Custom USB4 Cable for 40Gbps and 80Gbps Cables

Len-Link is a USB4 cable manufacturer supplying high-speed USB-C cable solutions to electronics brands, distributors, docking-station suppliers, storage-device companies and equipment manufacturers.

Our product range includes 40Gbps and 80Gbps full-featured cables, selected models supporting up to 240W Power Delivery and 8K@60Hz video, as well as LED-display, extension and flexible flat cable structures. Standard products and project-based OEM/ODM support are available for bulk purchasing.

Compare USB4 Cable Options

Selecting a cable by its USB-C connector alone can result in insufficient speed, charging power or video support. A qualified USB4 cable manufacturer should help you confirm the bandwidth, cable length, power requirement, video output and connected equipment before sampling.

How to Select a USB4 Cable

Choose 40Gbps or 80Gbps According to the Device

A 40Gbps cable is suitable for many existing docking stations, external storage devices, professional monitors and high-speed peripherals.

An 80Gbps cable is intended for newer systems that support USB 80Gbps performance. Using an 80Gbps cable does not automatically increase the speed of a 40Gbps host or peripheral. The final connection operates according to the common capability of the connected equipment.

Confirm Charging Power Separately

Data speed and charging power are separate specifications. A high-speed cable does not automatically support 240W charging.

For a 240W application, the charger, host, connected device and cable must support the required USB Power Delivery level. The E-Marker and cable power rating should be confirmed before placing a bulk order.

Verify Video Output

Confirm the target resolution, refresh rate and video capability of the host USB-C port. A full-featured cable can carry the supported display signal, but it cannot enable video output when the host or connected display does not support the required function.

Treat Cable Length as a Performance Requirement

Cable length directly affects the construction needed to maintain high-speed transmission. Buyers should provide the exact required length during the quotation stage.

Longer, extension or non-standard cable projects should be evaluated as complete connections rather than assuming that the performance of a short cable will remain unchanged.

USB4 Cable Development for Device Integration

Len-Link supports standard wholesale orders, private-label products and project-based OEM/ODM development.

MOQ depends on the selected structure, materials, branding method, packaging and tooling requirements. Customized models may require 500–3,000 pieces, while ready-to-ship products may have different quantity conditions.

Project development may address:

• Right-angle or low-profile connector structures

• Flat cables for restricted routing spaces

• Connector housing dimensions

• Cable flexibility and bending requirements

• Strain-relief structure

• Device-specific length

• External appearance and tooling

Samples can be used to confirm fit, function and appearance before pilot production. Approved specifications and artwork are then retained for repeat-order management.

Frequently Asked Questions

Is every USB-C cable a USB4 cable?

No. USB-C describes the connector. The supported data speed, charging power and video functions depend on the internal cable construction, electronic marking and performance specification.

Should we purchase a 40Gbps or 80Gbps cable?

Choose according to the connected host, peripheral and intended application. An 80Gbps cable is most useful when both connected devices support USB 80Gbps. A verified 40Gbps cable may be sufficient for many existing products.

Can the cable length and structure be customized?

Yes. Length, shell, braid, color and packaging can be evaluated. Flat, extension and other structures are available for selected projects. High-speed performance must be reconfirmed whenever the cable length or internal construction changes.

Can we test samples before bulk production?

Yes. Samples can be evaluated for device compatibility, data transmission, charging, video output, dimensions and appearance before pilot or mass production.
