The FTE7000A Optical Time Domain Reflectometer is designed for your CWDM networks with 4 CWDM lasers per unit.  These units have 36dB dynamic range to meet your CWDM testing requirements.   The FTE7000A series is a simple to operate touch screen unit with intuitive operation. As with our other FTE7000A units, it has an IEC61300-3-35 method “B” video inspection system for use with the optional VIS300 video probe.  
The FTE7000A-CWDM units have our rechargeable lithium Ion battery pack that supports up to 10 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 with our Android 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 and loss tests set measurements with the included “CertSoft” certification software suite.
