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.
