M210e Enterprise OTDR

The M210e is the inspection ready OTDR that combines OTDR, OPM and VFL capability with a proven, easy to operate and understand interface. The M210e offers the intuitive Touch and Test™ user interface in a rugged, lightweight, easy-to-hold package ready for field use. Touch and Test simplifies the M210e user experience, minimizes human errors and reduces training time by providing one-touch access to the all major functions of the OTDR. The M210e allows setting Pass/Fail thresholds to industry standard TIA/ISO or user-values and automatically alerts users of failing fibers, enabling both experts and novice technicians to complete jobs more accurately and in less time.

Available as a single-mode, multimode, or single-mode/multimode model, the M210e comes in either a soft or hard case, also as part of kit for testing, inspection, and certification. The M210e is ideal for testing, analyzing and troubleshooting enterprise, LAN/WAN campus and military facilities. 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.

M210e Touch and Test® supports users of all levels

Full Auto Mode – Connect and press test. M210e 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. M210e performs a full auto test on the first fiber and retains recommended settings allowing fast expert-speed 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.
Top menu level touch screen access to major test modes allow users to test networks faster- no time wasted with complicated menu structures. The M210e provides one-touch access to OTDR and OPM test modes and DFS inspection mode.
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™ (Test Results Manager). Acceptance reports generated using TRM 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.
