TYPE
NAME ML925B11F / ML925B16F / ML925B22F
MITSUBISHI LASER DIODES
InGaAsP DFB LASER DIODES
DESCRIPTION
ML9XX11,ML9XX16 and ML9XX22 series are DFB
(Distributed Feedback) laser diodes emitting light beam with
emission wave length of 1470 ~ 1610nm.
They are well suited for light source in long distance digital
transmission application of coarse WDM.
They are hermetically sealed devices with the photo diode for
optical output monitoring.
