One Core Loop Tester

One Core Loop Tester

DAMUL is an innovative and portable optical power checker accompanying 1-core loop back function. DAMUL can check SFP TX and RX power level by simply inserting SFP into it. If you use UPM (Universal SFP-typed Power checker Module) optionally provided, DAMUL can measure optical power. Also, when using SPM (SFP-typed Power checker Module) optionally provided, DAMUL can identify 18 CWDM wavelengths as well as its power automatically. DAMUL provide users high productivity for optical power checking work on fiber optic systems such as WDM-PON.
