Is the PF587A cable certified and what does the E-Mark chip do?

Yes, the PF587A carries USB4 certification with an E-Mark chip that identifies the cable's capability to connected devices, enabling full-bandwidth and full-power negotiation. This ensures reliable 40Gbps data transfer and 100W power delivery.

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.

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.

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.

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 identifies the cable's capability to the connected devices, which is what allows full-bandwidth and full-power negotiation to take place at all.

Branding and packaging are customisable for OEM/ODM orders.
