Basically, the system will be developed to support 400Gbps data transmission. This will enable us to support the high-speed solution. The management interface will be used to get the status and control of the module.

CMIS modules have two physical interfaces for signal transmission:

The host interface is the high-speed electrical interface between the module and the host system. The host interface carries signals traveling from host to module (transmitter input signals) and signals traveling from module to host (receiver output signals). All electrical signals carried over the host interface are transmitted over the wire pairs, each of which is called host lanes.

The media interface is the high-speed electrical/optical interface between the module and the interconnecting media. The media interface carries signals that travel from module to media (transmitter output signals) and signals that travel from media to module (receiver input signals). Media interface signals are carried either over electrical wire pairs (Copper cables) or over optical wavelengths on physical fibers, which are called media lanes.
