Ando AQ7250 SM Fiber Mini OTDR
Today's users demand the accurate transmission of extremely high-quality signals, so it is essential to use superior optical fibers. It is also vital to conduct accurate loss measurements when laying and maintaining optical fiber cables, and when checking for faults.
In addition to being capable of measuring loss and detecting faults in optical fibers, OTDRs must be compact and lightweight for easy handling in the field, and able to complete measurements quickly.
The mini-OTDR AQ7250 and optical unit meet all these requirements for building and maintaining optical fiber systems, as well as manufacturing and inspecting optical fiber material.
Compact, lightweight, and battery-powered, the AQ7250 offers a range of functions and capabilities ideal for field use. Its exceptionally wide dynamic range is particularly effective for measuring lines over long distances, as well as lines with heavy loss. In addition, an improved measurement algorithm drastically reduces measurement processing time.
A wide range of optional equipment enables a single unit to be used for measurements on a variety of optical fiber lines. An optional high-speed printer or optical switch unit, as well as a visible light source or optical power meter can be installed on the main unit of the AQ7250. This eliminates the need to carry several measuring instruments on a single field mission. This mini-OTDR, like its predecessors, has a large, viewer-friendly color screen and a 3.5-inch floppy disk drive as standard equipment.
