Overview

The PF331A-0300 is a 3.0 metre HDMI 2.1 cable carrying the ULTRA High Speed certification, rated at 48Gbps for 8K@60Hz with 4:4:4 colour and 4K@120Hz.

Certification is the point of the product. At 48Gbps the difference between a cable that holds the link and one that does not is no longer visible from the outside, and an uncertified cable claiming HDMI 2.1 typically fails by dropping the display to a lower resolution or refresh rate silently — the user sees a picture and never learns it is not the one they paid for. A certified cable has been tested to carry the full bandwidth.

At 3.0 metres this is the length for a desk, an AV rack, a games console to a nearby TV, or a short in-room run. Shielding is specified at 160 aluminium wires with 95% coverage and EMI attenuation of -6dB, which is what keeps 48Gbps intact past the power cables and mains adaptors any real installation runs alongside. The 5.0 metre version in the same range uses a heavier 176-wire shield for the extra distance.

4:4:4 colour is documented on this length, which matters where a PC or signage player is the source and fine coloured text must stay sharp.

Construction is nylon-woven with an aluminium shell. Length, branding and packaging are customisable for OEM/ODM orders.
