The ZOOM II / Dual OWL 850 Test Kit is ideal for LAN managers and installers who need to do simple attenuation tests on their Multimode networks. The ZOOM II (Zeroed Output Optical Meter) is an economical fiber optic power meter. It provides accurate testing of multimode fiber cables when used with a 850nm multimode light source. 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 II 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. The Dual OWL 850 is our 850nm NIST traceable Multimode light source. Its 850nm output is temperature-stabilized for accurate measurements. The Dual OWL 850 has two connector options: ST or SC.
