TYPE
NAME
DESCRIPTION
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.
They are hermetically sealed
devices with the photo
diode for optical output monitoring.
APPLICATION
·~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
· Flat window cap, or Aspherical lens cap
