OLTS Series Optical Loss Test Set combines an optical power meter with a dual or triple-wavelength light source to measure the optical loss, optical return loss (optional) and fiber distance for optical fiber network installation and maintenance of optical loss and optical return loss.

The optical power meter unit can automatically recognize the wavelength being launched and can perform an automatic bidirectional loss test on single fiber with pass/fail assessment. With its large data storage capacity, it is very convenient for field testing to store the test results and transfer the data to a computer via USB interface.

OLTS Series Optical Loss Test Set is the ideal optical loss tester to evaluate the optical fiber link IL & ORL in FTTx, LAN and CATV network
