DESCRIPTION
APPLICATION
ML9XX11, ML9XX16 and ML9XX22 series are DFB
(Distributed Feedback) laser diodes emitting light
beam with emission wavelength of 1470 ~ 1610 nm.
They are well suited for light source in long
distance digital transmission application of coarse
WDM.
·~1.25Gbps digital transmission system
· Coarse WDM application
FEATURES
· Homogeneous grating (AR/HR facet coating) structure
DFB
· Wide temperature range operation ( 0 to 85ºC )
· Low threshold current (typical 8mA)
· High speed response (typical 0.1nsec)
· 8 wavelength with 20nm space at 1470 ~ 1610nm
· φ5.6mm TO-CAN package
They are hermetically sealed devices with the photo
diode for optical output monitoring.
· Flat window cap, or Aspherical lens cap
