The OFT-920 ruggedized optical test set is designed for testing optical networks terminated with connectors in harsh environments. It combines both a light source and an optical power meter in one unit. This test set is ideal for the mining, petrochemical, and broadcast industries. The ruggedized aluminum case makes it perfect for field operations.
The memory capacity allows storage and uploading of up to 2000 measurements, including memory position or fiber number, wavelength, absolute value or relative value, and insertion loss. The tester supports memory download and test report generation. The rechargeable battery ensures long-term working with minimal operation costs.
