Overview

The PF331A-0300 is a 3.0 metre Ultra High Speed HDMI® 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 Ultra High Speed HDMI® 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.
