NetTek® OTDR

Features & Benefits

  • IntelliTrace™ Plus, Expert Results With the Push of One Button - Saves Training Time and Provides Better Results
  • Advanced Wave Shape Analysis Software Finds More Events - More Information On Your Critical Networks
  • Modular Platform Lets You Configure and Update Functions - Helps You Keep Up With Newer Technologies
  • Designed for Field Use - Reduces Maintenance Costs and Equipment Down Time
  • Advanced PC Report Generation Software - Combines Tests Into a Concise, Easy To Read Report To Save You Time


  • Fiber Optic Installation/Acceptance Testing
  • Optical System Fault Location
  • Physical Plant Documentation

The NetTek OTDR simplifies installation and maintenance testing of fiber optic cabling. The NetTek OTDR provides a total fiberoptic I&M test package, combining the NetTek platform with OTDR and power meter modules that provide outstanding performance and ease of use - all in a rugged package. The NetTek OTDR can help any user to achieve expert measurement results.

The IntelliTrace™ Plus Advantage

The NetTek OTDR modules use the Tektronix-patented IntelliTrace Plus technology. The IntelliTrace Plus function automatically optimizes test parameters so you don't have to. It gives you the best resolution on every section of the fiber while maximizing dynamic range.

The NetTek OTDR provides:

  • IntelliTrace Plus multi-pulsewidth, single-result auto test function to significantly reduce dead zone effects on your tests. See close events, including the first connector, at the same time you see events 200 km away
  • An easy-to-use interface, so even minimally trained users get good results

All these features combine to give you more information on your cables, with precise accuracy.

Modular Flexibility and Ease of Use

The NetTek Analyzer platform provides more flexibility for your optical test needs. The NetTek platform accepts up to four modules at once. You can mix and match modules to suit your needs.

Eight OTDR modules are available for varying applications. Current selections also include two PCMCIA-based power meters.

The NetTek OTDR is easy to use with a Windows touch-screen interface, automatic test routines and preprogrammed measurement thresholds to let even a novice user achieve expert results. All this in a rugged modular package.


The NetTek Analyzer platform contains the support and flexibility you need to manage your test and documentation needs.

The heart of the NetTek OTDR is the NetTek Analyzer platform. The platform is a full capability hand-held PC running Windows CE. You get the power, flexibility, and ease of use of Windows in a portable, durable platform. This is an advanced field test platform with the durability and intelligence you need in a field tool.


Windows CE operating system and pre-loaded, web-enabled standard applications support your current and future needs.

Windows-based test applications are easy to use in the field with a large color screen featuring a simple to use touch-screen interface.

The NetTek Analyzer can support up to four application modules. These can be different OTDRs or other optical or wireless test modules. Check with your local Tektronix representative or on the Tektronix web site for the latest test capabilities for the NetTek Analyzer.

The platform comes configured with multiple interfaces for your operation and documentation needs, like printer, serial and keyboard ports. In addition, it supports other interfaces using the 2 PCMCIA ports. Plug-ins such as LAN, modem, GPS and extra memory let you configure the unit to your needs, including supporting web-enabled applications.

The NetTek Analyzer is a true portable field tool in a durable package that meets Telcordia GR-196-CORE drop specifications and operates in the rugged environment you work in. It is small enough to take anywhere, and on fully charged batteries it can operate up to 8 hours.


Everything you need is on screen. Windows interface and touch-screen means you truly point (with your finger) and click.
Built-in Intelligence

The NetTek OTDR makes your job easy. Intelligence is built-in so you can concentrate on your communication system rather than on your test equipment.

Application-specific modules make buying the NetTek OTDR an intelligent decision. Choose from a variety of modules ranging from low cost/full performance all the way up to ultra-long range with truly world-class performance. Singlemode, multimode, whatever you need.


The IntelliTrace™ Plus function provides a better test and lets you configure the automatic operation to your needs.


NetTek OTDR includes smart software and hardware features to help automate the test process, making your job easier.

NetTek's IntelliTrace™ Plus uses a unique, patented multi-pulse width single test that lets you see all of your fiber system. See events at 10 meters at the same time you see the end of the fiber 200 km away.

On some OTDRs it may take up to four tests to see everything on your fiber. These OTDRs are limited to the resolution and range of one pulsewidth. This means you can look at nearby patch panels and splices, or you can look at the end of your fiber, but not at both simultaneously. Who has time for four tests on one fiber?

In addition, the NetTek OTDR uses wave-shape analysis algorithms that can perform an expert evaluation on the test, providing more insight into your measurements.

Running these tests is easy. For single tests, just push the OTDR Start Test button and the IntelliTrace Plus function figures out the rest. If you have lots of fibers to test, built-in macros help automate your testing.

By taking advantage of NetTek’s built-in intelligence:

  • You work more productively
  • You get better results
  • You need less test equipment training

YOPM Optical Power Meters


The YOPM, a PCMCIA-based Optical Power Meter, supports all your optical power measurement needs. It measures all common telecommunication wavelengths from 850 nm to 1625 nm. Easy saving of measurement data makes this an ideal tool for documenting networks.

Other data-storing power meters just let you store and view one measurement at a time. YOPM allows you to store and view tests in a configurable table. You can enter your system patch panel configuration so measurements match the way your patch panel is laid out, and not just as a list of numbers.

  • Tabular test results conform to your system patch panel layout, simplifying testing and analysis
  • Compatible with NetTek Analyzer platform for more flexibility than any data-storing power meter
  • PCMCIA-based meter leaves NetTek module slots free for other test functions
  • NIST Traceable accuracy
  • Two product offerings handle all major fiber wavelengths and power needs

TARGET1™ PC Analysis Software


TARGET1™ Trace mode lets you analyze individual tests.

TARGET1 Software - Trace Analysis Report Generation and Emulation Tool meets your optical test evaluation and report needs in one easy to use software tool.

  • Off-line analysis of OTDR results
  • Analysis of SOR compatible files
  • Remote control of NetTek optical modules
  • Automatic report generation
  • Interactive analysis of all tests in a fiber bundle
  • Output to printer, spreadsheet, html, word processor

This advanced, integrated software package can handle all stages of test evaluation from acquiring tests remotely to outputting summary reports to a web page.


TARGET1™ Report mode summarizes multiple tests in an easy to read format and exports to multiple formats.

Integrated reports linked to individual tests let you view the data for an entire fiber bundle instead of just one test at a time, making system acceptance and maintenance faster and easier than ever before. The software's Report Wizard guides you through the steps so that you can easily create and output professional reports.


TARGET1™ includes VirtualCE remote control of all NetTek functions.
