M310 Enterprise OTDR

The M310 OTDR is specifically designed to address the technical challenges associated with today’s enterprise network architectures. The M310 integrates AFL's TruEvent™ Technology -- advanced event analysis software to more accurately detect, locate and measure network events - allowing users to confidently determine where losses meet or exceed specification.

The M310 is easy to use (Touch and Test®), comes standard with integrated Source, Power Meter and VFL, and is compatible with DFS1 connector inspection probe. No surprise 'add-on' charges for these commonly needed support functions.

Industry Leading TruEvent™ Technology - Provides a new level of accuracy and reliability in event analysis. This is the best performing OTDR for enterprise and data center applications.

Short dead zones to validate and troubleshoot typical Data Center and Enterprise networks

  • Event Dead Zones 0.8m
  • Attenuation Dead-zones < 3 m

Built-in Optical Light Source (OLS) - Provide light source for Tier 1 testing convenience
Built-in Optical Power Meter (OPM) - Test and store both Tier 1 and Tier 2 results in one unit
Built-in Visual Fault Locator (VFL) - Quickly identify fiber faults and verify polarity
Front Panel and First Connector checks - Verify launch quality to help users obtain better OTDR trace results
Live Fiber Detection - Detects in-service fibers to protect equipment and prevent testing the wrong fiber
Dynamic Range - The right capability for Enterprise networks

  • 38 dB Single-mode
  • 30 dB Multimode

Inspection ready - Plug in the DFS1 Digital FiberScope to inspect connectors and ensure there are no dirty or damaged connections in the network
Fast, Real Time OTDR mode - Use in troubleshooting or splicing applications
Truly hand-held - Compact, rugged product packaging is designed for outside use and cramped inside plant environments.
Easy to read results - M310 OTDR reports both the traditional OTDR trace and an event table clearly showing pass/fail results on one screen. This easy to interpret table allows less skilled technicians to effectively use the OTDR.
International Language Support - User interface available in English, Chinese, French, German, Italian, Polish, Portuguese, Spanish and Turkish

M310 Touch and Test® supports users of all levels

Full Auto Mode – Connect and press test. M310 will detect fiber and set recommended test parameters. Perfect for novice technicians or repair techs quickly looking for faults on fiber spans of unknown length.

Auto-Once Mode – Designed for testing cables with multiple fibers. M310 performs a full auto test on the first fiber and retains recommended settings allowing fast testing of subsequent fibers.

Expert Mode – Provides access to testing parameters for experienced users to setup optimal testing scenarios for specific networks.

Real-Time Mode – Continuous OTDR operation and display update, allows users to dynamically change networks while monitoring OTDR trace results. Example: relaxing fiber bends to reduce attenuation loss.

Data Storage and Reporting Capabilities (TRM™)

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 software - TRM™ 2.0 Basic Analysis and Documentation Software (Test Results Manager). Acceptance reports generated using TRM 2.0 can include OTDR traces with summary and event information with or without pass/fail indication, event maps, loss/power measurement tables and end-face images.

Advanced Analysis Software

The Advanced Analysis software option integrates macro/microbend detection and bi-directional trace analysis into the M310, and includes TRM 2.0 Advanced Analysis PC software.

  • Macro/Microbend detection - The detection helps technicians identify installation problems. Excessive bends or stress on fibers will show up as increased attenuation at higher wavelengths. These bends or stresses are indicated on the Event Table with a special icon.
  • Bi-directional trace analysis - The analysis is used to resolve errors due to things like mis-matched fibers, takes the measurement of the loss in both directions, then calculates a two-way average of the OTDR's data, which is the true loss of the event.


  • Industry Leading TruEvent™ analysis ensures event reporting accuracy
  • Short dead zones provide testing of closely spaced events
  • Integrated Source, Power Meter and VFL
  • Live fiber detection prevents damage to network equipment
  • Front Panel and First Connector Check ensures accurate measurements

  • Dynamic Range up to 38 dB
  • Multiple languages supported
  • 16 hour battery run time
  • Automatic Pass/Fail Analysis (TIA/ISO)


  • Test, troubleshoot and document networks with closely spaced events
  • Tier 1 and Tier 2 testing and certification of SM and MM networks
  • Enterprise network, Data Center, LAN/WAN
  • Document and create standards compliant acceptance reports with TRM™ 2.0, companion PC software
  • Test and troubleshoot networks up to 250 km
  • Test and certify campus & central office networks, and Distributed Antenna Systems (DAS) fiber infrastructure
  • Inspection of fiber endfaces using DFS1 Digital FiberScope
