What this cable does
This Fervit USB4 cable carries data at up to 40 Gbps and delivers up to 240 W of power over a 50 cm length. It suits laptop owners who need a single link for fast storage, docks and high-resolution displays. The cable is backward compatible with USB 3.1 and works with devices that support DisplayPort Alternate Mode.
Thermals noise and power
Passive construction means no fan noise and no active cooling to manage. The cable handles 20 V at 5 A for 100 W or 28 V at 5 A for 240 W charging while data moves simultaneously. Normal use stays within the rated voltage and current limits without generating noticeable heat.
When to choose this over a lesser cable
Choose this when you need 40 Gbps throughput for external SSDs or RAID arrays, or when a monitor requires 8K at 30 Hz or 5K at 60 Hz over one connection. It replaces slower USB 3.1 cables that cap at 10 Gbps and 100 W. If your workflow stays at 4K 60 Hz and 10 Gbps, a standard USB 3.1 cable will suffice.

Questions about this item
How do I connect this 50 cm cable for 8K@30 Hz video, and what port requirement is often missed?
Plug the USB-C ends into a USB4 host port and a monitor with a USB-C port that supports DP Alternate Mode; the monitor must explicitly support that mode or video will not appear.
Will the 240 W power delivery degrade or need recalibration over time?
The cable handles up to 240 W at 28 V / 5 A or 100 W at 20 V / 5 A passively; no firmware or recalibration is involved, but inspect connectors periodically for debris or bent pins.
What is the first limit reached during a sustained 40 Gbps transfer?
The 40 Gbps data-rate ceiling is the primary bottleneck; thermal throttling of the host or device controllers typically appears before the cable itself limits throughput.
