The ZOOM 2 / Dual OWL Test Kit is ideal for LAN managers and installers who need to do simple attenuation tests on their multimode networks. The ZOOM 2 (Zeroed Output Optical Meter) is an economical fiber optic power meter. It provides accurate testing of multimode fiber cables. The 4-digit 7-segment LED display shows power readings with a resolution of 0.01dB. On-screen indicators display easurement units (dBm, dB, uW), as well as battery life. The ZOOM 2 comes configured with a 2.5mm universal connector for connection to ST or SC connectors, as well as any other fiber connector with a .5mm ferrule, and includes a 1.25mm adapter cap for LC connections. The Dual OWL is our 850/1300nm NIST traceable multimode light source. Its dual wavelength outputs are temperature stabilized for accurate measurements. The Dual OWL has two connector options: ST or SC.
