The OFT-820N series optical Loss Test Set combines two optical test equipments – Light Source and Power Meter in the same box. The optical Light Source fulfills all the necessary technical requirements for field equipment. Available in various working wavelengths combinations: 850, 1300, 1310, 1490, 1550 and 1625 nm. The optical Power Meter is designed to measure absolute or relative optical power in optical networks. The changeable adaptor design allows the simple exchange of optical connectors according actual need.
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 rechargeable battery ensures long term working with a minimum life time of 5 years.
