THE COPPER CLIFF

4K has pushed copper cables to its limits.


Copper Had a Great Run

Copper has been simple and cheap, but it can’t handle the bandwidth of high-performance video any longer.

A copper HDMI cable as thick as your thumb can only take a real 4K signal up to 7 meters before it is overwhelmed by errors. 8K video will require even more bandwidth (48Gbps) and a fatter copper cable, yet only carry the signal 2 to 3 meters.

Applications like corporate video, event venues, medical, and digital signage are already transitioning to optical. Soon applications with much shorter distances like home theater, gaming, and VR will need to make the transition.


Industry's Delayed Reaction

The industry has resisted the inevitable transition because optical solutions are more expensive and fiber is new to installers and integrators. Some have tried to maintain the status quo using copper wiring by either compressing or reducing the information in a video signal. With this approach, the incredible beauty of real 4K and 8K video content is downgraded in order to lower the amount of data moved from Point A to Point B. This is not a desirable tradeoff.

The Mixed Blessing of Video Over IP

One way to remain on a copper infrastructure is to convert video to data bits and treat video streams like data streams on a local area network (LAN). Benefits include flexibility, better manageability, and the ability to “borrow” data networking solutions. But there are downsides too. Running video over IP requires building and maintaining a stable, high-speed network and having the support infrastructure necessary to maintain 100% uptime.

The Fiber Future

Fiber has largely replaced copper across Telecom and Datacom networks. And now it’s coming to Videocom, to deliver Real4K™, Real8K™, and whatever else the future demands.
