The OFT-840 series optical Loss Test Set with optical Return Loss (RL) combines optical Light Source, Power Meter and Return Loss testing in the same box. The optical Light Source fulfills all the necessary technical requirements for field equipment. Available in two working wavelengths: 1310 or 1550 nm. The optical Power Meter is designed to measure absolute or relative optical power in optical networks. The optical RL function provides extended measurement range with improved linearity. The memory capacity allows storage and uploading of up to 3000 measurements including memory position or fiber number, wavelength, absolute value or relative value and insertion loss. The SmartProtocol PC evaluation software supports memory download, test report generation and Data Exporter for data download to Excel sheet.
