Overview

The PF587A is a 0.8 metre certified USB4 cable rated at 40Gbps, carrying DP1.4 video up to 8K@60Hz and Power Delivery up to 100W, with an E-Mark chip and Thunderbolt 3 compatibility. Actual video output depends on the source device, display and any intermediate dock or adapter supporting the required DisplayPort video mode, link bandwidth and display settings, including DSC where needed. Before ordering, request test records for the selected cable length and device/display configuration.

The short length is a deliberate specification rather than a limitation. Sustaining 40Gbps is fundamentally easier over a short run, which is why passive cables at the top of the USB4 bandwidth range are short — and for the work this cable actually does, short is right: laptop to a docking station on the same desk, to a high-resolution monitor, to an external SSD or eGPU enclosure sitting alongside. A longer cable in those positions is slack to be managed rather than reach that is needed.

The TPE jacket and moulded housing keep it flexible and low-profile, so it coils tightly behind a monitor and does not lever on the port — appropriate for a cable that is permanently connected on a desk.

Where the requirement is charging a high-drain laptop or reaching further, the 2 metre PLT588 in this range carries 240W under PD 3.1 in a braided build.

The E-Mark chip reports the cable's capabilities to connected devices. Actual data speed depends on the modes jointly supported by the host and peripheral; up to 100W requires a compatible USB PD power source and receiving device to negotiate a power contract within the cable's rating. The chip alone does not guarantee maximum speed or power.

Branding and packaging are customisable for OEM/ODM orders.

Frequently Asked Questions

Is the PF587A cable certified and what does the E-Mark chip do?: The specifications on this page list a USB-IF USB4 Gen3 certification test record for PF587A (TID 6801). The E-Mark chip reports the cable's capabilities to connected devices to negotiate compatible data and power modes; the chip alone does not establish certification of the complete cable. This model is rated for 40Gbps data transfer and 100W PD power delivery; actual speed and power also depend on the connected devices.
What video and power specifications does this cable support?: The PF587A supports DisplayPort 1.4 video output up to 8K@60Hz and USB Power Delivery up to 100W. It is also Thunderbolt 3 compatible for extended device compatibility. Actual video output depends on the source device, display and any intermediate dock or adapter supporting the required DisplayPort video mode, link bandwidth and display settings, including DSC where needed. Before ordering, request test records for the selected cable length and device/display configuration. Reaching 100W requires both the power source and the receiving device to support and negotiate the corresponding USB PD power level within the cable rating; actual power is negotiated by the connected system.
Why is the cable only 0.8 metres long?: The 0.8m length is intentional for optimal performance at 40Gbps bandwidth; passive cables at this speed range are inherently shorter. This length suits typical desk setups like laptop-to-docking-station, monitor, or external SSD connections.
Can branding and packaging be customized for our orders?: Yes, branding and packaging are customizable for OEM/ODM orders. Contact us for details on customization options and order specifications.
What materials are used in the PF587A construction?: The cable features a TPE (thermoplastic elastomer) jacket with a molded connector housing, making it flexible, durable, and low-profile for permanent desktop installations.
