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
