SFP versus QSFP-family pluggable I/OWhich host cage and module family is documented? Form factor does not establish link capability.↗OSFP versus QSFP-DD host formsWhich pluggable-I/O host form does the equipment documentation identify? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.↗CFP2 versus CFP4 host formsIs the pluggable host connector the 104-position CFP2 form or the 56-position CFP4 form? Connector-family identity is only the first layer; implementation-specific electrical and protocol requirements still need exact documentation.↗
Discovery is not a compatibility verdict.
These discovery surfaces route and reorganize facts already represented in the atlas. They do not add electrical ratings, universal pinouts, measured tolerances, exact-device support, wiring approval or an end-to-end compatibility result.
