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
