OWL Wave Tester, Dynamic Range 65dB, NIST traceable, 1mm photodetector with 2.5mm universal adapter

Reference#: 72206
Item#: OW-WT-1


The WaveTester is a high accuracy, high resolution, microprocessor controlled, optical power meter.  It has a 65dB dynamic range, and is NIST traceable at 850, 1300, 1310, and 1550nm, making it ideal for both singlemode and multimode fiber testing.   Additionally, it comes calibrated at 1490nm, allowing the meter to measure optical loss at the wavelengths used in Fiber To The Home (FTTH) PON networks.

It has an attractive handheld case with a backlit, graphic, liquid crystal display, and 4-key keypad for easy operation. It is offered with a 2.5mm universal fiber connector, will operate for over 250 hours on a standard high-capacity 9v battery, and has built-in auto shutdown.  The WaveTester will store reference values for each wavelength to be used for optical loss measurements, and can store up to 200 measured data points.  Stored data can be downloaded to our free OWL Reporter software to produce formatted certification reports.  Optionally, the battery charging port in the WaveTester can be replaced with a precision-coupled visual fault locator that is optimized for fiber optics.   Its high-intensity red laser allows for fiber identification up to 1.5  kilometers away .This optional VFL  port can also be used to  check for  faults within a few  feet  of its  launch  point.  When the bright red light encounters a fault, the light is deflected into the jacket, producing a red glow at the point of the fault.
