What Equipment Is Needed For Fiber Optic Internet

What Equipment Is Needed For Fiber Optic Internet – When it comes to terrestrial high-speed broadband connections, there are currently two competing technologies: cable and fiber optics, or Fiber for short.

This post will briefly explain both and provide some tips for dealing with each. Among other things, you want to be sure of which equipment you can get the next time you upgrade or change your Internet service.

If you live in areas where cable and fiber are available, you can use them together in a Dual-WAN setup, which is useful for those who work from home.

I wrote this based on my experience as someone who recently switched to 10 Gbps fiber after years of using cable. “Same” because I saved both.

Fiber internet vs. cable internet: The picture shows that both work. A cable modem (top) is connected to the cable network and the ONT works directly with the fiber optic signals. Both bring the Internet to a single wired device – this is where you connect to your Wi-Fi router’s WAN port. In this particular setup, you need two routers, or one that supports Dual-WAN.

Before we continue, let’s address the elephant in the room: your favorite DSL. Yes I know.

, DSL uses the same wire you used for good old-fashioned dial-up — your existing phone line — to deliver simple broadband connections.

DSL has declined significantly in recent years due to slow speeds and unreliability. Many DSL providers have slowly switched to Fiber as a replacement.

As the name suggests, cable internet is a broadband connection over coaxial copper wires originally used for television or cable television.

A modem is a device that functions as an amodulator and a demodulator. It converts service signals into computer data signals and vice versa. Since the service considered here is Cable TV, we have cable modem.

Cable modems use the standard DOCSIS, an acronym for Data over Cable Service Interface Specifications, to carry data signals. This is the only acronym you need to know in the world of cable internet.

Fiber Internet Delays

DOCSIS helps make broadband more accessible because it uses existing copper wires for cable TV – the infrastructure is already there.

And because coaxial cables work like mesh, DOCSIS is flexible. When a cable breaks, it only affects a few families. (In turn, cable maintenance can be difficult because finding and repairing a broken line can take a long time.)

The main disadvantage of DOCSIS is its fluctuating connection speeds – uploads are one-tenth (or less) of downloads – the so-called asynchronous Internet. This is the case

If you’re wondering why cable internet upload speeds are much slower than download speeds, the reason is quite simple.

When it comes to data delivery, the same concept applies to wiring, but this time the provider can lower investment and maintenance costs.

And it usually worked well, because in practice the customers received much more data (downloads) than they sent (uploads).

There are currently two main versions in use, DOCSIS 3.0 and DOCSIS 3.1 – and DOCSIS 4.0 will follow at some point. Consequently, choosing a suitable modem can be very difficult. So much so that it requires another part – more on that below after you finish Fiber.

Fiber does not require a modem because the wires are designed for data connections. Instead, it uses an ONT at each endpoint, which is short for an optical network terminal.

In other words, an ONT is an Internet outlet that connects to an Internet Service Provider (ISP) to deliver Internet to your home or office. Each ONT has (at least) one network port to connect to the router’s WAN port.

Although quite different in technology, fiber optic service from an ONT is similar to a modem to cable Internet subscription.

Both of these are terminal devices that carry the Internet to a specific location – at home or in the office. In particular, they are designed to connect to the router’s WAN port.

Types Of Fiber Optic Connectors And Their Uses

A modem converts signals between a service line and data. The ONT sends pulses of infrared light to the ISP server to transmit and receive data.

But they both have one thing in common: they need support from the provider to work. Each ONT or modem can work with multiple ISPs, but the ISP can dictate which modems or ONT modules it supports.

The point is, if you’re going to get your own terminal device, make sure you get one that your ISP supports.

Minor cuts aside, Fiber-optic gives you “high-quality” Internet thanks to a modern optical data line running (almost) directly from the provider to your home.

Among other things, this type of broadband provides high speed in both directions (upload and download) – this is synchronous Internet – currently up to 10 Gbit/s and faster.

On the downside, fiber is expensive – it requires new wiring – and usually has a fault. If a network breaks or goes down, the internet can be down for a large part of the population. But finding and repairing a broken line is much faster.

In general, fiber is the way of the future. It is clean, fast, versatile and specially designed for high-speed data networks. This cable is far superior to the old copper wires.

Furthermore, since TV services have moved to slow streaming, there is no need for new coaxial development.

Cable internet is about using the existing infrastructure until it is no longer suitable or worth maintaining, which is still in the future.

Here is a Fiber ONT from AT&T. Note the black Ethernet (data) port, which is a gigabit or 10 GbE multi-Gig port to connect to the WAN port on the Wi-Fi router.

That is, fiber is the only and preferred wire required for new developments in real estate and technology. In other words, if your area doesn’t have cable or fiber right now, it will get the latter.

Another thing to note is that many cable providers use fiber as their primary data lines connecting existing cable lines. So sometimes we have cable internet outages over large areas – the main fiber line may be down.

A Brief History Of Fiber Optics

When you order Fiber Internet, you get an ONT – your supplier installs it at your home.

An ONT is either a stand-alone unit or an embedded ONT (often called an ONR or

It is always better to get a separate ONT if possible for flexibility. This gives you the freedom to choose the Wi-Fi solution you want.

If you get a composite device like a cable gateway, you may need to make some adjustments to avoid double NAT.

Fiber Optic Communication

Some fiber optic providers install an ONT and then offer to provide you with a Wi-Fi device. In this case, say no and get your own router or mesh system.

This is the only thing you have to remember when taking Fiber. On the other hand, getting a cable modem can be quite complicated.

Again, the world currently uses versions 3.0 and 3.1 of the DOCSIS standard. (You don’t have to worry about previous corrections – thank goodness!)

DOCSIS specifications can be very confusing. First, it varies from region to region. For example, a combination of certain modem specifications may mean different speeds in the US than in the EU.

It also supports channels, streams, QAM and more. contains many technical features such as I don’t want to go into the details and I don’t care about them. Instead, let’s focus on the two standards and what they mean.

Simply put, with DOCSIS 3.0 you can judge the speed of a cable modem by the number of streaming channels it can handle.

There are downstream channels (for downloading) and upstream channels (for uploading). More streaming channels or shorter channels will switch to a higher speed.

Each modem comes with an indicator of the number of even-numbered channels it can handle. For example, the Netgear CM600 is a 24×8 modem. It has 24 down and 8 up channels.

In the US, the DOCSIS 3.0 standard delivers speeds of approximately 40 Mbps per channel for downloads and 4 Mbps for uploads – again, these numbers vary from provider to provider. As a result, the CM600 is limited to 960 Mbps download and 32 Mbps upload.

Typically, the number of DOCSIS 3.0 channels is up to 32×8. Thus, the download speed of an advanced modem of this standard is approximately 1.3 Gbit/s. And this is the maximum bandwidth of DOCSIS 3.0.

It is important to note that the modem supports a certain level of performance (indicated by the number of threads).
