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,

OMNIScanner’s graphical user interface consists of a backlit LCD display, quick-
access 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 1-
Button Autotest feature, OMNIFiber measures loss (multimode and single-mode)
and length (multimode) over two fibers simultaneously. The measurements are

5.3.2 LENGTH/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

5.4 Fiber Optic Measurements with OMNIFiber
5.4.1 LENGTH/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.

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.

6.3 TDNXT
NEXT faults are diagnosed by using the TDNXT (Time Domain NEXT) function.
OMNIScanner uses TDNXT to determine the amount of NEXT as a function of
distance. TDNXT with new S-Band technology (Standard Connector band
technology) can help you to distinguish between connection and cable faults. It
assists you with diagnosis and troubleshooting of NEXT failures and the
verification of test cables, connectors, and plugs.
While the NEXT graph shows the link test limits and the frequency at which a
failure occurred, the TDNXT graph displays NEXT vs. distance.
S-Bands provide a time domain limit to verify that the connections are within
the desired category of performance. In a typical link, failures are a result of either

about units.)
Initially, the cursor is located at the point with the worst NEXT.
The NEXT at the cursor position relative to the S-Band, the corresponding pair
combination, and the distance to the cursor position are displayed above the
graph.

6.3.1 USING TDNXT TO DIAGNOSE A LINK
The S-Band limit lines provide an easy method to pinpoint faults located at the
connection or the cable. S-Bands allow you to determine if the connections in a
link meet the desired performance level. They are designed to match the standard
category of the selected Autotest.
A graph containing peaks that are located outside the S-bands at the connection
distance indicates that the connection and not the installed cable is the most likely
reason for failure.
If NEXT failed but the TDNXT graph displays peaks within the S-Bands at the
connection distance, the fault is caused by the cable portion of the link.
If failures occur at both ends of the link, use
or
to diagnose each
end. Failures at both ends of the link can interact.

6.4 TDRL
Return Loss is a measure of the amount of reflected energy in a link. Reflections
occur at points of impedance discontinuity, such as connectors, transitions from
patch cables to horizontal cables, and impedance structure within a cable.
Return Loss faults are diagnosed by using the TDRL (Time Domain Return
Loss) function. OMNIScanner uses TDRL to determine the amount of Return Loss
as a function of distance. TDRL with new S-band technology (Standard Connector
Band technology) can help you to distinguish and between connection faults and
cable faults. It assists you with diagnosis and troubleshooting of Return Loss
failures and the verification of test cables, connectors, and plugs.
While the Return Loss graph shows the link test limits and the frequency at
which a failure occurred, the TDRL graph displays Return Loss vs. distance.

OMNISCANNER
The fiber cables included with your OMNIFiber kit are duplex launch cables
with ST-style connectors. One fiber has white connector boots and the other fiber
has black boots.
8.3 The Reference Methods
OMNIFiber has ST-style connector port adapters. The following diagrams show
how to establish references with duplex launch cables for testing of ST-terminated
networks. For testing of networks terminated with different connector styles, please
call Black Box Technical Support at 724-746-5500.
It is very important that the transmitter (TX port) connections are not
disturbed after the reference value is established
NOTE
When a connector is removed and then reattached, it is unlikely to go
back into the exact same position. As a result, measurements will
change when connections are made or broken.
OMNIFiber measures two fibers of a duplex link in one Autotest operation.
Four reference values will be stored, two from OMNIScanner to OMNIRemote
(TX - RX), the others from OMNIRemote to OMNIScanner (TX - RX).
8.3.1 METHOD B: ONE JUMPER REFERENCE METHOD
This method is used when the link includes:
• the loss of one connection at the near end cross connect
• the loss of one connection at the far end cross connect/outlet
• the loss of the cable plant
TIA/EIA-568A, ISO 11801, and IEEE 802.3 (100BASE-X, 1000BASE-X) specify
this method.

8.3.4 METHOD A: TWO JUMPER REFERENCE METHOD IN LOOPBACK MODE
The OMNIFiber main can be used without the remote to make measurements on a
single fiber. In this state, the TX fiber is looped back to the RX port of the same
OMNIFiber Adapter.
NOTE
During the Autotest, the loss and length of the white fiber will be
subtracted from the length of the fiber under test. Since the loss in a
short jumper cable is negligible, the loss measurement of the fiber
under test will be accurate. The length measurement will be off by the
length of the jumper cable (about 2 meters). This primarily affects the
length accuracy of very short cables.
1. Connect the launch cable to the OMNIFiber. The black fiber attaches to the
TX (transmit) port and the white fiber to the RX (receive) port.
2. Use a connector adapter to mate the connections on the other end.

11. Multi Media Card
The MultiMediaCard is the world’s smallest solid state storage device. It weighs less
than two grams and is the size of a postage stamp (32 mm high by 24 mm wide and
1.4 mm thick). The card is available in 8 MB, 16 MB, and 32 MB capacities.
The MMC can store OMNIScanner2 test results that can then be uploaded to
Scanlink. Configurations that were creates with OMNIScanner Configuration
software can be downloaded onto the card for easy replacement of the current
OMNIScanner configuration. (See Chapter 9 for further information about
Uploading and Downloading.)
11.1 Portable Data
OMNIScanner2 can store data on a very small, removable MultiMediaCard. This
allows for unlimited expansion of memory capacity and transferral of test data
without taking OMNIScanner2 out of service.
Available MulitMediaCard readers and adapters allow data to be uploaded
directly to laptops or PCs.
Tests can be saved in OMNIScanner2’s internal flash memory or to the optional
removable MultiMediaCard. If the MultiMediaCard slot is empty, OMNIScanner
will automatically save the test results to the internal memory area.
When the MultiMediaCard is inserted, OMNIScanner will allow you to save the
selected project or
all test results to the card. See Chapter 7,
Results: Copying Results to a MultiMediaCard for further information about saving
results to the MMC.

APPENDIX B: Batteries
Appendix B: Batteries
B.1 Batteries
OMNIScanner and OMNIRemote are powered by rechargeable, recyclable battery
packs.
Under various state and local laws, it may be illegal to dispose of this battery
pack in the municipal waste stream. Check with your local solid waste officials for
details in your area for recycling options or proper disposal.
To remove the battery pack, place the instrument face down and slide the
arrow-shaped tab downward. Then lift the battery pack up towards you. To install
the battery pack, insert the two tabs on the top of the battery in the Scanner and
press down on the battery pack until it clicks into place.
The batteries have a limited number of recharge cycles. Typically, capacity is
warranted by the battery manufacturer for about 200 recharge cycles. The capacity
of a battery is highly dependent on the way it is recharged. Generally, batteries that
are fully discharged before the recharge cycle may have a longer life than those
subject to extended cycles of shallow discharge. Conditions of shallow discharge
promote a phenomenon known as voltage depression, which gives the appearance
of reduced capacity. Battery life can also be affected by the temperature conditions
under which charging is performed. Charging at room temperature (77°F/25°C)
maximizes the battery life.
OMNIScanner and OMNIRemote use a charging mechanism that minimizes
the effects of shallow discharging. To maximize battery life, the battery
temperature is monitored and maintained within limits during the charging
process. Charging under high temperature conditions may result in longer
recharge times or premature termination of charging.

OMNISCANNER
B.2 Battery Charging
Charging of the battery is enabled in the OMNIScanner and OMNIRemote
whenever the AC adapter is plugged in and the units are powered off.
The recharge time is typically 4.5 hours to completely charge a fully discharged
battery.
Charging is automatically terminated by the units when full capacity or over-
temperature conditions are reached. To enhance long-term life and capacity of the
battery, a maintenance and topping charge period starts right after the rapid
charge is completed. The charging status is displayed on both units. The graphic
LCD displays charging status on the OMNIScanner, while LEDs indicate the status
on the OMNIRemote unit.
Status conditions are as follows:
• Charge (RED) for OMNIRemote low-battery status
• Charge (GREEN) while OMNIRemote battery is charged
• Charge (GREEN) when battery is charged
B.3 Battery Tips
• Power off the unit before changing the battery pack. Charging is only enabled
when the unit is off.
• If not on AC power, the battery packs must be replaced within five minutes to
avoid loss of time and date in the OMNIScanner unit.
• If the display goes blank while the AC adapter is plugged in to the Scanner, it
indicates that the battery pack is on maintenance (“trickle”) charge.
• The average time to recharge the battery pack is about 4.5 hours.
• To maximize battery pack life, avoid extreme temperatures.
• Using OMNIScanner with the backlight turned ON causes increased battery
drain. (See Chapter 1, Introduction: OMNIScanners Keypad: Backlight.)
• Average daily life of the battery pack is about 10 hours.
• An external charger is also available. Contact Black Box for details.

APPENDIX C: OMNIFiber PASS/FAIL Criteria
Appendix C: OMNIFiber
PASS/FAIL Criteria
For the latest cable installation, international standards, and conformance
techniques:
http://cabletesting.com/Fiber_Standards.html
Formula 1: 568A Equation for 850 nm fiber:
(# of mated connections x 0.75)+(# of splices x 0.3)+(length x 3.75 dB/1000 m)=OLB*
Formula 2: 568A Equation for 1300 nm fiber:
(# of mated connections x 0.75)+(# of splices x 0.3)+(length x 1.5 dB/1000 m)=OLB*
Formula 3: 11801 Equation for 850 nm fiber:
(# of mated connections x 0.75)+(# of splices x 0.3)+(length x 3.5 dB/1000 m)=OLB*
Formula 4: 11801 Equation for 1300 nm fiber:
(# if mated connections x 0.75)+(# of splices x 0.3)+(length x 1 dB/1000 m)=OLB*
*Optical Link Budget (OLB) is the loss measured in a fiber link. Loss in the
connectors, the splices, and the cable are added up to the total link loss or OLB.
The TIA 568A Equation and the ISO 11801 Equation specify the OLB. Each has
certain PASS/FAIL criteria based on the number of connectors and splices located
along the cable to be tested. These amounts can be entered as test limits.
OMNIScanner then calculates optical power loss as follows: Max. Loss (dB) =
Cable Loss + Connector Loss + Splice Loss.
The Optical Link Budget (OLB) is the PASS/FAIL point in dB. The number of
connections and splices is entered in the first Autotest screen.
