PORT & CABLE / KNOW WHAT CONNECTS.
FIELD SHEET 05 — 05 / PLUGGABLE NETWORK / PRIVATE REVIEW
A fitting module is not an approved link.
Can an SFP28 optic or DAC be used in an SFP+ host because the cages resemble each other?
A shared host-interface family does not qualify a particular transceiver, host firmware, optical medium or negotiated mode. Check the switch or NIC vendor’s exact port and transceiver list before ordering.
Not yet verified. Module size and cage shape do not qualify a specific host or optical link.
Four evidence layers
- 01 / Cage and socket
- Amphenol UltraPort SFP series covers a 20-position SFP-family host connector.
- 02 / Port mode
- An equipment vendor must identify supported module types, interface modes and firmware conditions.
- 03 / Medium and peer
- Optic, DAC, matching cable/fiber and the far endpoint form a separate link qualification.
- 04 / Evidence limit
- Connector-series catalogue evidence is not a switch/module interoperability matrix.
Check in order
- Read the exact host port designation and its vendor-supported module list.
- Compare full optic/DAC part numbers, intended medium and host-approved operating modes.
- Confirm the far endpoint, link partner, optical/copper requirements and diagnostic status.
No cross-generation module operation, firmware support, optical budget, thermal qualification or actual network link is established.
What would resolve this?
Not yet verified. Module size and cage shape do not qualify a specific host or optical link.
Record these model-specific facts before making a decision:
- Switch/host model and supported transceiver list
- Exact module model, required mode and firmware
- Matching opposite-end module, fiber/copper path and conditions
If a required model-specific source is missing, leave compatibility unknown. Never substitute connector appearance, this illustration or the print sheet for product documentation.
