M310 Enterprise OTDR

Rugged, lightweight and easy to hold, the M310 has a Touch and Test user interface that makes it easy for experts and novices to test and document fiber networks accurately and quickly. With dynamic range up to 38 dB, and 16 hour battery run time, M310 provides complete Tier 1 insertion loss and Tier 2 OTDR testing. Using pre-set Industry ISO/TIA standards or user set Pass/Fail thresholds, technicians are alerted to installation problems and failures in easy-to-interpret event table. Pass/Fail event table and trace are displayed on the same screen for easy correlation.

TruEvent Technology

The M310’s TruEvent technology is the result of extensive research into the properties of fiber optic cable events and provides a new level of event detection accuracy and reliability in field test equipment. Taking full advantage of the unit’s short dead zone and adding improved event accuracy, this is the best performing OTDR for enterprise and data center applications. With the push of a single button, users can be confident of obtaining accurate locations and measurements of all events, without the confusing introduction of false events

Testing and Inspection

The M310 is easy to use (Touch and Test®) and comes standard with an integrated source, power meter, visual fault locator, and inspection capability. No surprise ‘add-on’ charges for these commonly needed support functions.

  • Wave ID Source and Power Meter

    Enables multi-wavelength insertion loss testing with automatic wavelength synchronization, reducing test time and eliminating setup errors.

  • Source with Tone Generation

    Use with Optical Fiber Identifier to reliably distinguish in-service fibers from out-of-service fibers carrying test tone.

  • Visual Fault Locator

    Visibly locate far-end of specific fiber; precisely pinpoint macrobends or breaks in splice enclosures and cabinets.

Advanced Analysis (AA)

The AA option adds macro/microbend detection and bi-directional trace analysis to the M310 OTDR. M310s purchased with the AA option also include TRM 2.0 Advanced Analysis PC software.

  • Macro/Microbend

    Macro/Microbend detection helps technicians identify installation problems. Excessive bends or stress on fibers appear as increased attenuation at higher wavelengths. These bends or stresses are indicated on the Event Table with a special icon.

  • Bi-directional Trace Analysis

    Bi-directional trace analysis, used to resolve splice loss measurement errors due to fiber mismatch, takes the measurement of the loss in both directions, then calculates a two-way average to provide a more accurate loss measurement.

Data Storage and Reporting

Thousands of test results may be stored internally or on the supplied USB drive. Test results are transferable, via USB cable or USB drive, to a computer for viewing, printing, and analyzing with the supplied Windows® compatible TRM® 2.0 Basic Analysis and Documentation Software (Test Results Manager). The supplied TRM 2.0 Basic is licensed for installation on up to 5 PCs.
