If better to use the panasonic dac, then should I go ordinary analogue interconnects, or the balanced pin cables? why? This problem gave birth to the use of fiber optics for HDMI cables. Like many fiber optic cables, these HDMI cables work based on light and a concept called total internal reflection.

On paper, HDMI eARC also makes the handshake between compatible devices much smoother and negates the need to activate HDMI CEC (which doesn’t always work properly) - so operating multiple products shouldn’t require any extra steps to get things up and running.

Many types of these cables have been invented, but only a few rival the versatility and performance levels of fiber optic HDMI cables. Another factor to keep in mind is durability. While most fiber optic cables are fairly durable, there is no denying how fragile fiber optic filaments are. Manufacturers will indeed do their best to ensure everything is protected, but if you bend the cable too much, you risk damaging the fibers. Conventional HDMI cables can also attain this data transfer over long distances, but they need amplifiers. Because of this, many people who want to connect huge displays to smaller devices tend to opt for fiber optic cables. Downsides of Fiber Optic HDMI Cables You will find HDMI cables in multiple sizes in the market. Some are around a foot, whereas others are several meters long. But if you are curious about the maximum length of an HDMI cable, no such thing exists. The official standard HDMI specification doesn't recommend a cable length. As long as an HDMI cable meets the performance standards and can successfully carry the signal from one end to another, it can be any size.

In 2017, HDMI 2.1 increased the supported bandwidth transmission rate to 48Gbps all at once, supporting video of 8K/60Hz, 4K/120Hz resolution and 16bit color depth, and dynamic HDR data transmission is possible, which can be compared to Dolby Vision . High-Speed HDMI Cable: This type of cable is designed to handle video resolutions of 1080p and 4K (30 Hz) as well as provide support for 3D and Deep Color. Bandwidth transfer speeds up to 10 Gbps are supported. It is optimized for HDMI versions 1.3 to 1.4a. Because the optical fiber HDMI cable is made up of optical fiber material, it is smaller and lighter than the conventional HDMI cable. Also, HDMI AOC ( Active Optical Cable ) supports higher bandwidth and transmits high-resolution audio like DTS-HD quality a udio and can even transmit HD videos without compressing them. You don ’ t have to worry about whether it can transmit a high-bandwidth of 4K video and 3D video signal.However, data transmission speeds using copper cables can’t match the transmission using fiber optics. With fiber optic, that distance maximum is absolutely smashed. As we explained in our other tutorial on HDMI length, a fiber optic cable can transfer data at a staggering 1000 ft. For most home applications, this is overkill, and this is why for commercial use, fiber optic HDMI is often used. For those huge LED billboards and stadium screens, the source is usually too far away to reliably use copper HDMI. In 2002, the earliest HDMI version HDMI 1.0 was launched with a maximum bandwidth of 4.95Gbps. It supports DVD, Blu-ray, and Rec. 709 color gamut in the video, and 8-channel PCM, 24bit/192kHz audio source, which means that it had been able to support 1080p full HD resolution and 7.1 audio system. I n 2004, Version HDMI 1．1 updated its function in DVD－Audio . DSD lossless format was added to the supporting list in Version HDMI 1.2 the next year. CP−AOCH/60 cables are thinner, lighter and more flexible than copper or even standard optical cables. They offer transparent EDID, HDCP and HDR support with no signal attenuation and reduced risk of EMI and RFI interference. CP−AOCH/60 cables are an ideal solution for maximizing signal integrity in critical AV installations.

There were two versions released in 2015: one is HDMI 2.0a with extra support for HDR; the other is HDMI 2．0b additionally supporting another high dynamic range technology HLG. Let’s talk about what makes a fiber optic HDMI cable different from a copper HDMI cable. While they may look similar, as we have learned, there are some differences when it comes to construction. While you might think there is a huge difference between the two, fiber optic HDMI cables really only aim to serve one purpose, and that is cable run length. As with other cables, fiber optic HDMI cables have some benefits and downsides. Remember to consider these before making a choice. Benefits of Fiber Optic HDMI Cables Unlike optical cables, copper-based HDMI cables have issues with interference and length. The main issue here is going to be the length. If you want to transfer 4K video over a copper HDMI, you can only reach around 30 ft. before you start having issues (more on that in our HDMI troubleshooting guide). The main downside to a coaxial digital connection is the potential transfer of electrical noise between your kit. Noise is bad news when it comes to sound quality, but it exists in all AV components to one degree or another. Unfortunately, using a coaxial connection enables noise to travel along the cable from the source to your amplifier.The cables are small, easy to use, and can support data speeds of up to 18Gbps. This makes them the perfect choice for high-resolution videos like 4K and 5K. As far as commercially available cables using fiber optics, the market has been growing over the years. Here are a few cables that you can find online:
