The OFT-850K set consists of a SOURCE and TESTER unit. This hybrid cable tester is designed for testing loss in optical fibers and checking the continuity of copper pairs in hybrid cables. It combines an optical light source on one side, an optical power meter on the other side, and a copper wires checker. It is ideal for testing hybrid systems based on cables that include both optical fibers and copper wires. The ruggedized aluminum case makes the unit perfect for field operations. The memory capacity allows storage and uploading of more than 1000 measurements, including cable number, results of metallic wires check, and optical power value or insertion loss. The tester supports memory download and test report generation. The lithium rechargeable battery ensures long-term working with minimal operation costs.
