DESCRIPTION
ML9XX35 series are InGaAsP laser diodes which provides
a stable, single transverse mode oscillation with emission
wavelength of 1550nm and standard continuous light output
of 5mW.
ML9XX35 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.
