MITSUBISHI LASER DIODES
ML9XX11/ML9XX22 SERIES
2.5Gbps DWDM InGaAsP DFB-LASER DIODE
TYPE NAME
ML9SM11/ML9SM22
DESCRIPTION
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. Wavelength can be chosen with 0.8nm spacing according to ITU-T grid. Maximum 175km transmission distance can be achievable.
ML9XX11 and ML9XX22 are supplied with the chip-on-carrier type package.
