What does an ethernet look like?

Ethernet is a widely used technology that allows computers and other devices to connect and communicate with each other over a local area network (LAN) or the internet. But have you ever wondered what an Ethernet actually looks like? In this article, we will explore the physical characteristics and appearances of Ethernet cables, also known as network cables.

The Appearance of Ethernet Cables

Ethernet cables typically come in various shapes, sizes, and colors. However, they all share some common features. The most common type of Ethernet cable is the twisted pair cable, which consists of multiple pairs of twisted copper wires enclosed within a protective plastic jacket.

Now, let’s address the question directly. **What does an Ethernet cable look like?** An Ethernet cable typically appears as a thick, relatively stiff cable with modular connectors on both ends. These connectors, known as RJ-45 connectors, resemble oversized telephone jacks or rectangular connectors with ridges on the side.

The Connector

Ethernet cables feature a distinct connector called the RJ-45, which is used to establish the connection between devices. The RJ-45 connector has eight pins and is designed to fit into an Ethernet port or jack. These pins on the connector align with corresponding metal contacts in the port, allowing the transmission of data signals.

Common Ethernet Cable Categories

Since Ethernet cables come in various categories, let’s briefly explore some of the most common types:


What is Cat 5 Ethernet cable?

Cat 5 Ethernet cables are an older standard but are still found in some networks. They support data transfer speeds of up to 100 Mbps.


What is Cat 6 Ethernet cable?

Cat 6 Ethernet cables provide higher performance and improved speeds compared to Cat 5 cables. They can handle data transfer rates of up to 10 Gbps over short distances.


What is Cat 7 Ethernet cable?

Cat 7 Ethernet cables are designed for data-intensive environments. They can support speeds of up to 10 Gbps over longer distances and offer better shielding against interference.


What is a crossover cable?

A crossover cable is a specialized Ethernet cable used for direct device-to-device connections, such as connecting two computers without a router. The wired pin configuration is different from regular Ethernet cables.


What are patch cables?

Patch cables, also known as patch cords, are Ethernet cables used to connect devices to a network switch, router, or modem. They are typically short in length and come in various colors for easy identification.


What is a plenum-rated cable?

Plenum-rated Ethernet cables are designed for use in plenum spaces, which are areas above suspended ceilings or below raised floors. These cables are made from flame-retardant materials to meet certain building code requirements.

Ethernet Cable Colors

Ethernet cables often come in different colors, and while the color itself doesn’t affect the cable’s functionality, it can be useful for organization and identification purposes.


What color is a standard Ethernet cable?

The most common color for Ethernet cables is blue. However, you can find Ethernet cables in other colors like white, black, gray, yellow, and red.


Are there specific colors for different cable categories?

No, the color of an Ethernet cable does not indicate its category. Cat 5, Cat 6, and Cat 7 cables are available in various colors.


Can I use different colored cables for different purposes?

Yes, using different colors can help organize and differentiate cables based on their intended use or destination.


In conclusion, an Ethernet cable appears as a thick cable with modular connectors, known as RJ-45 connectors, on both ends. These cables come in various colors and types to suit different networking requirements. Understanding the appearance and characteristics of Ethernet cables can help you set up and maintain your network connections effectively.
