400G DCO Optical Modules
400G DCO Optical Modules refers to optical communications modules in the named interface or line-rate class.

Product & engineering
Understand the product.
Host electrical interface, optics, modulation/processing, thermal design and link specification define the module; a nominal rate is not a complete link result.
What turns activity into demand
Component demand follows the supplied level and its integration into a host product or installation. Design qualification, production purchases and replacements are different buying events; do not count complete systems and their components as equivalent units.
The commercial boundary
Use the selected edition’s product level, geography, years and measurement basis. Materials, components, finished systems and services are separate commercial boundaries unless the edition explicitly combines them.
Which supplied scope and interfaces define 400G DCO Optical Modules?
Host electrical interface, optics, modulation/processing, thermal design and link specification define the module; a nominal rate is not a complete link result.
