MITSUBISHI LASER DIODES
ML9xx45 SERIES
1550,1520nm InGaAsP FP LASER DIODES
TYPE
NAME
ML920J45S , ML920K45S, ML920Y45S
ML925B45F , ML925C45F
DESCRIPTION
ML9XX45 series are InGaAsP laser diodes which provide
a stable, single transverse mode oscillation with emission
wavelength of 1550nm and standard continuous light output
of 5mW.
ML9XX45 are hermetically sealed devices having the photo
diode for optical output monitoring. This is suitable for such
applications as FTTH (Fiber to the Home)systems.
FEATURES
1550 or 1520nm typical emission wavelength, FP-LDs
Low threshold current, low operating current
Wide temperature range operation
(Tc=-40 to 85deg.C)
•φ5.6mm TO-CA N package
Flat window cap : ML920J45S, ML925B45F
Ball lens cap : ML920K45S, ML925C45F, ML920Y45S
