TYPE
NAME
InGaAsP DFB-LASER DIODE WITH EA MODULATOR
ML9SM31
DESCRIPTION
FEATURES
ML9XX31 series are DFB (Distributed Feedback) laser diodes with a
• Available distance
monolithically integrated EA modulator, suitable light source for 10Gbps
ML9SM31-01 series : 50km(Max) at 10Gbps
or 2.5Gbps application (Single channel / DWDM).
ML9SM31-02 series : 700km(Max) at 2.5Gbps
• High extinction ratio (Min. 11dB at 2.5Gbps, Typ. 11dB at 10Gbps)
Available wavelengths are from 1530nm to 1565nm with 0.8nm spacing.
ML9SM31 is supplied with the chip-on-carrier type package.
• High - side mode suppression ratio (Typ. 40dB)
• High speed response (Typ. 30psec)
APPLICATION
