TYPE
NAME
InGaAsP DFB-LASER DIODE WITH EA MODULATOR
ML9SM41
DESCRIPTION
FEATURES
ML9XX41 series are DFB (Distributed Feedback) laser diodes with a
• Dispersion penalty less than 2dB at 9.95328Gbps, +1600ps/nm
monolithically integrated EA modulator, suitable light source for 10Gbps
• High extinction ratio (Min. 10dB at 9.95328Gbps)
application.
ML9SM41 is supplied with the chip-on-carrier type package.
• High - side mode suppression ratio (Typ. 40dB)
• High speed response (Typ. 30psec)
