The buyer needs a USB-C to RJ45 path for a notebook that has no built-in jack. Quantity is often counted in pieces per seat. Driver support for the named operating system is the open item, not rack unit height.

A search for a cadyce ethernet adapter price is a buying question about a named USB or similar network dongle, not a warehouse listing on this desk. LinkScope Sourcing 22 records the host port, the PHY speed, and the destination, then asks factories to answer that same sheet.
Five lines belong on the sheet before any factory number is compared. Leave a cell blank when the host is still unknown, and label it open rather than copying a catalog photo.
| Line | What the factory should answer | Buyer mark if unknown |
|---|---|---|
| Host port | USB-A 2.0, USB-A 3.x, USB-C, or a captive cable length in centimetres | Port family undecided |
| Data rate | 10/100 Mb/s, 1000BASE-T, or 2.5GBASE-T, with the PHY name on the datasheet | Speed still a range |
| Power input | Bus-powered draw in milliamps at 5 V, or a separate adapter | Power path not measured |
| Connector | RJ45 8P8C, shielded or unshielded, and whether the jack is on the body or a pigtail | Mechanical drawing missing |
| Evidence | Current datasheet, driver list, and any FCC equipment authorization file that names the exact model | Family brochure refused |
Power over Ethernet is a separate question. A bus-powered USB dongle does not present an 802.3af or 802.3at watt budget. If the job is a PoE splitter, say so; do not fold that watt figure into a plain adapter line.
Impedance of the twisted pair is a cable-plant item, commonly discussed as 100 ohm differential. Ask the factory for the adapter PHY and the connector, then ask the cabling vendor about insertion loss on the patch cord. Those two replies should stay on different lines.
The buyer needs a USB-C to RJ45 path for a notebook that has no built-in jack. Quantity is often counted in pieces per seat. Driver support for the named operating system is the open item, not rack unit height.
Technicians unplug the jack many times a day. Ask for the connector mating cycle figure printed on the datasheet, and for whether the shell is metal. A 64 mm body that blocks the neighboring USB port is a fit problem even when the PHY speed matches.
A wholesale serial to ethernet adapter is a device server with RS-232 or RS-485, not a USB dongle. DB9 pinout, isolation, and the management method belong on that RFQ. See the inquiry catalog before mixing the two forms.
Background: a facilities buyer holds 40 notebook seats in one US metro and a target month, but the standard image is still on Windows 10 for half the fleet and Windows 11 for the rest. Process: the note lists USB-C, 1000BASE-T, bus power, and asks each factory for the chipset string and the driver versions those two images can load. Result: quotations can be lined up on piece count and destination while the image split stays visible as a deviation. The desk does not treat the note as a completed compatibility test.
No. The phrase is the measured product term buyers type. LinkScope Sourcing 22 is an independent sourcing partner. A factory may propose that named model or a different model. Each reply must name the manufacturer, the model, and the chipset. A photograph with a similar shell is not a match.
Host port, data rate, quantity, US destination, and the timing the quote should assume. Add driver operating systems, captive-cable length if the jack is not on the body, and whether an external 5 V supply must ship in the same carton. IEEE 802.3 is a question source for the PHY family. It does not certify an untested pair of host and adapter.
The written brief is sent as one sheet. Factories answer configuration, currency, Incoterm, freight, and exclusions. Headline unit numbers stay uncompared until those lines align. Optional budget needs a currency and a per-unit or whole-order basis. A high-end, mid-range, budget-friendly, or undecided preference is the buyer stance, not a rating already verified.
Switching capacity, forwarding rate, optical budget, wavelength, dispersion, VSWR, gain, MIMO, and channel width describe switches, optics, or radios. Copying them onto a USB adapter RFQ hides the real gaps: PHY speed, driver, and connector. Ingress protection matters when the dongle leaves a dry office. Say IP54 or another rating when the drawing shows the gasket that was tested, or mark the environment open.
Use the form for specifications, quantity, destination, and requested timing. The dialog on product cards uses the same fields in a narrow window. This band keeps the review list beside the form.
