Coarse WDM
DiCon’s Coarse WDM is designed to multiplex and demultiplex
signals in metropolitan, access, and enterprise networks.
Coarse WDMs are low cost components for systems with
fewer than eight channels and feature wide 13 nm channel
passbands to accommodate variations in laser center
wavelengths over temperature.

Applications
Coarse WDMs multiplex and demultiplex signals in systems based
on an emerging industry standard grid with 20 nm channel
spacings. These systems use uncooled lasers and low cost Coarse
WDM components as an alternative to more expensive components
based on 100 GHz or 200 GHz channel plans.
Units: mm
