TYPE
NAME
ML9SM31
DESCRIPTION
ML9XX31 series are DFB (Distributed Feedback) laser diodes with a
monolithically integrated EA modulator, suitable light source for 10Gbps
or 2.5Gbps application (Single channel / DWDM).
Available wavelengths are from 1530nm to 1565nm with 0.8nm spacing.
ML9SM31 is supplied with the chip-on-carrier type package.
