The ZOOM 2 / Laser OWL Test Kit is ideal for LAN managers and installers who need to do simple attenuation tests on their singlemode networks. The ZOOM 2 (Zeroed Output Optical Meter) is an economical fiber optic power meter. It provides accurate testing of 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 Laser OWL is a 1310/1550nm NIST traceable singlemode light source. Its dual wavelength outputs are temperature-stabilized for accurate measurements. The Laser OWL comes configured with SC connectors.
