M710 Multifunction OTDRs

The M710 OTDR from AFL combines ease of use (Touch and Test™) and high performance in a rugged, large display package. With singlemode dynamic ranges up to 44 dB and a MM/SM QUAD option, the M710 OTDR is ideal for testing and troubleshooting LAN/WAN, metro and long haul networks. Industry leading dead zones enhance the user’s ability to locate and measure events.

The M710 models utilize AFL’s industry leading TruEvent technology to provide a new level of accuracy and reliability in event analysis. LinkMap visualizes test results for easy and quick interpretation.

Touch and Test simplifies the M710 user experience, minimizes human errors and reduces training time by providing one-touch access to all OTDR test modes, OPM testing, Results Management and Job Creation menus. The M710 allows setting Pass/Fail thresholds to industry standard TIA/ISO values or user defined criteria and will automatically alert users of failing fibers. Touch and Test enables any technician to complete jobs more accurately and in less time, making it the ideal field test tool.


Industry Leading TruEvent™ Technology –
Provides a new level of accuracy and reliability in event analysis.

Short dead zones – to validate and troubleshoot networks

  • Event Dead Zones 0.8m
  •  Attenuation Dead-zones < 4 m

Superior Dynamic Range – Higher dynamic range means you can test short networks with narrower pulse widths (better resolution), as well as test longer networks. Up to 44 dB, the OTDR can handle from complex LAN network to 220km Long Haul network.

Easy to read results with LinkMap™ – LinkMap with Pass/Fail simplifies network troubleshooting and enables even novice users to easily and accurately troubleshoot optical networks.

Built-in Optical Power Meter (OPM), Visual Fault Locator (VFL), and Inspection ready – all in one to help you face fiber network testing challenges.

Bright 6.5’ Color Display with Long Laster Battery -.

International Language Support – User interface available in English, Chinese, French, German, Italian, Polish, Portuguese, Spanish and Turkish

Data Storage and Reporting Capabilities (TRM™ 2.0) – Acceptance reports generated using TRM 2.0 can include OTDR traces with summary and event information, pass/fail indication, event maps, loss/power measurement tables and end-face images.

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 — OTDR splice measurements on networks containing different fiber type may result in ‘gainer’ and excess loss splices where mismatched fibers are spliced.  More accurate splice loss measurements are obtained by averaging OTDR traces obtained in each direction.  M710 Advanced Analysis option integrates bi-directional averaging within the OTDR.
