ML7XX11 SERIES
InGaAsP DFB LASER DIODES
TYPE ^{ML725B11F/ML720J11S}
NAME ML725AA11F / ML720AA11S
ML725J11F / ML720L11S
DESCRIPTION
ML7XX11series are DFB (Distributed Feedback) laser
diodes emitting light beam around 1310nm.
They are well suited for light source in long
distance digital transmission system.
They are hermetically sealed devices with the photo
diode for optical output monitoring.
APPLICATION
· ~1.25Gbps digital transmission system
FEATURES
· Homogeneous grating (AR/HR facet coating) structure
DFB
· Wide temperature range operation ( -40 to 85ºC )
· Low threshold current (typical 6mA)
· High speed response (typical 0.1nsec)
· φ5.6mm TO-CAN package
· Flat window cap, Ball lens cap, or Aspherical lens cap
