We all love great and smooth music. To achieve this, ensure you are using the correct audio cable, and it’s well fixed.
Audio is not complicated as long as you learn active noise cancellation and available audio connections.
When assembling the first sound system for your home entertainment, you’ll have to decide on the type of sound plug formats and cabling. Don’t worry; there are several options such as Optical, RCA, Coaxial, and HDMI.
HDMI is the most popular right now because of various factors. However, this article is about RCA and Optical cables.
We are going to highlight their differences and similarities in functionality. It will help you know which is better between the two cables.
RCA Vs. Optical
If you’re an ordinary person and not tech-savvy, you’ll find these cables to be highly confusing. You might also think that the audio cable is just one.
While RCA cables are associated with analog signals, the optical cables transmit digital multichannel audio signals as pulses of light. For this reason, the optical cables offer superior sound quality compared to RCA.
This type of cable was quite common in the olden days. It was before the invention of ultra-high-definition curved televisions.
RCA stands for Radio Corporation of America, which is the original manufacturer of the cable. RCA connectors are pretty beautiful and split into three. Mostly they come in three colors: red, white and yellow.
Today, RCA cable is used chiefly when audio and video need to be transferred at the same time between devices. For example, the yellow cable transfers video red for right audio and white for left audio.
It’s another way of transmitting both audio and visual simultaneously between devices. They perform similar functions as the RCA connectors, connecting devices with visible components like console and DVD.
However, the Optical cable is unique in its design. Instead of wires, it uses fiber optic cables to transmit light and signal.
The optical cables can be compared to the modern and most popular cable, the HDMI. The signal remains as clear as long as it is within effective distance.
However, if the distance between the devices increases, there’s a sudden drop in signal quality.
Some Of The Notable Difference Between RCA And Optical
1. Resistance of EMI and RFI
When compared to RCA, Optical cable is superior in transmitting audio. First, this is because it transmits better quality signals over long distances.
Second, it’s because Optical cables are not susceptible to radio and electromagnetic frequencies.
It’s because electrical frequencies flow through RCA cable, therefore, degrade the signal with distance.
As a result, the optical fibers are less prone to noise. However, if you are not keen, you won’t notice any difference in audio quality.
Optical cables tend to have better bandwidth compared to RCA. This means it will provide better quality audio and visuals.
Most optical cables pass the 24 bits/96kzh, but none goes above 384k. If you want to know the bandwidth of any of the two cables, you can test.
3. HD Audio Transmissions
Opticality is limited when it comes to audio transmission. Despite the years, the ability of RCA to transmit various audios makes it a buy.
It’s only HDMI and RCA cables that can send HD audios such as Master audio, DTS-H, and Dolby True HD.
The optical cable is more expensive than its counterpart RCA. Pricing has made many choose RCA over Optical.
However, this price can be justified. Optical cable has higher frequencies hence high pricing.
5. Camcorder recordings
RCA carries the day when it comes to camcorder recordings. Camcorders do require separate cables for video and audio. This ensures faster and quality processing.
The cheaper camcorders that do not have a three-channel jack tend to have low-quality transfers. The best ones have three separate channels. Meaning the RCA is the only cable that can be used.
Best RCA cables
Today, HDMI is most preferred because of several factors. However, RCA cable is very much necessary, and many appliances still use it, like televisions.
This cable was developed in the ’40s and has been used for various functions since. Here are the best types of RCA cables.

Best Alternative To RCA And Optical
It was launched in 2002 and has since been the most used cable. It offers greater bandwidth than RCA and Optical cables.
In addition, it allows playback of lossless audio formats like that of Dolby, DTS-HD, and True HD.
The HDMI is just a beast, and the competition offered by the other cables isn’t much. Throughout the years, HDMI has undergone advancements.
The modern ones provide incredible bandwidth and transmit more audio channels like Dolby, Atmos, etc. As a result, many devices do support HDMI.
RCA and Optical cables’ roles are pretty similar. However, there is some slight difference in the quality of transmitted audio.
Optical cables have been rated highly compared to RCA cables because of certain factors.
This does not mean the RCA cable is not a buy. On the contrary, it can be so valuable in certain circumstances, like when using a camcorder.
Unlike the fragile optical cables that cannot be bent tightly, the RCA is long-lasting. Your choice of the type of cable is dependent on your needs and the types of devices you’re using.
