What the desk records before any factory is contacted
Port and PHY
USB-A, USB-C, RS-232, or RS-485, plus the data rate the buyer can accept. 10/100 Mb/s and 1000BASE-T are different lines. 2.5GBASE-T is written as its own option when a host actually needs it. A blank speed cell stays blank.
Power path
Bus power at 5 V, with the milliamp figure the datasheet states, or an external supply in the same carton. Power over Ethernet is recorded when the part is a splitter. It is not assumed for a laptop dongle.
Evidence request
The note asks for a current datasheet, a driver list, and any FCC equipment authorization file the factory chooses to cite, each tied to one model string. A series brochure is marked insufficient. This desk does not issue the file.
Commercial basis
Quantity, US destination, currency, per-unit or whole-order budget if the buyer has one, and Incoterm. Lead time is a supplier statement to compare later. Optional supplier preference is high-end, mid-range, budget-friendly, or undecided, and it is not a grade the desk has scored.
How a brief moves
- The buyer writes specifications, quantity, destination, and timing in the requirement field.
- The desk checks that port, PHY, power, and evidence requests are readable, and sends open items back if a cell contradicts itself.
- Factories are asked to name the exact model, list deviations, and separate freight and exclusions.
- The buyer compares replies. Host testing, code review, and acceptance stay with the buyer’s own engineers.
There is no published founding year, audited factory list, or customer count on this page, because those figures are not in the sourcing brief. Interface questions are. Impedance, insertion loss, and return loss are raised when the patch cord is part of the purchase. Connector mating cycle is raised for bench use. Rack unit, forwarding rate, and switching capacity are left off unless the buyer is actually buying a switch, which is outside this adapter sheet.
Standards sit in the file as question sources. An IEEE 802.3 family name helps the PHY line. It does not prove the proposed dongle links to the proposed host. The same boundary applies to a TIA cabling overview and to an external reference about equipment authorization: applicability is checked on the exact model the factory named.
Procurement scenario: a named search with two acceptable paths
Background: the buyer typed a branded adapter phrase, needs 25 pieces for a US office, and can accept either that named model or a different shell if the chipset driver matches an existing image. Process: the sheet lists both paths, asks for model strings, and refuses a reply that is a photograph without a model string. Result: factories can answer with a named unit or a compatible unit, each with its own evidence row. The desk does not pick a winner and does not describe either path as tested in our lab, because this desk does not run that lab.
Read the deployment notes when the use is a cabinet rather than a dock, and the evidence guide when an alternative shell is on the table.
