SFP versus QSFP-family pluggable I/O

Which host cage and module family is documented? Form factor does not establish link capability.

Computer-generated illustration, not a photograph. — P200 · ConnectorSFP / SFP+ / SFP28 host connector form

How they differ

SFP / SFP+ / SFP28 host connector form Identify the host cage and exact module standard separately, including speed, media and vendor/device support.
QSFP+ host connector form Read the exact host and transceiver specifications; use the connector form only as the first identification step.
QSFP-DD host connector / cage form Confirm the exact host cage, module standard, firmware/vendor support and media before treating a module as compatible.

Key distinction	The same physical module family can carry different electrical/optical standards; form factor alone does not establish link capability.	A QSFP-family cage does not by itself establish Ethernet generation, optics, copper reach or module support.	A QSFP-DD cage outline is not a guarantee that any given module, link rate or breakout mode is supported.

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.BNC vs TNC coaxial connectorsBNC uses bayonet coupling while TNC uses threaded coupling. Connector family, impedance and application still need to be verified independently.DisplayPort connector vs DisplayPort 2.1The full-size DisplayPort connector does not identify the implemented DisplayPort generation, link rate or optional features.DisplayPort vs Mini DisplayPortFull-size DisplayPort and Mini DisplayPort are different physical forms. Mini DisplayPort shape also appeared on Thunderbolt 1/2 products, so function still needs device evidence.DVI-D dual-link vs DVI-I dual-linkDVI-D and DVI-I use related shells but have different contact arrangements. The analog-contact area is a key physical distinction.

Trace 8 claims to their source records

C200A · P200

Amphenol identifies an UltraPort SFP-family host connector as a 20-position hot-swappable I/O form used for SFP+ and SFP28 applications.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

Source links: S203 · Evidence trail → (private workspace)

C200C · P200

Amphenol describes UltraPort SFP as a 20-position hot-swappable I/O connector enclosed within a metal cage mounted on a host PCB. The host connector and cage are not the removable network transceiver itself.

Claim scope: V121 named-product or explicitly scoped manufacturer distinction only; no wiring instruction, independent engineering approval or end-to-end compatibility guarantee.

C200D · P200

Cisco depicts optical SFP modules with LC network connections and a 1000BASE-T SFP module with an RJ45 network connection. The SFP host-side form does not by itself identify the network-facing connector, medium or supported host/module combination.

Claim scope: V121 named-product or explicitly scoped manufacturer distinction only; no wiring instruction, independent engineering approval or end-to-end compatibility guarantee.

C201A · P201

Amphenol identifies its ExpressPort QSFP+ connector as a 38-position host interface.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

C201C · P201

Amphenol describes its ExpressPort QSFP construction as a 38-position surface-mount connector and a press-fit cage, with several cage configurations. These are host-side components, not an optical link specification.

Claim scope: V121 named-product or explicitly scoped manufacturer distinction only; no wiring instruction, independent engineering approval or end-to-end compatibility guarantee.

C202A · P202

Amphenol identifies the cited ExtremePort product as a QSFP-DD host connector/cage form.

Claim scope: V36 catalogue-expansion identification fact only; not independent technical approval, fabrication data, wiring instruction or end-to-end compatibility proof.

C202C · P202

Amphenol identifies V36-BAZ17-205E11A as a QSFP-DD 2x1 long cage assembly for an anchor-pin SMT connector, with light pipes and a heatsink. The cited part is not a complete optical transceiver or proof of host support.

Claim scope: V121 named-product or explicitly scoped manufacturer distinction only; no wiring instruction, independent engineering approval or end-to-end compatibility guarantee.

C202W · P202

Molex2027180103 lists76loadedcircuits, manufacturer NumberOfRows1,0.80mm mating pitch, right-angle surface mounting, copper-alloy contacts and high-temperature thermoplastic housing. The one-row property belongs to this connector, separate from cage port counts.

Claim scope: Exact named manufacturer QSFP-DD connector only; limited-information notice retained. No face layout, signal map, installed-system capability or universal row convention inferred.
