The 24' says it's not fiber optic. The 50' says it is. Could someone please clarify what the cable is? I need it to be fiber optic cable to run 4k@60hz on my projector. null

Not fiber optic

Stephentestacmc1 · Answer

These are very high quality. I was more concerned about the long runs so I purchased better quality cables. The system I am using isn’t 4K. The projectors aren’t either. It is a big concern if you run a 4K. I use the longer ones with repeaters too. Distance beyond 45-50ft it’s a must.

I can only assume that the packaging is accurate but here's how fiber optic HDMI works:

The converters inside the cable heads convert incoming electrical signal into optical on one end, and back into electrical on the other end. The cable is composed of fiber cables and copper cables. The copper cables are used for non-video information such as hot plug detection, grounding, and +5v power. The fiber strands carry all the video information. The light travels down the fibers using internal reflection, which allows the light to bounce off the cable walls similar to a bobsled. Light travels extremely fast (186,000 miles a second) so the signal arrives almost instantly without losing any quality.

Better than copper
According to HDMI.org "The longest HDMI cable runs seen to date have been achieved using fiber-optic cable, which is far less susceptible to attenuation and interference than copper. Electrically it is similar to an active cable or Cat 5/6 solution, the principal difference being the higher-quality optical cabling between the transmit and receive connectors. HDMI over fiber is a highly robust solution, effective in cable runs up to 100 meters or more."

I've used a 50' fiber optic HDMI cable and it works great.
