(888) U.S.-OTDRS

The FTE7000A-EXT Optical Time Domain Reflectometer is a 1310/1550nm singlemode unit with 38/39dB. This OTDR offers abundant range to meet your metro, FTTX and MDU requirements. The FTE7000A series is a simple to operate touch screen unit with a bright color display. As with our other FTE7000A units, it has an auto centering and auto Pass Fail video inspection system for use with the optional VIS300 video probe.

The FTE7000A-EXT unit has our rechargeable lithium Ion battery pack that supports up to 12 hours of operation with a quick 2 hour recharge cycle. This unit includes all the features expected in today’s hand held OTDR and more; bright color touch screen, project management, file storage, Fib-R-Map schematic event analysis, pass/fail threshold settings and onboard context sensitive Express Help system to keep the learning curve short and simple.

This OTDR may also be operated via Bluetooth with our Andriod app which is a real time application for your compatible Android tablet or phone.

The FTE7000A weighs less then 2.0 pounds, and with a hardened water resistant enclosure in a sturdy rubber boot, this OTDR is great for all working conditions. You can print professional reports that include; Fib-R-Map schematic analysis, loss tests set measurements and video inspection images with the included “CertSoft” certification software suite.
