RXT-4113 xWDM OTDR Module

RXT-4113 xWDM OTDR Module

The RXT-4113 is the industry’s first combined CWDM/DWDM OTDR in a single test module. CWDM and DWDM (C-band) wavelength tuning with up to 500,000 data point sampling resolution offers unprecedented network characterization. Attenuation profiling and end-to-end connectivity using the single test port ensures maximum productivity.


  • CWDM wavelengths per ITU-T G.694.2 (18 channels)
  • DWDM wavelengths per ITU-T G.694.1 (C-band, 1527.99 to 1563.86 nm, Channel #s 17-62) in 50, 100 or 200 GHz steps
  • Sampling resolution up to 500,000 points
  • Event dead zone < 1m, Attenuation dead zone < 4m
  • Built-in DWDM wavelength locker with ± 2.5 GHz stability
  • High dynamic range for long haul fibers and testing through xWDM Mux/demux
  • TEC laser stabilization for hot and cold weather conditions
  • Telcordia GR-196 and SR-4731.sor file formats
  • Optional V-Scout mode – Intelligent Link Mapping using intuitive icons derived from multiple test acquisitions
  • Optional CWDM/DWDM Light Source via OTDR port
  • Optional broadband Optical Power Meter
  • Built-in launch fiber to characterize OTDR connections and short fiber spans
  • Universal 2.5 mm optical interface with inter-changeable optical adaptors (SC/FC/LC)


  • Advanced software architecture supports multiple test applications
  • VeExpress™ Cloud or Enterprise versions to maintain instrument firmware and manage test options or inventory
  • ReVeal™ PC and EZ Remote software for flexible remote control
  • Fiberizer Desktop PC software for advanced trace analysis and report generation
  • Fiberizer Cloud trace analysis and data management
  • R-server compatibility for centralized work force management and test results repository
  • Optional Fiber Inspection Scope (USB) with single or multi-fiber (MPO/MTP) support


  • High resolution, 7” full color TFT touch-screen viewable in any lighting condition
  • Connectivity via 10/100Base-T Management interface, WiFi™, Bluetooth®, or 3G/LTE for back office applications
  • Intelligent fan operation with built-in temperature sensor
  • Interchangeable Li-ion battery pack for extended test time
  • USB-A Interface for USB flash drives, USB wireless dongles and fiber inspection probe connection
  • Optional built-in GPS module for Geotagging OTDR traces
