ADSL vs. Fiber

ADSL and Fiber Internet connections are on two different playing fields. Each offer a myriad of advantages, but when you break it down and look at availability, speed, reliability and cost, you can really start to understand where each will or will not accommodate your business needs.

For more tips on finding a suitable Internet connection for your business, check out our post about things to consider when choosing an ISP.

ADSL
FIBER

Availability

ADSL connections are available in mainly urban areas—wherever you can get a phone line, you can typically get ADSL. You need to be within 22,000 feet from the phone company’s central office (CO) in order to receive this type of service because as you move farther away from the CO, the signal weakens and Internet speeds slow significantly.1
A fiber optic connection is available in limited areas–but that’s quickly changing due to the demand of faster speeds. Since fiber utilizes a completely different cable structure then ADSL, new cabling is required for service, therefore; it may be a while before it covers the same footprint as ADSL provides. Speed is not affected, however, by distance as is the case with ADSL.2

Speed

ADSL’s downloading speeds range from 5 Mbps and up to 50 Mbps in some areas, with upload speeds up to 1.0 Mbps. ADSL is an asymmetrical connection and can not offer the same upload and download speed.  Latency with ADSL usually ranges from 75 to 400 ms, depending on the location of your business.1
Speeds for a fiber optic connection are nothing short of impressive, ranging from 5 Mbps and 100 Gbps for downloads and uploads! Fiber is typically a symetrical connection so you’ll have the same upload and download speed. With an Internet connection like this, multiple users are able to download and upload, share files, and stream audio and video all at the same time with virtually no effect on performance.2 Latency is not typically an issue with fiber either.

Reliability

An ADSL connection is what’s considered an “always-on” connection, meaning your device is always connected to the Internet as long as it’s on and the phone lines remain active and undamaged.1

It’s important to keep in mind that if your telephone line is accidentally cut by a service worker or is taken out of service due to extreme weather conditions, your Internet will go down. If your business demands internet that’s highly available you may consider an additional connection for your business for it would be ideal to have a backup option for Internet access.2 Typical repair times are 24-48 hours depending upon the outage.

Of all of the Internet connections available, fiber is arguably the most reliable and the highest quality. Even in instances of power outages, it is far less likely than ADSL to be affected. In addition, fiber optic lines use glass as a conductor and therefore experience no interference from high-voltage electrical equipment or nearby power lines, unlike ADSL, which generates electricity.2  Typical repair times are 2-12 hours depending upon the outage.

Cost

Monthly prices for ADSL services can range anywhere from $20 to $90, depending on the speed you sign up for and the length of your contract, if there is one. Since phone service is necessary, you may endure additional charges for the phone line to be in working order, and installation fees may apply as well.3
The cost for fiber-optic is generally much higher than the cost of ADSL, ranging from $100 to $5,000+ a month. These prices can vary depending on your location, your desired speed and the terms of your service agreement. Installation fees and activation fees can occur but are typically waived with promotional offers or the signing of a 1-, 2-, or 3-year agreement.2

Cable vs. Fiber

Cable and Fiber Internet options are two of the most popular broadband choices available. Each have their pros and cons for industries large and small, so let’s compare them based on availability, speed, and reliability to know which will best suit your needs.

CABLE
FIBER

Availability

Availability for cable Internet is one of its biggest advantages over fiber-optics. If you’re in an area where you can receive cable TV, you’ll have the option of getting cable Internet.1 
A fiber optic connection is available in limited areas–but that’s quickly changing due to the demand of faster speeds. Since fiber utilizes a completely different cable structure than Cable, new cabling is required for service; therefore, it may be a while before it covers the same footprint that Cable provides.2

Speed

Cable can provide businesses with speeds all the way from 10 Mbps to 100 Mbps down and and 1 to 5 Mbps up, which is more than adequate for most small businesses.1 Bandwidth is shared with other users in the area, so speeds can slow down during peak, or work, hours. Cable generally has a latency of 100 milliseconds, whereas with fiber, latency is usually not an issue.3

Reliability

Cable Internet provides an “always-on” connection: as long as your device is on and cable lines are active and in working order, you’re connected to the Internet.3 If you’re in an area that experiences a lot of cable TV outages or interruptions, you’ll also experience the same for your Internet, so if you rely heavily on your connection to conduct business, it would be ideal to have a backup connection in place.1 Typical repair times are 24-48 hours depending upon the outage.

In addition, fiber optic lines use glass as a conductor and therefore experience no interference from high-voltage electrical equipment or nearby power lines, unlike Cable, which generates electricity.2 Typical repair times are 2-12 hours depending upon the outage.

Cost

Cable connections are often bundled with phone and cable TV services, which allows you a good price for your cable Internet; the stand-alone option will cost more, most likely. Installation fees may also apply with this service, but overall, monthly fees can be anywhere between $60 and $300 per month.4
The cost for fiber-optic is generally much higher than the cost of Cable, ranging from $100 to $5,000+ a month. These prices can vary depending on your location, your desired speed and the terms of your service agreement. Installation fees and activation fees can occur but are typically waived with promotional offers or the signing of a 1-, 2-, or 3-year agreement.2

T1/DS3 vs. Fiber

T1/DS3 and fiber connections are used primarily by those businesses that are heavily reliant on the Internet to complete the daily operations of business. T1/DS3 connections are a common go-to for many businesses, but the popularity of fiber is ever increasing. To know which will best suit your business needs, we’ll examine the factors of availability, speed, and reliability, and the cost related to each type of connection.

T1/DS3

Availability

Availability for T1/DS3 connections are one of its biggest advantages over fiber-optics. T1/DS3 utilizes the existing copper infrastructure and can typically be installed anywhere.

Since fiber utilizes a completely different cable structure than T1/DS3, new cabling is required for service; therefore, it may be a while before it covers the same footprint that  T1/DS3 provides.1

Speed

In the recent past, T1/DS3 connections were the standard for enterprise business. This technology is delivered over the existing copper infrastructure and can handle speeds from 1.5 Mbps to 45 Mbps. To deliver faster speed, for example, typically two T1 lines were bonded together to provide a speed of 3 Mbps. T1/DS3 are the most comparable to fiber as they both offer symmetrical speeds.  This allows multiple users to perform data-intensive tasks related to uploading and downloading at the exact same time.

Phone service is not a requirement; however, you may need additional hardware to utilize the  connection. Installation fees and activation fees can occur but are typically waived with promotional offers or the signing of a 1-, 2-, or 3-year agreement.1
