MITSUBISHI LASER DIODES
ML7xx16 SERIES
2.5Gbps InGaAsP DFB LASER DIODE
TYPE NAME
ML725B16F
FEATURES
/4 phase shifted grating structure Wide temperature range operation (-20ºC to 85ºC ) High side-mode-suppression-ratio (typical 45dB) High resonance frequency (typical 11GHz)
DESCRIPTION
ML7xx16 series are uncooled DFB (Distributed Feedback) laser diodes for 2.5Gbps transmission emitting light beam at 1310nm. /4 shifted grating structure is employed to obtain excellent SMSR performance under 2.5Gbps modulation. Furthermore, ML7xx16 can operate in the wide temperature range form -20ºC to 85ºC without any temperature control.
