Description

Details

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
