WAN Ethernet Cables- A Closer Look at Shielding and Conductor Materials
Wide-area network (WAN) Ethernet cables are the backbone of any network infrastructure. They connect different buildings and locations, allowing data to flow seamlessly between devices. However, with so many different types of WAN Ethernet cables on the market, it can be difficult to know which one is right for your needs. In this article, we’ll take a closer look at the different types of shielding and conductor materials used in WAN Ethernet cables, and help you choose the right cable for your application.
Shielding
Shielding is a layer of material that is applied to the outside of an Ethernet cable to protect it from electromagnetic interference (EMI). EMI can come from a variety of sources, including electrical devices, power lines, and even other Ethernet cables. Shielding can help to prevent EMI from interfering with the data signals that are transmitted over the cable.
There are two main types of shielding: braid and foil. Braid shielding is made of a mesh of copper or aluminum wires that is wrapped around the cable. Foil shielding is made of a thin layer of metal that is bonded to the outside of the cable. Both types of shielding can be effective in preventing EMI, but braid shielding is generally more effective than foil shielding.
Conductor Materials
The conductor material is the material that is used to carry the data signals in an Ethernet cable. The most common conductor materials are copper and aluminum. Copper is a good conductor of electricity, and it is also relatively inexpensive. Aluminum is a less expensive conductor than copper, but it is not as good at transmitting data signals. However, aluminum cables are often used in long-distance applications because they are lighter than copper cables.
In addition to copper and aluminum, there are also Ethernet cables that use fiber optic conductors. Fiber optic cables use light to transmit data signals, which makes them immune to EMI. Fiber optic cables are also more expensive than copper and aluminum cables, but they can be used in longer-distance applications.
Choosing the Right Cable
When choosing a WAN Ethernet cable, the most important factor to consider is the application. If you need a cable that is resistant to EMI, then you should choose a cable with braid shielding. If you need a cable that is lightweight and inexpensive, then you should choose a cable with aluminum conductors. If you need a cable that can be used in long-distance applications, then you should choose a cable with fiber optic conductors.
By following these tips, you can choose the right WAN Ethernet cable for your needs.
