2.5Gbps DWDM InGaAsP DFB-LASER DIODE
TYPE
NAME
ML9SM11/ML9SM22
DESCRIPTION
FEATURES
• Available distance : 175km (Max)
ML9XX11 and ML9XX22 series are DWDM 2.5Gbps directly
modulated DFB (Distributed Feedback) laser diodes.
ML9xx11 and ML9xx22 are suitable light sources for 2.5Gbps
DWDM transmission in C-band and L-band wavelength ranges
respectively. Wavelengths can be chosen with 0.8nm spacing
according to ITU-T grid. Maximum 175km transmission distance
can be achievable.
• High power operation: 10mW
• High - side mode suppression ratio: 45dB (typ)
• High speed response (tr/tf) : 120psec (typ)
*1) Specification Note
ML9SM11 and ML9SM22 are supplied with the chip-on-carrier
type package.
