| MITSUBISHI LASER DIODES ML7xx19 SERIES Notice: Some parametric limits are subject to change. 1310nm InGaAsP FP LASER DIODES TYPE NAME DESCRIPTION ML720J19S, ML720K19S, ML728C19S ML725B19F, ML725C19F FEATURES *1310nm typical emission wavelength, FP-LDs *Wide temperature range operation(-40 to 85C) *5.6mm TO-CA N package Flat window cap : ML720J19S, ML725B19F Ball lens cap : ML720K19S, ML725C19F *3.8mm TO-CA N package Ball lens cap : ML728C19S ML7XX19 series are InGaAsP laser diodes which provide a stable, single transverse mode oscillation with emission wavelength of 1310nm and standard continuous light output of 5mW. ML7XX19 are hermetically sealed devices having the photo diode for optical output monitoring. This is suitable for such applications as the light sources for optical communication systems up to 2.5Gbps transmission applications.
