5 Things You Need to Know About Shielded Ethernet Cables

Shielded Ethernet cables are widely used, so you may know what they are. You may even be familiar with some of the advantages and disadvantages of using them. But if you want to dig a little deeper into the world of shielded Ethernet cables, here are 5 things you need to know.

 

1. A single-shielded Ethernet cable has the lightest available shield but still weighs 12% more on average than an unshielded cable. A double-shielded Ethernet cable weighs as much as 30% more than the unshielded version. This additional weight may not be a big deal if you are only running a few shorter cables, but if your network is using dozens or hundreds of shielded cables, the combined weight could be enough to damage a rack, cable ladder or other cable management infrastructure. 

 

2. Double-shielded cables  have both a foil and braid shield and can better protect data from EMI/RFI and alien crosstalk (AXT). This protection results in higher transmission speeds and fewer data transmission errors.

 

 

3. High-flex industrial cables are shielded and built for continuous or high-flex applications, and also employ special jacket materials to solve common industrial Ethernet problems. They are designed for environments where ordinary patch cables fail. These cables will not breakdown when exposed to oil based lubricants, making them ideal for robotic control systems on the factory floor.

 

4. Shielded IP67-rated and IP68-rated Ethernet cables use a hood around the male connector that can screw onto the barrel of a female jack for protection against moisture and dust. Shielding the cables and connectors ensures better performance and higher data transmission rates.  IP67 and IP68-rated cables are also protected from liquid immersion, giving them another layer of protection.

 

5. Shielded Ethernet cables provide maximum performance even in high EMI/RFI environments.   Category 6 shielded cables are designed to handle today's hi-speed Gigabit Ethernet applications. Category 6a cable assemblies offer true 10 Gigabit Ethernet speeds at frequencies up to 500 MHz, making them ideal for high speed computing applications often found in data centers. Both Cat6 and Cat6a shielded cables are designed to outperform with super speeds and shielding protecting your data from interference.
