Miscellaneous Text:

Three-second Autotest optical loss measurement of two fibers at two wavelengths with distance measurement and optical loss budget calculation. Provides automatic Pass/Fail analysis to industry standards or custom test limits. Identifies incorrect test procedures resulting in negative loss readings. Double ended Pass/Fail certification of fiber optic connector end faces. Graphical indication of problem areas on fiber end faces due to contamination, pits, chips and scratches.

Interchangeable power meter adapters available for all typical connector types (SC, ST, LC and FC) to enable the most accurate 1-jumper reference method. Built-in visual fault locator for basic troubleshooting and polarity determination. Dual wavelength measurement capability on a single fiber allows the tester to be used in applications that require only one fiber link. Compliant with TIA- 526-14-B and IEC 61280-4-1 Encircled Flux requirements with no additional equipment or procedures. Integrated Wi-Fi allows you to easily upload results.

New Miscellaneous Text:

Single-port, simultaneous dual-wavelength feature completes testing in half the time and saves measurements from both wavelengths into one record

Additional wavelengths of 1490 and 1625 nm feature emits an audible tone and displays an icon when a live fiber is detected, eliminating the need to set up a measurement

Remote enables one individual to quickly identify cable connections or routings (especially useful at patch panels), eliminating the need for multiple technicians on opposite ends of a fiber link to match color combinations

Min/Max capability automates precision tracking of intermittent power fluctuations

Large internal memory save 1000 results which enables continuous testing and recording

Cable Test Management software helps to analyze test results and create professional test reports

Various kit configurations for all first line fiber handling needs, including fiber verification, inspection, and cleaning - all housed in a professional, rugged carrying case
