Everything You Need to Know About Cat 7 Ethernet Cables

Cat 7 cables support 10 Gigabit Ethernet at distances up to 100 meters. This lets users set up consistent and reliable wired Ethernet connections in practically any local area network environment. Better yet, eBay has a broad selection of Cat 7 Ethernet cables and accessories needed to accommodate your computing setup.

The internal wiring of an Ethernet cable can either be straight-through or crossover. Straight-through cables'often referred to as patch cables'are the standard cables used to connect computers to hubs, switches, and the like. A crossover cable, on the other hand, is often used to connect one computer to another. A rule of thumb is that you use crossover cables to connect like devices and patch cables to connect disparate devices. Therefore, you would generally use a patch cable to connect a switch to a router and a hub to a PC, for instance, and you would use a crossover cable to connect the following:

• A switch to a switch
• A switch to a hub
• A router to a router
• A PC to a PC

Raw indicates that the cable doesn't have the RJ-45 connector attached. This is common when purchasing Cat 7 cable bulk. It allows the user to cut the Ethernet cable to the precise length required. Then, the RJ-45 connectors can be attached to both ends of the cable, or a different connector type can be used in networking scenarios that require them.

All Ethernet cables are limited with what is known as a copper barrier. This limitation is 100 meters'or about 328 feet. This distance is plenty for most networking environments. In networking environments that require longer wired solutions, there are a number of ways to accomplish it. Ethernet Extenders are network devices that can extend the limitation considerably. Another option is to use a fiber converter since fiber isn't as limited as copper, and the signal can be converted back to copper near the destination.

Yes. As long as the connector or cable sleeve isn't compromised, these cables will work fine in both cold and hot temperatures. Be mindful that many manufacturers make outdoor-specific cables that are more heavy-duty and feature a connector that is less prone to moisture, corrosion, and so forth.
