PM-240-MTP Multifiber Optical Power Meter

PM-240-MTP Multifiber Optical Power Meter

The PM-240-MTP optical power meter is designed to measure absolute or relative optical power in optical networks terminated with 12/241 multifiber MTP/MPO connectors, in both SM and MM fibers. The tester can measure simultanously optical power level in all up to 12 fibers of MTP/MPO connectors, it can recognize “live” and “dark” fibers. It eliminates the need of fan-out from multi to single fiber connectors. Together with LS-240-MTP light source can measure Insertion loss in all 12 fibers at same time, in addition it is able to to check the polarity status of fibers interconnection between both MTP connectors. The input port ensures interconnection between measured MTP/MPO connector and 12/24 photodetectors. Due to physical contact between connectors the cleanness of both is required, preferably the visual check before measurement is suitable. 
The internal memory allows measurement storage and uploading of more than 500x 12-fibers cables including cable and fiber number, wavelength, absolute value or insertion loss. The Data Exporter software allows the user to export stored data to Excel sheet, or other applications.
The rechargeable Li-Pol battery ensures long term operation with a minimum service life of 2 years. Batteries can be charged via a USB port.
