| MITSUBISHI LASER DIODES ML9XX31 SERIES Notice: Some parametric limits are subject to change. InGaAsP DFB-LASER DIODE WITH EA MODULATOR TYPE NAME DESCRIPTION ML9SM31 FEATURES * Available distance ML9SM31-01 series : 50km(Max) at 10Gbps ML9SM31-02 series : 700km(Max) at 2.5Gbps * High extinction ratio (Min. 11dB at 2.5Gbps, Typ. 11dB at 10Gbps) * High - side mode suppression ratio (Typ. 40dB) * High speed response (Typ. 30psec) 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.
