OFT-920 Ruggedized Optical Test Set
The OFT-920 ruggedized optical test set is designed for testing of optical networks terminated with connectors operating in harsh environment. It combines both light source and optical power meter in one common box. The test set is designed to meet the mining, petrochemical and broadcast industry demand. The ruggedized aluminium case makes the unit ideal for field operation. 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 generating. The rechargeable battery ensures long term working with minimal operation costs.
