Thunderbolt 4 Cable for 40Gbps Workstation Connections
A workstation cable needs to do more than just look familiar. BC-DAC010 is a USB-C male-to-male cable offered for Thunderbolt 4 connections, with up to 40Gbps link bandwidth and up to 100W USB Power Delivery. The listed 0.5 m and 1 m lengths suit nearby docks, displays and external storage without leaving a long cable loop on the desk.
Tell us what sits at each end and which functions you need at the same time. That is more useful than choosing by “USB-C” alone: the host, dock, peripheral, and power source all influence the result. For a repeat workstation rollout, agree on the exact cable build and test one representative equipment combination before ordering the full quantity.
BC-DAC010 Product Specifications
| Item | Listed Configuration / Ordering Note |
|---|---|
| Part number | BC-DAC010 |
| Connector ends | USB-C male to USB-C male |
| Connection family | Thunderbolt 4; verify the ordered assembly and required compatibility evidence |
| Link bandwidth | Up to 40Gbps with compatible equipment; not a guaranteed file-copy rate |
| Power capability | Up to 100W, 20V/5A USB Power Delivery; requires a suitable source and receiving device |
| Listed lengths | 0.5 m / 1 m; other lengths require review |
| Cable jacket | PVC |
| Display requirements | Review 8K60 or dual-4K60 requirements against the host, dock, displays, and exact operating mode |
| Other USB-C equipment | Operation uses the capabilities shared by the cable and endpoints; a USB-only port does not become Thunderbolt |
| Certification and construction | Request model-specific certification evidence and the current drawing; a component name is not proof of finished-cable certification |
Specify the Workload, Not Just the Peak Speed
A 40Gbps connection can carry several tasks, but it does not give every attached device a separate 40Gbps channel. Storage, displays, and other dock functions share the connection resources. Include the drives, screens, and peripherals you intend to use together so the sample test reflects the real workstation.
Charging is a separate capability. A 100W-rated cable does not force 100W into a device or make a smaller charger more powerful. The power source, receiver, and cable must support the negotiated profile. Equipment that requires more power than is available may still need its own supply.
Check Display and Dock Compatibility
For a high-resolution display setup, provide resolution, refresh rate, color requirements, and the dock model. A connector that fits is not sufficient evidence for 8K60 or two independent 4K60 displays. The host graphics system, operating system, and dock output paths must support the chosen arrangement.
If your project centers on another connection family, compare the Thunderbolt 3 cable configuration or the broader USB-C cable range. Select based on the required protocol and equipment, not on the number alone.
Request a Defined Build for Repeat Orders
Send BC-DAC010, your preferred length, quantity, and equipment list with the inquiry. Include branding, packaging, and documentation requirements if they form part of your procurement process. The quotation should identify the agreed cable configuration so you can review substitutions in length or construction before production.
Check Connector Clearance Before Ordering the Cable
Check the connector body against the equipment recess and adjacent ports before selecting the length. A plug can fit the socket but still leave too little room for a nearby cable or a comfortable bend. Request the current drawing for the ordered build, including the space needed for service access.
For a workstation kit, approve the cable with the actual dock and laptop in position. Keep the chosen length and connector construction in the part specification so repeat orders preserve the fit you tested.
The listed options are 0.5 m and 1 m. These are the options for this model, not the universal maximum length for Thunderbolt 4. Send a longer-length requirement for a separate configuration review rather than extending the connection with an unverified adapter.
It is rated for up to 100W at 20V/5A. Actual charging depends on the source, laptop, and negotiated USB Power Delivery profile. A lower-power charger does not become a 100W source, and a laptop may draw less or require more power than this cable configuration supports.
Thunderbolt 4 is designed to work with earlier Thunderbolt and supported USB connections, but its available functions depend on the equipment and cable used. A USB-only port does not gain Thunderbolt capability. Provide the host and peripheral models when the project depends on a specific backward-compatible operating mode.
Request certification evidence for the exact cable model and length if required by your procurement specification. Separately, test the intended host, dock, displays, and peripherals together. A component designation is not proof of finished-cable certification, and a single successful connection does not establish every display or power mode.
MOQ depends on the selected build, length, branding, and packaging requirements. Send your quantity and customization brief for a quotation; we should agree on sample and volume-order arrangements for that project rather than assume a generic minimum.

Buying Thunderbolt 4 Cables for a Standardized Workstation
When you set up the same desk setup repeatedly, the goal isn’t just to buy a cable with a high speed rating. It is to approve a connection that works with the chosen laptop, dock, displays, and storage, then repeat that build consistently. A short acceptance plan can make purchasing and deployment much clearer.
Identify the Ports at Both Ends
Record the actual host and peripheral models, and confirm which ports you’ll use. USB-C describes the connector, while Thunderbolt identifies additional connection capabilities. A USB-only peripheral can still have the same physical socket. Make sure the purchase specification names the required protocol rather than relying on a photograph of the plug.
Review Certification at the Assembly Level
If the project requires certified Thunderbolt products, request evidence tied to the exact cable model and length. A named controller, an e-marker, or a promotional logo does not certify the complete assembly. Keep the approved documentation with the part record. Changes in length or construction should trigger a review, not the assumption that earlier approval covers everything.
Test More Than a File Transfer
Connect the display arrangement that users will actually run, then add the intended storage and peripherals. Check stable operation while these tasks run together. A link-rate figure and a storage benchmark measure different things; application throughput also depends on the drives, host, and workload. Record the test setup so later results can be compared meaningfully.
Separate Charging from Dock Performance
Review the dock or charger power budget and the laptop’s requirement. A cable rated for 100W cannot compensate for a source that supplies less power or a receiving device that negotiates a lower profile. Check charging under normal workload, not only when the laptop is idle. If the device needs a separate power adapter, plan space and routing for it.
Choose a Serviceable Cable Route
BC-DAC010 is listed in 0.5 m and 1 m lengths. Measure the distance after placing the equipment, including the space needed to disconnect and reconnect the plugs. Avoid a route that puts sideways tension on the connector. The available lengths for this model are not a universal maximum for Thunderbolt 4 technology; longer requirements call for a different, reviewed cable configuration.
Keep the Approved Sample Identifiable
Before a volume order, record length, identifying marks, equipment models, and the tested functions. Discuss labels and packaging that help installers select the correct cable. A defined build and a clear acceptance record are more useful than an unsupported promise that the cable works with every USB-C device.
Send your workstation bill of materials and required quantity to request a quotation. We can review the cable requirement against that equipment list and identify what needs confirmation before the rollout.
