Vicom OTDR Selection Guide


All-in-one integrated dual bay solution automating fibre/optical test and certification

Telecommunication network topologies and technologies are evolving rapidly to respond to increased bandwidth requirements. Installers and service providers must equip technicians with scalable and easy-to-use test tools that addresses a wide range of up-to-date optical test applications quickly and accurately under all field conditions.



Purpose-Built for Engineers, Technicians, Installers and Contractors

The VIAVI MTS-4000 is the optical test platform engineers, technicians, installers and contractors can rely on, providing:

  • An easy-to-use solution with intuitive icon-based graphical user interface (GUI) and multi-touch screen requiring minimal training

  • A compact platform with field-replaceable modules covering multiple optical test functions (OTDRs, optical power & loss testing, Optical Spectrum Analyzer (OSA), etc…) that enable complete optical network qualification.

  • Optimum workflow and operation within the platform or through the cloud with VIAVI StrataSync and SmartAccess Anywhere

Key Benefits

  • Certify the fibre physical layer of FTTx/PON, access, metro and enterprise networks
  • Two field-replaceable modules increase flexibility
  • Smarter and faster field testing with tablet user interface
  • Advanced cloud support and remote connectivity

Key Features

  • Dual-modular handheld platform
  • Large 9-inch high visibility touchscreen with permanent function keys
  • Essential tools integrated and supported in the platform (visual fault locator, optical power meter, optical microscope and talkset)
  • Flexible connectivity; Ethernet, WiFi, Bluetooth
  • Smart Access Anywhere (SAA) for remote control & field tech support
  • StrataSync enabled — centralized cloud based asset, configuration, test data and workflow management

Smart Link Mapper

"If the OTDR were invented today, it would look like VIAVI's Smart Link Mapper"

The SLM intelligent optical software application helps technicians use an OTDR more effectively, without the need to understand or interpret OTDR results. Each event is displayed as an icon giving users a schematic view of the entire link, known as SmartLink. SLM can completely correlate to the original OTDR trace as experts desire. With this common approach to simplify OTDR testing and streamline the procedures, four tailored SLM OTDR applications are available for different network types. For more details about each of the applications (Enterprise-SLM, FTTA-SLM, FTTH-SLM and Cable-SLM), visit the Options tab above page.

Key Benefits

  • Eliminates OTDR results interpretation complexity Immediately diagnoses problems
  • Reduces human error
  • Improves OTDR testing time and reliability
  • Reduces truck rolls, re-test, and cable waste
  • Dedicated apps focused for Enterprise, high density fiber Cable, FTTA and Passive Optical Network (PON) / FTTH

Key Features

  • Directly correlates SmartLink view results and OTDR trace
  • Automatic pass/fail results
  • Eliminates the need for OTDR expertise
  • Compatible with all multimode/single-mode and OTDR modules
  • Upgradable on site

Multi-Fibre MPO Switch Module

All-in-one integrated solution automating OTDR tests of MPO cables

Well suited for use in high-density fiber environments, multi-fibre MPO cables eliminate the expense of running individual patch cords for each service turn-up. Widely used in Data Centers interconnects, MPO cables are spreading into telecom access applications such as FTTH, FTTA or C-RAN. The use of an MPO switch is the best way to accurately and quickly characterize individual fibers of an MPO cables with an OTDR.

Key Benefits

  • All-in-one and integrated solution for multi-fibre MPO cable characterization, certification and troubleshooting
  • Replaces multi-fibre fan-out / break-out patchcords / cables
  • Smart Link Mapper (SLM) Software applications automate test workflow

Key Features

  • Singlemode 1x 12 MPO Switch Module
  • Pinned APC MPO port for connection to MPO links to be tested
  • SC/APC port for connection to OTDR test port
  • Automatically controlled by the OTDR
  • Enterprise-SLM and Cable-SLM Ready
  • Compatible with MTS-4000V2 Platform

EM4000HVT-KIT6 1 SM 1310/1550/1625 46/45/44 130-150 

NOTE: “Distance” above refers to the approximate fibre distance that can accurately be certified based on 0.2dB/km fibre loss @ 1550nm (0.22dB for 1625/1650 only OTDRs) & 0.1dB splices every 2km. Note too that for the same distance, test times reduce with dynamic range increase – roughly half the test time for every 2-3dB increase in dynamic range.
