MITSUBISHI LASER DIODES
ML9XX17 SERIES
InGaAsP MQW-DFB LASER DIODE WITH EA MODULATOR
TYPE
NAME
DESCRIPTION
ML9XX17 series are DFB (Distributed Feedback) laser
diodes with a monolithcally integrated EA (Electro-Absorption)
modulator emitting light beam at 1550nm.
The laser is suitable to a light source for use in ultra-long-haul
transmission over 700km.
