APPLICATION
·~1.25Gbps
digital transmission system
·
Coarse WDM application
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.
FEATURES
