ML9xx37 SERIES
High Power InGaAsP DFB LASER DIODE
TYPE
NAME
ML99237/ML9SM37
APPLICATION
CW light source for external modulator
DESCRIPTION
ML9xx37 series are high power DFB (Distributed Feedback) laser
diodes for optical transmission emitting light beam at 1550nm.
ML9xx37 achieves 60mW CW operation with stable single
longitudinal mode oscillation and narrow linewidth. ML9xx37 is a
suitable light source for a 10Gbps/40Gbps external modulator.
