The ZOOM 2 / Dual OWL / Laser OWL Test Kit is ideal for LAN managers and installers who need to do simple attenuation tests on their multimode and single-mode networks. The ZOOM 2 (Zeroed Output Optical Meter) is an economical fiber optic power meter. It provides accurate testing of multimode and singlemode fiber cables. The 4-digit 7-segment LCD displays power readings with a resolution of 0.01dB. On-screen indicators display measurement 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 2.5mm ferrule, and includes a 1.25mm adapter cap for LC connections. The Dual OWL is a 850/1300nm NIST traceable multimode light source. Its dual-wavelength outputs are temperaturestabilized for accurate measurements. The Dual OWL comes configured with SC connectors. The Laser OWL is a NIST traceable singlemode light source. Its dual-wavelength outputs (1310nm / 1550nm) are temperature-stabilized for accurate measurements, and come configured in SC connectors.
