ML9xx45 SERIES
1550,1520nm InGaAsP FP LASER DIODES
TYPE _{ML920J45S , ML920K45S, ML920Y45S}
NAME
ML925B45F , ML925C45F
DESCRIPTION
ML9XX45 series are InGaAsP laser diodes which provide
a stable, single transverse mode oscillation with emission
wavelength of 1550nm and standard continuous light output
of 5mW.
ML9XX45 are hermetically sealed devices having the photo
diode for optical output monitoring. This is suitable for such
applications as FTTH (Fiber to the Home)systems.
