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.

FEATURES

? Available distance: 175km (Max) ? High power operation: 10mW

? High - side mode suppression ratio: 45dB (typ) ? High speed response (tr/tf): 120psec (typ)
