ML9xx19 SERIES
TYPE
NAME ML925B19F
MITSUBISHI LASER DIODES
2.5Gb
s InGaAsP DFB LASER DIODE
DESCRIPTION
ML9xx19 series are uncooled DFB (Distributed Feedback) laser
diodes for 2.5Gbps transmission emitting light beam at 1550nm.
/4 shifted grating structure is employed to obtain excellent SMSR
erformance under 2.5Gbps modulation. Furthermore, ML9xx19 can
operate in the wide temperature range form 0ºC to 70ºC without any
temperature control.
