Chapter 1 - Introduction
TheDigital Solution forFiberandCopper
OMNI Scanner isthemostadvanced hand-held certificationanddiagnostic
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. OMNI Scanner 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 mea-
sures Length, Delay, Impedance, and Resistance on coaxial cabling.
OMNI Fiber MM(multimode)and OMNI Fiber SM(single-mode)expand the
tester’s capabilities to certify installed fiber links against TIA and ISO
standards.Fibercablingcanbeverifiedat 850, 1300, 1310, and 1550 nm
wavelengths.
TheGraphicalUserInterface
OMNI Scanner ’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.
OMNIRemote
For test and certification of twisted pair cabling, the OMNI Scanner requires
the OMNI Remote unit at the opposite end of the cabling link under test.
OMNI Scanner communicateswithOMNI Remote toobtainstatusand
perform measurements from both ends of the link.
OMNI Remote is equipped with a speaker to generate tones, and several
colored LEDs to indicate overall test results and status.

OMNIFiberTM
OMNI Fibertransforms OMNI ScannerandOMNIScanner2 intoafiberoptic
tool for testing and certification of multimode and single-mode fiber
premise networks. OMNI Fiber consists of two test heads that attach directly
ontoOMNI Scanner andOMNI Remote tobecomeapartofeach unit. Using

Upto1000Autotestscanbesavedtononvolatilememory. Saved results
can be easily uploaded to the PC with ScanlinkTM software.
ScanlinkTM Tools Software
PC-based software expands OMNI Scanner’s user interface and aids with
the management of projects. Scanlink Tools consist of the OMNIScanner
Configuration software, the Scanlink Upload software, and the OMNI-
Scanner Remote Control software. These programs allow you to store,
retrieve, manage, edit and print network cabling information. Scanlink Tools
provide the ability to create professional reports, remote control OMNI-
Scanner , and define cable and project configurations that can be down-
loadedtoOMNI Scanner .
