OFT-820 Loss Test Set
The OFT-820-POF series Loss Test Set is designed for POF – Plastic Optical Fiber network testing. It combines two optical test equipment – Light Source and Power Meter in the same box. The tester can be used as portable power meter or as USB probe, or as part of a testing workstation. The optical Light Source fulfills all the necessary technical requirements for field POF network measurements. The source sends optical light into output interface, available in working wavelengths 650 nm and 850 nm. The optical Power Meter is designed to measure absolute or relative optical power in POF networks.
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. The rechargeable battery ensures long-term working with a minimum lifetime of 2 years. The removable and changeable IN/OUT adapters allow easy maintenance and cleaning of both ports, making the tester universal in a wide range of applications with various POF connectors. The design of both input and output adapters is the same.
