps around the second wire.

The Coax Tests screen displays the measured Length, Impedance, and Termination.

The Length function measures the cable length. OMNIScanner will display the overall length in meters or feet. If NEF (No End Found) is displayed instead of a value, the cable is either too long or terminated in its characteristic impedance.

Impedance defines the relationship of voltage and current in an electrical circuit.

OMNISCANNER

Each Cable or transmission line is designed to have specific impedance, which allows proper matching to the currents of the transmitter and receiver. OMNIScanner measures the characteristic impedance of the coax cable in ohms.

The Termination function displays whether a cable is open or shorted

When the field Length displays NEF, the Termination will display .

6. Diagnostics

6.1 OMNIScanner’s Diagnostic Functions

OMNIScanner has several advanced diagnostic test functions to help you with the identification of network cabling faults. Diagnostics allows you to locate opens, breaks, and short circuits as well as NEXT and Return Loss cabling faults quickly and easily.

Press the (Diagnostics) function key to display the Diagnostics screen.

6.2 Wiremap

Wiremap identifies the location of opens, breaks, and pairs that are shorted. This allows quick identification of the fault location.

Select Wiremap to display the WIREMAP screen. The screen displays the wire connections between OMNIScanner and OMNIRemote. The pairs that are being tested are defined by the selected test standard. Shield continuity is tested if a shielded cable type is selected. (See Chapter 4, Setup for further information about shielded cables.)

For each of the 8 conductors and the Shield, Wiremap can indicate proper pin termination on each end, continuity to OMNIRemote, shorts between any two or more conductors, crossed pairs, reversed pairs, split pairs, and any other miswiring. For each pair, Wiremap displays the length. When a pair is faulty the length indicates the distance to the fault.

IREMAPDISPLAYS

The OMNIScanner icon on the left side indicates the wiring at the OMNIScanner end of the cable link.

CHAPTER 6: Diagnostics

OMNISCANNER

The OMNIRemote icon on the right side indicates the wiring at the OMNIRemote end of the cable link.

Correct connectivity:

The measured lengths of pairs 1-2, 3-6, 4-5, and 7-8 are shown on the left side of the Wiremap.

If the selected cable is shielded or screened, shield continuity will be measured, and if the shield fails the test, Wiremap will display the error.

Wire is open:

Wiremap checks the continuity of each wire.

In this example, there is no line between pin 5 at each end, which indicates a break in connection. Use the number on the left side of the screen to find the exact location of the open. For example if 36 ft is displayed, the open can be found 36 feet away from OMNIScanner.
