Faster internet connection speeds are becoming more and more important with the advance of technology. Apart from speed, another important parameter is connection stability. Fiber optics technology offers the best of both worlds!

That being said, many users will be interested in how to make their connection the best it can be by purchasing proper modems and routers. Fiber optics technology doesn’t use the same modems as other technologies and you often don’t have a say on which one to use.

Learn about the difference between routers and modems, which fiber optic modem and router are the best, and what fiber optics actually is!

Difference Between Modems and Routers​

There is one misconception we should clear out for those unfamiliar with internet networking technology. You can often hear people using the terms “router” and “modem” interchangeably but they are quite different. The info below might help you realize what to look for when making your next modem/router purchase!

The core difference is simple: a modem connects your device to the Internet and a router connects your device to a local network!

What does a Modem do?

A modem is a bridge between the infrastructure (cable, fiber optic, telephone or satellite) of your Internet Service Provider (ISP) and your Ethernet cable output that you can connect to a router or a computer. An example of an ISP is Comcast/Xfinity, but there are many out there. For fiber, telephone and cable connections, a single cable from your ISP is the input and an Ethernet cable is the output. Different ISPs have different modems and you must use the one that will work with your connection. Routers, on the other hand, can be chosen manually as their input is the standard Ethernet cable.

What does a Router do?

A router doesn’t actually need a connection to the Internet. Its primary function is to connect multiple devices/networks and manage all traffic between them. For example, a router can be used to establish a Local Area Network (LAN) where your devices can communicate amongst each other as long as they are physically or wirelessly connected to the router. However, its most common use is to use one connection to the Internet and enable multiple devices to use the same Internet connection.

Combining Modems and Routers

Many people might wonder why routers and modems are still two separate devices. Let’s face it – no one will use their Internet connection on a single PC with multiple smartphones, tablets, and laptops laying around our houses! That is why routers and modems can be found in a single device. While saving on space and possibly money, you lose the ability to simply switch to a better and a faster router any time you want.

Best Fiber Optic Modem

When purchasing a fiber optic Internet plan, your ISP will install its own fiber optic modem that is often referred to as an Optical Network Terminal (ONT). Basically, it transforms the optical signal you receive and it provides an Ethernet port you can plug into your fiber optic router.

So worrying about the best fiber optic modem is pointless as you’re stuck with the ONT that you’re given.

Best Fiber Optic Router

Since you have no word in choosing the ONT, you can maximize your network connection speed by using the best router possible. The most important thing about choosing the perfect fiber optic router to support your high-speed fiber optics connection is that it doesn’t throttle it.

Make sure the maximum supported router network speed is bigger than the network speed offered by your ISP. Once you’ve figured out what range you’re talking about, you can settle for the perfect router! If your maximum network speed is, for instance, 1 Gbps and your router’s maximum speed is 100 Mbps, it’s obvious that it will throttle your connection and slow it down.

If you own Alexa or if you plan to, in the future, consider buying a router that supports Alexa Voice Commands. Having a router stand out from your smart home is never a plus. Depending on whether you have children or how much you care about online safety, you can choose routers with built-in parental controls, firewalls, and other security features.

Below is a top-4 list of fiber optic routers that we consider to be at the top of the market and that support high bandwidth connections!

What is Fiber Optic Technology?

Fiber Optic Cable

We often hear about fiber optics as a term being thrown around when talking about high-speed Internet connections. However, many people don’t know what the term actually represents and what about it is useful to make your Internet connection that faster.

Fiber optics are long, thin, and flexible strands of fiber made of either drawing glass or plastic. Fiber optics (or optical fibers) are extremely thin, with the diameter of a single strand being similar to the one of human hair. These strands are used to transmit light from one end of the fiber to another and, when stranded together in a large number, they make optical cables.

Fiber Optic Testing

Fiber optics are used for data transmission. In electronics, different voltage levels are used to signalize either a logical 1 or 0. Using fiber optics, voltage levels are replaced with “light” or “no light”. Since light travels much faster than electrons, you can expect such data transmission to be much faster. This is in no way a new technology. Fiber optics have been used for more than a century but it’s only in the last 40 years that its development has exploded. Some of its most significant applications include:

Why is Fiber Optics Better than ADSL and Cable?

Fiber Optic Installation

ADSL and Cable connections are quite fast for today’s standard but they are simply not fast enough for the future. The main reason is the Internet of things, a system of connected devices that can communicate amongst each other without human interaction. Here is a list of several major advantages fiber optics has over the competition:

  • Extremely high speeds – Since light is most definitely the fastest thing in the universe, it provides this technology a bandwidth advantage that can’t be achieved with metal wires.
  • Longer transmission distance – When transmitting data using metal wires, power loss is a major problem. Power loss in fiber networks is mostly related to light reflection and faulty installations so they can be minimized with proper connections.
  • Data transfer can be either analog or digital – Even though both options are possible, sending data as digital signals is a major advantage as it doesn’t require analog-to-digital conversion.
  • Electromagnetic interference resistance – No electricity means no electromagnetic interference. This is the most important source of noise in the copper wire transfer. Without this problem, fiber optics can almost be considered noise and error-free. This also implies safety from lightning strikes!
  • Small size – With fiber optic cables being quite thin in diameter, they take up less space and are easier to accommodate.
Fiber Optic Cables

Still, fiber optic technology is not perfect. Cost is the first thing that comes to mind. However, we must point out that its price decreases exponentially from one year to another and it should meet with copper wire installation in no time. Installing fiber optic cables is quite difficult. They are easy to break. Faulty connections and improper installation can be a source of power losses and errors during transmission.
