Can I Use a Phone Cable as an Ethernet Cable? Why the Answer is No!

Phone cables and Ethernet cables are two different things. Phone cables are for connecting a device to a phone line, while Ethernet cables can connect devices to a LAN or the Internet. Though they may look alike, they aren’t interchangeable. This article will help you understand how these types of cables are different and why you should never use one in place of the other.

The Difference Between Ethernet and Phone Cables

Ethernet cables and phone cables both look similar, but some key differences. Phone cables connect to a phone line, such as a landline or VoIP service. The ethernet cable connects devices to a LAN or the Internet.

This is why you should never plug one in place of the other. Plugging an Ethernet cable into a phone jack will cause damage to your device and disrupt your service. The same goes for plugging in a phone cable where you need an ethernet connection; it will disconnect your device from the Internet.

Use an ethernet cable if you’re trying to connect two devices with an ethernet connection. If you’re trying to connect one device with a phone line, use a phone cable. You can find these cables at retailers like Staples or online shopping sites like Amazon.

Why You Should Never Use a Phone Cable in Place of an Ethernet Cable

The most apparent difference between phone cables and Ethernet cables is the device they are used to connect. Phone cables are only used to connect a device to a phone line, while Ethernet cables can connect devices to a LAN or the Internet.

Another difference is the connector on each end. You’ll notice that one end of an Ethernet cable has an RJ-45 connector, which looks like an oversized telephone jack, while the other end has either BNC connectors or RCA connectors. The connectors on a phone cable are typically different depending on the brand and model but will usually have both RJ-11 and RJ-45 connectors on each end.

There are also physical differences in the connections: phone cables typically use screws, and ethernet cables use clips.

If you’re ever unsure of which type of cable you need for your device, be sure to ask us! We’re happy to help walk you through it and provide you with what’s best for your system.

How to Choose the Right Ethernet Cable for Your Needs

Ethernet cables are a type of cable designed to connect devices to a network. They can either be used on a LAN or the Internet. Before you purchase, it’s essential to know the difference between two different types of Ethernet cables: Cat 5 and Cat5e.

The best option for most people is the Cat 5e, as it has some enhanced features that make it more reliable and capable of carrying more data at higher speeds. In general, Cat 5e is faster and more durable than Cat 5.

In addition to those two options, there are also some other terms you should know about when choosing an Ethernet cable. These include:

1- Shielded Cable- This type of Ethernet cable can be used in environments with electromagnetic interference (EMI) or radio frequency interference (RFI).

2- Unshielded Cable- This type of Ethernet cable doesn’t have any protection against EMI or RFI interference, which will cause problems if installed in an environment where this is an issue.

3- Twinaxial Cable- This type of Ethernet cable is typically used to connect servers to network switches, reducing the number of points where EMI or RFI can enter the system.


Connecting your computer to the Internet is a vital part of modern life, yet many people don’t know how to choose a suitable cable. Today we’ll answer one of the most common questions: Can I use a phone cable as an Ethernet cable?

The short answer is no, and here’s why: Phone cables and Ethernet cables are designed for different purposes. If you’re looking for a cable to provide reliable, high-performance Internet to your computer, choose the suitable cable for the job. There’s nothing worse than getting your work done and realizing you’ve been using the wrong cable all this time.
