MultiTest Module — FTB-3930


Sorry this product is discontinued

Provides fully automated bidirectional loss test results in 10 seconds for up to three wavelengths, as well as automatic ORL and fiber-length measurement.

Key features

  • Two FasTesT ports: a three-wavelength singlemode port, including either 1625 nm or 1490 nm, and an optional two-wavelength multimode port, for a total of up to five wavelengths
  • Visual IL and ORL pass/fail analysis
  • Compatible with both the FTB-500 and FTB-200 platforms
  • FTTx ready: allows for the testing of passive optical networks (PONs) at 1310 nm, 1490 nm and 1550 nm, the three wavelengths recommended by the ITU-T (G.983.3) for PONs
  • Three-year warranty and recommended calibration interval, error-free testing and minimized training time


  • Bidirectional link-loss and ORL characterization
  • High-fiber-count network construction
  • FTTx construction

Housed in either the FTB-500 Platform or the FTB-200 Compact Platform, the FTB-3930 MultiTest Module provides fully automated bidirectional loss test results in 10 seconds for up to three wavelengths, as well as automatic ORL and fiber-length measurement. It combines up to five light sources, a power meter, a visual fault locator and a full-duplex digital talk set—all this and more in a single modular instrument built for today’s fiber-optic testing requirements.

This unit easily and efficiently provides complete, high-quality test documentation. Its data logging and management features help users quickly access and download test results to any PC for in-depth analysis and first-class report generation. The FTB-3930 MultiTest Module is a next-generation automated loss test set designed for network service providers, installers and cable operators.

An FTTx Test Solution

This product is part of EXFO's series of FTTx optical test products. It allows for the testing of passive optical networks (PONs) at the three main wavelengths (1310, 1490 and 1550 nm) used in fiber-to-the-home (FTTH) and fiber-to-the-premises (FTTP) networks and complies with the ITU-T G.983 and G.984 Recommendation series and the IEEE 802.3ah standard.

FTTx Mode—Optimized for Testing Passive Optical Networks (PONs)

This mode lets you configure your FTB-3930 to suit your FTTx wavelengths and test-unit locations, as well as choose your preferred data presentation options for on-screen display or report generation. Benefits include the display of test data according to FTTx terminology, as well as similar test-data presentation, regardless of the location of main and remote units.

A Single Tool for All Backreflection, Fiber-Length and Loss Measurement Needs

Because learning how to operate only one instrument is easier and much faster, test specialists should choose an all-in-one tool that enables them to perform tasks such as installing long-haul high-speed networks, testing 1310/1490/1550 nm transmission in FTTH networks, performing multimode testing in enterprise networks, etc.—a do-it-all solution such as the FTB-3930 MultiTest Module.

Key Advantages for All Network Types

The FTB-3930 module delivers fast, three-wavelength loss and ORL results based on user-configurable pass/fail thresholds, for error-free testing. It is the only unit of its kind designed for testing both multimode and singlemode fiber. What’s more, it comes with a GeX detector, for high-power measurement up to +26 dBm. Thanks to user-friendly features and various options (video fiber inspection probe, talk set, visual fault locator, etc.), the FTB-3930 MultiTest Module requires little training and offers the flexibility that field crews look for.
