Posted on Dec 22, 2020

In this article, we will discuss fiber versus cable internet. These days the internet plays a primary role in our lives. Until ten years ago, if you did not have an internet connection at home, you might seem just not interested in social media and web surfing.But today, the internet is an obligatory need for all.

Optical telecommunications is one of the most important data transmission means due to its wider bandwidth than copper cables and less latency than satellite telecommunications.

Many people take advantage of fiber optic internet, and some are still using cable internet. Both have their specific weakness and advantages.

Through this article’s information, you will be able to decide which one is proper for you in terms of speed, reliability, cost, structure, availability, etc.

Your connection will impact the quality of your online experience and directly impact the services you provide for your customers on your website.

The main characteristic of choosing an internet service for typical internet users is just high speed. But there is much more in this concern.

If you want to make the best decision about fiber versus cable internet, there is no way except having useful information about these two common internet access.

Especially if you want to develop your business via the internet, you must invest enough time to make the best choice that is reliable, meets your needs, and be affordable.

What Is Fiber vs Cable Internet

Data is transmitted in computer and telecommunication networks through three different medias: copper wire, wireless media, and fiber optics. The wireless network is highly efficient in satellite telecommunications, but it is unprotected.

Wireless media is extremely sensitive to noise and is so noisy that even wind and rain noises affect it.

Copper cable and Optical fibers are two communication channels widely used in data communication networks.

Choosing the right type between coaxial cable vs. fiber optic internet is a must for network administrators. For example, temperature as an external and uncontrollable factor can affect the performance severely.

Cable Based Networks

Cables provide better performance than wireless media in data transferring. That’s why different types of copper wire cables have been being used widely in connecting computer devices.

This issue makes the cable a great choice that can be used to connect computer devices in a local network or internet network. Cables are copper wires with various models and types with their weaknesses and advantages.

Copper metal is relatively soft and conducts heat and electricity very well. It has the second grade in the most conductive metals (after silver).

This electrical property makes it an excellent choice for data transferring in internet networks.

The main weakness of this system is resistance.

coaxial cable- core of copper cable

When communication signals cross through the copper channel, they get weak.

The signal attenuation through the copper medium will lead to speed limitations and make it hard to transfer data signals for long distances.

Types of Copper Cables

Network administrators use two kinds of copper cables for data communication, including:

  • Twisted Pair cables: most widely used for computer network data transmitting.
  • Coaxial cables or coax: coax cable has a copper core insulated with aluminum and a copper shield with an outer plastic layer. They can supply an internet network.

Fiber Optic-Based Networks

Fiber optics are thin strands of glass that can carry pulses of light.

The light that can contain the desired information that we want to send across far distance.

Fiber internet versus cable: What is fiber optic?

As mentioned, Optical fibers are long, thin strands made of clear, pure glass that are as thick as a human hair!

Optical cables consist of a large gathering of these strands used to transmit optical signals over long distances.

Of course, this is not their whole usage. They are also used for medical photography and technical examinations in mechanical engineering.

Fiber optic channel

Light beams passed From origin to destination will be sent to a device that can change light pulse into electrical signals that are easy for computers to read and process.

So as you can guess, we need two crucial devices on two sides of a fiber optic communication system that can convert light pulse and electrical signals into each other:

  • The transmitter: converts the electronic pulses into light pulses to transmit through the optical fiber cable.
  • The receiver: it decodes the light pulses into a digital signal.

One of this media’s strengths in fiber versus cable internet comparison is that optical fiber channels are immune to radio frequency interference signals.

these channels transmit a high amount of data at high speed in the presence of electromagnetic interference.

Fiber Versus Cable Internet


fiber cable internet speed is higher than cable internet. It delivers faster and more consistent data speed even in peak usage times than most ISP users are online.

Copper cable infrastructure is limited in bandwidth. They usually offer asymmetrical speeds, which technically means more download bandwidth than upload.

For example, you may choose a plan with download speeds up to 100 Mbps. But you can upload data just in 10-20 Mbps.

a comparison between Fiber Optic and Cable Internet Speed

But this doesn’t mean that cable connections are slow. Some ISPs can provide up to 1000 Mbps(1 Gbps), which is excellent for meeting almost any online needs.

The table below can give you a big picture of these two types speeds. (reference: all connect) *Note that coaxial cables have data speed limits. In this table, some ISPs provide up to 1 Gbps speed through cables, but as copper cables are not dedicated channels, they might be shared between multiple users. The typical cable internet rate is 10-500 Mbps for download and 5-50 Mbps for upload.

Fiber Optic Internet vs Cable Speed /ISPFiber Optic InternetCable Internet
Cox1000 Mbps10-940 Mbps
Mediacom1000 Mbps60-1000 Mbps
Optimum300-940 Mbps
Xfinity25-2000 Mbps
SuddenLink100-1000 Mbps100-1,000 Mbps
Verizon Fios200-940 Mbps
Windstream1000 Mbps
Spectrum100-940 Mbps
Shentel50-1,000 Mbps


On a large scale, while constructing an Internet service from scratch, fiber cable internet installation is less expensive. Fiber optics are cheaper than copper, but detectors and optical amplifiers are more expensive.

Overall, because the optical signal loss is much smaller, the amplifiers’ number will be less, and the whole system’s cost will be lower.

Fiber cable internet price and cable internet price vary according to speed, data capacity, and contract time. You can see the price range of several ISPs fiber versus cable internet below: (reference: all connect) 

Fiber Cable Internet Price/ ISPFiber Optic Internet Price/moCable Internet/mo
CenturyLink$49.00 – $65.00
Cox$29.00 – $99.99$29.99-$99.99
Optimum$45.00 – $80.00$40.00-$65.00
Suddenlink$35.00 – $75.00$35.00-$75.00
Verizon Fios$39.99 – $79.99 
Xfinity$25.00 – $67.00$29.99-$299.99
Windstream$24.99 – $299.99 

Fiber Optic vs Cable Internet: Availability

Fiber-optic internet is not as accessible as cable internet, so restricted availability is the main drawback of optical internet, and widespread availability is the benefit of cable internet.

What is the difference between cable and fiber internet Bandwidth?

Bandwidth is the difference between the highest and lowest frequencies of data transmission in a system.

The higher the bandwidth, the higher the data transfer rate.

What is and fiber internet and cable internet bandwidth?

Investing in fiber optic internet can significantly increase your bandwidth potential.

Fiber optics have a much higher bandwidth than conventional cables and can transmit data at bandwidths up to 10 Gbps and above.

Copper wire infrastructure and TDM technology are very limited in nature.

Because they were initially designed only to send voice calls and as a result, the bandwidth demand was not high. For example, The T-1 can only operate at 1.5 Mbps.

Fiber internet vs cable internet: Reliability

In terms of fiber vs cable internet reliability, according to the many advances that fiber and cable internet have had so far, both of them are reliable and can provide high-speed connection.

But in active systems like cable internet, which depend on electric power, you must know that blackouts may impact your internet connection.

Fiber-optic networks are passive, so usually, you won’t experience an interruption or going down in case of power outages.

Fiber internet vs cable – How they work?

The concept of transmitting an electrical signal through copper cables are clear in cable-based networks, so there is no need for further explanation.

But to understand fiber internet vs cable systems operations, you need to know more about fiber optic cables.

Here is an example to describe how fiber optics work. Suppose you want to use a flashlight to illuminate a large, straight corridor.

The flashlight light will directly lighten the hall according to its exposure power.

Due to a straight light beam path, the flashlight can illuminate the desired range.

But what if the place has corners? What problem will you encounter, and how will you solve it?

– You can use a mirror in the corridor corners to reflect light from the relevant angle.

What if the corridor has many corners?

– Yes, it is true; you can use several mirrors along the entire length of the wall. In this way, the light moves from one point to another, and by multiple reflections, it can continue on its way.

It is similar to what happens in fiber optics. Optical fiber uses light to transmit data streams by using two glass layers and the light refraction law.

With the sophisticated design of layers and their refractive index, the light can travel to reach its destination. (for further information read: How Fiber Internet Works )

Due to the high speed of light and multiple equipment in its path (like amplifiers), the transmitted data reaches the destination with very high reliability during transmission.

    It leads to two valuable results: One is that the optical fibers will not affect each other. The other is strong electric and magnetic fields do not affect the optical fibers.
    So there is no risk of interference, and engineers can place optical fibers along with high voltage cables in power transmission lines.
  6. Low power consumption: Due to law signal attenuation, it is possible to use transmitters with low power consumption than electric transmitters that use high voltage.
  7. Appropriate for digital signals: fiber optic is suitable for transmitting digital information.
  8. Non-flammable: Due to the lack of electricity, there will be no possibility of fire.
  9. Lightweight: A fiber optic cable weighs far less than a copper cable, and this factor is helpful in the operation, installation, and maintenance of the fiber.

    Cont. Advantages of Fiber Optics  Over Cable

  10. Flexibility: Due to fiber optics’ flexibility and data send and receive possibility, it is used in digital cameras in medical photography.
  11. Temperature resistant: Optical fiber is more resistant to temperature change than copper wire.
  12. More speed: Fiber optic cable is much faster than copper cable.
  13. Newer infrastructure
  14. Decay resistance: Unlike copper wires, optical fiber is resistant to decay and has the ability to transmit data over distances of 50 km or more without loss of quality.
  15. Easy upgrade: With technological advancement, there is no need to change fibers, and only electronic equipment should be upgraded.
  16. Stability: In fiber optic cables, the possibility of disrupting data transmission and being affected by all types of electromagnetic noise, including radiofrequency noise or nearby cable noises, is low, so it is stable.
    In general, optical fibers are well protected from interference with other communication channels, whether optical or electrical.
    That is, they have excellent radio frequency interference (RFI) and electromagnetic interference (EMI).

Due to the fiber versus cable internet advantages, engineers use this type of telecommunication on a large scale.

But the fiber-optic network has two main downsides, including limited availability and limited plan variety.

It means that you cant apply for fiber-based internet in any area.

The reason for the popularity of high-speed cable internet service is the availability of this technology.

Fiber vs Cable Internet for Gaming

Even if you are not into online gaming, you may have heard the word ping at least once. Ping is, by far, one of the most determinant factors of the online gaming experience.

Especially in competitive games, it can have a profound effect on the result.

Fiber vs Cable Internet for Gaming in fiber internet vs cable

Briefly, ping is the delay between your computer and a remote device. Ping tells you how long it takes for a packet of data to be transferred from your computer to the intended server and then returned to you.

In web browsing, the delay between clicking a link and loading determines the ping. It takes a while for each packet to move between your computer and the server.

Ping is extremely important when playing online games. It determines the delay between order and action, such as shooting a person or detonating ammunition and having it done.

So the lower the ping, the less the latency, and all your orders will be executed almost immediately.

So compared to cable internet vs fiber for gaming, we can say fiber optic is usually better.

Since fiber optics generally offer higher speeds and lower ping, gamers can download faster and react quicker! Also, due to the symmetric structure, it provides equal download and upload speeds.
