How Do Optical Fiber HDMI Cables Function?

Optical HDMI cables look like regular HDMI cables externally. However, instead of copper wires, they contain fine glass filaments. These transfer data over a longer distance. Likewise, they can maintain a high transmission speed.

A fiber optic cable will work without other devices. You won’t need a switch, A/V receiver, or an extender when you purchase it.

Optical HDMI cables rely on light for data transmission. These signal pulses pass through the thin glass strands. After that, the cable converts the light into signals upon reaching the displaying device.

Fiber Optic HDMI Cable Pros

Fiber cables have many benefits due to how they work. For example, send signals over distances of up to 300 meters. Besides, they aren’t prone to radio frequency and electromagnetic interference. When using these cables, you won’t deal with signal losses.

Another pro is that they are less costly in the long run. This is because they don’t need an additional power supply to work. Likewise, you won’t require repeaters for signal transmission.

The best fiber optic HDMI cables are light. Due to this, they can fit into tight spaces. You may also carry several pieces around with less hassle.

Other pros of optical HDMI cables are:

  • Some models have smaller ports for versatility
  • They offer excellent audio-visual quality
  • ·They are more resistant to corrosion

The Cons of Optical HDMI Cables

Fiber HDMI cables are great, but they also have some downsides. These connectors can’t work in reverse. Hence, you must plug in the output and input in the proper devices.

Plus, fiber HDMI cables are expensive to purchase.

Fiber HDMI Cable vs Copper HDMI Cable

Copper HDMI cables have been around since 2003. These have copper wires transmitting signals in electrical instead of light pulses.

Optical HDMI cables have a higher bandwidth. A standard copper cable has a performance of up to 10 gigabits per second (Gbps).

On the other hand, fiber optic cables are much faster. Some models have a high performance of over 60 Tbps. When using a fiber optic HDMI cable, you will transmit data faster.

Another difference between fiber optic and copper HDMI cables is energy usage. The latter consumes more energy (about 10W). Conversely, optical fiber HDMI cables are more efficient. Some models consume as low as 250Mw.

Standard HDMI cables can last about 10 years. However, their lifespan may shorten due to various factors. Such include:

  • The frequency of usage
  • Storage
  • Temperature variation
  • The quality of the outer material

A damaged copper HDMI cable will cause various issues. First, the quality of transmitted sound will be low. The displaying screen may also fail to respond after connection.

The best fiber optic HDMI cable lasts longer than copper ones. A standard model may stay in good condition for up to 50 years. Still, you should avoid snagging and folding it tightly to enjoy this lifespan.

 Here are other differences between copper and optical fiber HDMI cables.

1.  Copper cables are slower than their counterparts

2.  Fiber optic cables are difficult to tap. Hence, they offer better security during data transfer.

3. Copper HDMI cables are cheaper to install and maintain.

4.  Optical fiber HDMI cables are more fragile.

5. Copper HDMI cables are less immune to electromagnetic interference.

How to Choose the Best HDMI Cable

After learning about fiber optic HDMI cable vs HDMI copper models, you may wonder which is the best. Here are some aspects to consider when selecting a suitable option.

The Resolutions of Your Display and Video Source

The HDMI cables in the market can support various video resolutions. These are 720p, 1080p, 4K and 8K. When watching 1080p and 720p, you can comfortably use a copper HDMI cable. Still, high-resolution videos will require at least a 4k optical fiber HDMI cable.

The Distance Between the Devices

If your devices support 6K resolution at 60fps, it’s best to use an 8K fiber optic HDMI cable. With such, you can enjoy a quick signal. Besides, the cable will support a refresh speed of up to 60HZ.

Fiber HDMI cables function better than copper models over a long distance. Hence, consider using 8K or 4K HDMI fiber optic cables if your devices are far apart.

The Usage Environment

If you want to install HDMI cables in a wall, choose those with a CL2 or CL3 rating. These have a fire-resistant coating. Thus, they won’t burn or allow flames to travel along them. CL2 and CL3 coatings are available for both fiber optic and copper cables.
