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

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.



Power Utilities WAN/LAN c37.94 Testing

The VIAVI MTS-5800 delivers power utility operators the ability to measure reliability on the WAN backbone and on the substation LAN. As utilities transition from T1/SONET/IRIG-B to Ethernet /MPLS, the MTS-5800 platform gives technicians all the test capabilities necessary to ensure high network performance, including Ethernet/IP with multiple VLANs, MPLS, and 1588v2 (PTP).

In addition, the MTS-5800 family allows technicians to test WAN circuits and the substation fiber plant for cleanliness and to confirm that connectors, splices & patch panels are functioning properly. Tele-protection interfaces, specifically C37.94 optical power and loss in order, that connect power system equipment to Intelligent Electrical devices (IEDs) should be Bit Error Rate tested to confirm that EMI is not negatively impacting communications.
